VSTs in Linux
Posted on June 6th, 2009 at 10:57 pm by admin

If, like myself, you sometimes like to travel light… a laptop computer and a MIDI controller keyboard can be an easier option than toting an organ and a rhodes piano into a venue…

Also, if, like myself you prefer the stability and efficiency of Linux when presented with the thought of a glitch / crash / hanging note bringing your gig at Wembley Stadium to a grinding halt, there are still options for using your Windows VST plugins with a fair degree of success.

So, (presuming you also have a machine running XP),

Install WINE (the windows abstraction layer for Linux).

Download the freeware VSTHOST, and copy the files over to a new folder in WINE’s “windows” directory (eg C:\Program Files\VstHost). This provides a very straightforward application for controlling a network of VST synthesisers.

VSTHOST will not run out of the box because it requires a dynamic link library that is not included in the WINE distribution. Simply copy the file mfc42.dll from your REAL windows\system32 folder and place it in the \system32 folder in WINE.

In the terminal, navigate to …\VSThost.exe and run:
$ wine vsthost.exe

Or right click the icon and select “open with wine”.

Et Voila. Don’t forget to select your MIDI inputs first. I use an EE-MU MIDI to USB cable to get the data into my laptop. It seems to work out of the box on Ubuntu 8.1. I can’t vouch for other interfaces, but as all this software is open source you won’t loose anything by trying…

Jazz… Your Questions Answered!!!
Posted on June 1st, 2009 at 9:16 pm by admin

Here at the Blagoratory, we are always inundated with letters and questions, so, in a bid to inform and educate you, (the non-paying public), each month, we pose a choice selection of your queries to Dr Larrs Grooven, emeritus professor of Jazzmusikology at the Funkenskool for the international development of Grooviepeople

Dear Doctor… When I listen to this music, I am filled with a strange compulsion to dance. Am I allowed to do this? If so, how? – Pat, Brighton

There is no rule that says that you can not. However, due to health and safety reasons, plus the adverse affects of alcohol consumption allied with the lack of clear space in most clubs, bars and concert venues means that your efforts may be futile. People may also consider you to be in the possession of evil sprits. Historically, jazz grew up with dancing, (ragtime, boogie woogie, jive, latin jazz etc.) Suddenly, this all stopped at the end of the 40’s because musicians started playing so fast that nobody could keep up to it. This is a shame, because there has no developed a lack of physical response to the musical stimuli, and with lack of physical response comes zero emotional response. So here is my quick guide!

1. First, act naturally - you don’t want to get thrown out before your “dancing” has even begun. Sitting in a comfy chair, start to twitch your head from side to side whilst clicking your fingers (ON THE 2ND AND 4TH BEATS OF THE BAR PLEASE!!!). Doing both at the same time takes some co-ordination so you may need to practice at home. Try not to smile - you don’t want the jazz police onto you yet. DO NOT move your head forwards on each beat, it must be side to side otherwise you will look like a turkey

2. This accomplished, start to clear your head of conscious thoughts. Try concentrating on the bass player - he/she is usually zenned out because they have to spend the whole evening doing the same thing… Now, as you focus on the repetition, you will start to hear a faint voice in the back of your head… this is lady jazz…

3. You will past through a kind of transitionally phase known as “vague gyration in relation to the beat“. This is normal and is due to a what is known as the “Larrs Grooven Bebop singularity“, (similar to the shockwave that occurs as jets pass through the sound barrier), I should have mentioned that it is wise to remove all sharp objects before attempting the “freedom jazz dance” and to wear loose-fitting clothing. This will become apparent later.

4. At first you will be frightened, don’t be. Relax, go with the flow. You must surrender to what the voices in your head tell you to do, because now we is talkin’ JAZZ boy and you’re in for a roller-coster ride into the unknown… “I don’t want to do that - I don’t want to go that way!” you will scream… but Lady Jazz says “you is mine now boy and you are going to do as I tell you!!!” By this point you will probably be suspended in mid air - this is the first stage of levitation, just relax, try not to fight the voices in your head because if you do, you’ll loose the Zen energy and fall back down to earth. You’ve probably arisen the suspicions of the jazz police by this point and they’ll be making their way over to you from their base, (behind the raffle prizes). You’ve got to enjoy the moment whilst it lasts…

5. Some folks have experienced a bizarre sensation of total nudity by this point and this is probably due to the after effects of the “Larrs Grooven Bebop singularity”. Keep focused, and don’t worry about your clothes if they have “fallen off” by this point. You’ll never see any of these people again anyway. If you want to scream some form of encouragement to the musicians at this point you may do so.

6. This is as wild as it gets. Feel free to grip the tablecloth, perhaps clench a beer mat between your teeth. You can hear lady jazz shout in your ear “I hate to quote Maceo Parker at this point but SHAKE EVERYTHING YOU’VE GOT!” Obey.

7. By this point, hopefully the jazz police will have grabbed you and thrown you out of the club, having confiscated your raffle tickets. Congratulations, the Jazz Dance is over! I hope you enjoyed it - and think about the weight loss you may have achieved!

Dear Larrs, I have heard that the wicked rhythms of ragtime can destroy the higher brain functions. What can I do to help prevent this wicked curse that is sweeping the youth of our nation? Josie, Croydon

You must act fast. Firstly, you need to get an old sock and staple it repeatedly to your forehead. Next, you need to put on a clean suit of clothes and a tie, (the devil sure hates investment bankers). Put flowers in your hair to ward off the evil zeitgeists and finally paint giant love hearts on your face, hands etc.

Having completed all these steps you need to get out to the front of the “moosh pit” at a heavy metal concert and jump up on stage, using the mass media attention that your interruption will have caused as an opportunity to preach against the evil ways of twentieth century popular music. You will be mercilessly beaten to death, but your sacrifice might help your cause.

I am concerned that there may be some dubious underlying social references as regards some of the rhythmic and musical devices favored in jazz. Should I lock up my daughters? Mr A Nall, Southampton

I am a computer programmer, so in this case - I am sorry but I don’t have a clue what you’re talking about!

This is what the Hitchhikers Guide to the Galaxy has to say on Facebook:

“By the 24th century, Facebook had become a sinister Orwellian attempt to control us all,
A select few continued to fight for our freedom and individuality as one by one all things and people they held dear to them were drawn in as slaves to the new world order,
bleary-eyed they marched, zombie-like to their electronic tabernacles to throw themselves before the alters screaming “I love you America! I love you America…!
only one thing could save them,
a months processing at a secure rebel facility,
with only “VisageBook” to keep them company,
“VisageBook” is the world’s first inverse-social networking facility - you start off with everyone on the Galaxy as your “friend” and the winner is the first person to regain their individuality by sending an e-slap (in fact a high-voltage electric shock) to as many contacts in their addressbook, thus symbolizing the termination of “friendship”,
with in excess of 1000 million patients hardwired via implanted rectal electrodes into the network at any one time, the incentive to regain individuality is something of a matter of uttermost urgency…
thus “cured” - our patients start on a period of supervised probation in small groups, learning to re-adjust to verbal communication,
special privileges are rationed out to those show marked improvement,
(for example, an i-phone, covered in saliva might be given out for an hour, or for the best behaved, there is the promise of an X-box that has been chewed by a pack of rabid badgers),
following a few weeks of probation,
our patients are issued with new identities and sent out into the solar system to start new lives as painters, craftsmen, philosophers, musicians, artisans,
most took well to their new identities,
some, however, just chose to spend the rest of their lives lying on the ground,
staring up into space and crying in awe at the wonders of the universe…”

Soundtracks, Soundbites, Signs, Semiotics and Pork Scratchings…
Posted on January 21st, 2009 at 4:00 pm by admin

On of the great things about writing music for short films is the brevity of the medium. Longer forms tend to require set structural archetypes in order to sustain interest over a large space of time, (such as ABA, sonata form, variations, collage etc). Short forms, (say 2-5 minutes) can get quite interesting, because they allow directors the chance to take more risks with the narrative, perhaps abandoning the conventional notion of plot altogether, as is often the case in the film festival / art house movie genre, (almost to the point of cliché, some might say). After all, it can be rather futile to try and spin a complex story in such a short space of time, so a director will often concentrate on other elements, such as characterization, cinematography, editing techniques etc. Likewise, for the musicians / composers, it can be quite tough trying to say something meaningful in such a short space of time, (remembering to leave room for the speech and ambient sound of course), so what is often called for, is some kind of soundtrack that defies the conventional approach to melody/harmony/rhythm.

What attracts me as a composer, is the way in which I can use non-standard instrumentation, (how about a 2 minute soundtrack just for solo snare drum? How many sounds could you get out of one surface?). Often, when I go to film festivals, I hear great music, but a great deal of it seems to fall into the “I say chaps, lets get some ambient beats going here” or “how about another 5 minutes of moody post-Philip glass piano arpeggios?” Admittedly, these cliches are successful because they connect with very strong western cultural archetypes that we are subjected to on a daily basis. However, I tend to find some of these ideas a bit lacking in terms of different emotional colours, especially when were are dealing with cinema that is working on a higher level of subtelty that our standard fare. Its like trying to paint the world in red, yellow and blue when there are infinite shades in between, some of which are really difficult to describe because they elicit quite equally varied responses in different people because they have not been exposed to these “signs” at the same level. Indeed, there is no law that prevents the soundtrack from suggesting an entirely different interpretation to the film itself, (although this is treading in risky waters). Quote Bill Evans:

“I believe that all people are in possession of what might be called a “universal musical mind.” Any true music speaks with this universal mind - and to the universal mind in all people. The understanding that results will vary only insofar as people have or have not been conditioned to various styles of music in which the universal mind speaks.”

“Consequently, often some effort and exposure is necessary in order to understand some of the music coming from a different period, or a different culture than that to which the listener has been conditioned”.

“I do not agree that the layman’s opinion is less of a valid judgement of music than that of the professional musician…. since the professional, because of his constant involvement with the mechanics of music must fight to preserve the naivete that the layman already possesses”.
- Bill Evans “The Universal Mind of Bill Evans, Rhapsody Films

Well, face it, you didn’t exactly come to the film festival to get the latest blockbuster action did you? Its a great medium for me to package so-called “contemporary” music in a form that will be circulated to a mass audience via internet / TV / festivals etc. As described earlier, I like to use the opportunity to try out new combinations of sounds. (2 piccolos and a tuba anyone? Seriously?) But, increasingly, I am open to the idea of using unconventional forms, colours, spatial arrangement, contrasting genres / media. Small musical microstuctures that are held together by their own internal “poetry”, and by the system of syntactic and semantic connections to the film on screen. This becomes is almost a kind of musical “haikau” at times, (think of those microcosmic orchestral gems by Webern). I also like the idea of symbolic references, for example, a particular chord or colour could be a re-occurring structural “signpost”, that itself may also hold extra-musical associations. Stop and consider the musical “cliches” again; what symbolic references might they hold, (cultural, psychological, physical, nostalgia?). Do these vary depending on the cultural “conditioning” of the viewer? Is this a bad thing, or a reflection of our multicultural society? Think outside the theory…

Also, there is the use of the studio to consider, spatial, effects, mixing etc… This opens up possibilities that are next to impossible in real life, for example, getting some electronic sounds going against an African Choir, perhaps some commercial music mixed in and out phase with abstract percussive sound improvisation? (Not saying it’s a given formula for success), but its good to be open to new ideas…

“…if modernism was the fiery death of classical culture, then by analogy post-modernism is playing with the crispy bits” – Nick Peck

To chart my thoughts on listening to a film soundtrack [one that I have just completed]; a panning shot of a locomotive is accompanied by dissonant brass chords which move from right to left following the motion of the train. To some listeners, the voicing and articulation of the chord might suggest the sound of a train hooter, (US horns are often tuned to a triad). Throughout the soundtrack, this right to left panning is explored by a number of other sound layers. In addition, lower elements of the music seem to be suggesting the “clack-a-tee-clack” motion of the rails, but at other times this could be suggesting the heartbeat pulse of our “hero”. Another element is a celeste, which plays an ostinato that sounds likes a nursery rhyme, (distorted in rhythm and harmony). As our hero awakes from a violent dream, and falls back to bed in relief, this suggests the sound of a music box that might lull a child to sleep. However, this gradually emerges as a distorted version of a Bach Chorale, that a small number of listeners might recognize as “Es ist Genug” (“It is enough…”), played in distorted rhythmic canon by an army of bells of various shapes and descriptions, as [in a later scene] our hero seemingly prepares to take his own life. Even to those viewers who do not recognize the chorale, this choice of a Western-sounding hymn tune suggests some form of spiritual redemption, that either in life, or through death he might find relief from the nightmares that plague him throughout the film. The treatment of this passage, however is not without strong tones of Eastern Gamelan music, thus breaking any sense of tie with any religious connection. I wanted to hint at a more spiritual, not religious sense of questioning, which, (given the fact that the supposed suicide is not seen or heard) , leaves us questioning the possible dual outcomes of the film, (but, with an unusual sense of calm, given the violent nature of the preceeding subject matter).

In an earlier film (Two Glasses), I attempted a similar form of abstraction. The film was only 4 minutes long and involved no dialogue, portraying a potential marriage breakup between husband and wife. A reoccurring sound that we hear throughout the piece is a high pitched whistle, (which is in fact a single accordion note, sampled and filtered to isolate all but the highest harmonics). This sound might be familiar to some listeners who have tried the old party trick of rubbing a moistened finger over a wine glass, (a glass harmonica – another reference to the title of the piece). Also the “glassy” stare that the wife gives her deceiving husband at the start and close of the movie. At an earlier point in the film, the husband is portrayed making his way to the apartment of his secret lover. As he opens the door, the scene is accompanied by a crescendo on a single shaker. Why I chose this sound to build tension, I can’t remember, but in retrospect it bears a resemblance to the sound of the rattlesnake, (entering the viper’s den?), or could it be hinting at some kind of subliminal samba beat (frivolity?) Earlier, as the husband is seen making his way through a back alley, he is accompanied by a theme emphasizing 3rds and 7ths played by marimba and accordion. In this respect, the marimba plays a resemblance to its smaller cousin, the xylophone - an instrument often heard accompanying the mischievous antics of Cats & Mice in countless 50’s cartoons – the lightness of the percussive attack suggested gentle footsteps on a dangerous path of depict.

Once again, the fact that some sounds / events may suggest different interpretations to different viewers is all part of the fun for me. I like the idea of something that might suggest differing outcomes, perspectives and moods.

I want to stress that these are my observations on watching the films after having finished the soundtracks. This is just a kind of “after-the-fact” analysis from a semiotic perspective.

Does this kind of semiotic analysis deserve more of a place in our musical education? Or, on a more personal note, should this be more of a concern in our creative considerations as regards “Jazz” (or whatever improvised music is called these days). In some colleges, our analysis of “Jazz” often seems to be centered around a concept of “language” that is often little more than a kind of painting by the numbers. True linguistic analysis involves a deeper understanding of “assumed knowledge”, phrase structures and contours and that, in turn implies a study of semiotics. The best musicians develop an innate grasp of this concept regardless, but it strikes me that a music that tries to ignore any concept of this is, well… bound to die anyway…

“In the 1990’s jazz’s blood squirted all over the floor of American culture and its body and soul slowly escaped, leaving an empty shell twisted in the throes of death.” Watrous,“The Nineties” JazzTimes Sep. 2000

Or did it? It seems, (more so, in the last decade) that a new “wave” of thought has emerged, whereby a track is less of a structure for “blowing” and more about creating an instance of a mood. I would cite, as a well-known example, John Scofield with Medski, Martin & Woods on the album “A Go-Go”, in which each track acts as an attempt to conjure up a specific scene, (just like a series of short soundtracks for a surreal cartoon…. Ren & Stimpy hit Funkytown USA for a wild night of furball regurgitation, illegal meat products and corn-related humor). For instance, the track “Kubrick” is less than 2 minutes long, and features no “improvisation”, in the conventional sense (save murmuring tom-tom figure). As another example, the trio “The Bad Plus” have evolved a performing and recording style which, (as an antithesis of the jazz tradition), features strong doses humor, pop cultural references, extra-musical effects… suggesting a new paradigm for jazz whereby the sum total of the parts (i.e. the concept of the “track” as a single entity) is more important than everyone just tearing off a great string of solos…

Or on a bigger scale, the music of Maria Schneider, contains a large number of symbolic references, integrated into a large scale-developmental form, (which Maria readily cites as influences when describing the compositional process). Some of these are immediately apparent, such are bird calls heard on “Cerulean Skies” , some are more subtle; the irregular meters of “Hang Gliding” describing the heart pulse of a hang glider pilot preparing to launch into flight. Of course, a Jazz orchestra still has a fairly defined “sound”, (inherited at some distant level from Duke Ellington), but after all, wasn’t it Ellington who said that Jazz was a feeling, not an intellectual theorem?

Speaking of Ellington, I might even hazard a suggestion that increasingly, “jazz” is returning to the pictoral concept of earlier players? Tell the story of people, moods, cultures, ages. This is not a critic of anything that has happen since, and I am certainly not advocating any form of historical re-enactment. On the contrary, armed with new resources, the music still has the power to instantly tell the story of our age and the world we live in.

One of the occasional hazards of “art” is the need to admit to an overwhelming sense of humility. The more you think you are finding your feet, the more you are stuck by the enormity of the whole concept. The moment you think you have your “sound”, something else comes along. Of course there are no-out-of-the-box solutions. Here I am, somehow brought up on very structuralist musical post-Schoenbergain values (no idea why, seeing as I didn’t exactly grow up listening to Beethoven), calling some of those values into question. Schoenberg lamented the demise of “structural listening” amongst concert audiences, but taking my music appreciation into consideration (and rumor has it that I have musical education), I doubt if, ever, my primary motivation for attending a concert of Western Classical music has been to sit there clocking the instances of themes, development / forms etc. I am, of course, more interested from a sensual, not structural perspective, as are, I expect, the vast majority of audience members. However, Schoenberg also proposed a model of musical evolution within a particular culture whereby successive generations expand upon differing elements of the music. We now live in a culture where music, (including a great deal of experimental/contemporary music) is increasingly about creating short instances of a “feeling”, rather than a musical/artistic concept. I don’t feel that this was the case 10 years ago. Perhaps this is a product of the internet revolution, (music finding new outlets as bandwidth-friendly “soundbites” or as mass-produced library music for films and presentations?) As you can see from my thoughts on my film music (above), I am on the fence, and I try to work on both levels when creating music. Where do you stand? I hearby throw the debate open…

Heard on the Edge of Dreams
Posted on January 6th, 2009 at 10:15 pm by admin

“Any tone can succeed any other tone, any tone can sound simultaneously with any other tone or tones, and any group of tones can be followed by any other group of tones… successful projection will depend upon the contextual and formal conditions that prevail, and upon the skill and soul of the composer.”

- Vincent Persichetti “Twentieth Century Harmony”

By exploring harmonies that sit in the boundaries of our vocabulary, a rich new of world of chords with unique syntactical and expressive qualities can be found.

Varitations in chord density, range, simplicity / complexity are all equally important. Differing acoustics and instrumentation can radically alter our perception of intervals and chords as we may have become accustomed to them on the keyboard / guitar.

In the following fragment for brass choir, strings and percussion, simultaneous harmonic and melodic layers, as well as distortions of conventional harmonic colours all add to the overall sense of tonal contradiction. The process is hard to describe as I largely rely on my ear during composition, and I’m here I’m trying to convey a particular feeling that lies just beyond conventional description. The brass parts are shown in condensed score here (Pdf).

Using the “Giant Steps” Sound…
Posted on December 31st, 2008 at 5:29 pm by admin

We interupt this post to bring you some music:

<<< CLICK HERE FOR COMEDY INTERLUDE >>>

The hipster has just demonstrated another sound that I am quite fond of. For a given tonality, (say C dorian), try alternating between three key centres a major third apart, (say C dorian, E dorian, Ab dorian).

This kind of suggests the “Giant Steps” sound, which is:

Ebmaj7 F#7 | Bmaj7 D7 | Gmaj7 Bb7 | Ebmaj7 (Descending in major)

Same kind of idea, but ascending in minor…

Cm7 | B7 | Em7 | Eb7alt | Abm7 | G7alt | Cm7

The result is a sound of harmonic dislocation that I find quite pleasing in certain contexts. As ever, its important to judge the correct moment to use and idea, and to try and integrate it into whatever has taken place before and after it.

Rather that thinking in terms of shifting key centres, it is also possible to construct artificial scales out of these symmetrically displaced triads. The combination of Cm, Em and Abm triads yields this interesting scale combination that contains interesting patterns of intervals. Once again, used sparingly, this could be the source of some interesting tonal colours (pianists will have to think about the role of appropriate chord voicings and how they could be used in this context).

C Eb E Gb G Ab B

GEEK MOMENT - this scale is the same if you use C, E and Ab major OR C, E and Ab minor triads…)

The combination of three major triads a maj 3rd apart is also called the augmented scale, and has been described in “The Augmented Scale In Jazz” by Walt Weiskopf and Ramon Ricker.

This opens out a whole new spectrum of harmonic possibilities that were mapped out by Nicolas Slonimsky in “A Thesaurus of Scales and Melodic Patterns”. Whilst I am only vaguely familiar with the book itself, I occasionally try to apply some of these ideas when improvising.

What is Practice?
Posted on December 31st, 2008 at 5:08 pm by admin

I dislike the idea of piano practice as some kind of “keep fit”. The idea of making good music on the piano has nothing to do physical strength. I admit that I cannot play my scales “well” but its just not something that is top of my list of priorities. For this reason, I rarely teach piano technique as such. I am more interested in ergonomics applied to the keyboard. The time is better spent eliminating sources of tension so that the player has more chance to play without the inhibition of ideas through supposed “technical difficulty”.

I also dislike the idea of practicing as “shredding”. Quite simply, as an improvising musician, I never seem to gain anything by doing it. The brain has to learn to freely manipulate these shapes and ideas in real time, not reading them off a page. If you are having trouble “getting the fingers to work” in this cold weather - I would suggest some simple body stretching exercises about 10 minutes before the gig. You will look like an idiot :-) , but it really does help start the blood flow to the arms and fingers and gets the relevant tendons ready for action.

I try to practice “improvising” by experimenting with new ideas and colours in the context of tunes/grooves and trying to get myself into the mindset of flowing improvisation as fast as possible. Sometimes, if there is new material, I work on learning it. Otherwise, I’ll rather be writing some code or something… One thing I do like to do is to practice playing in very slow time over a form, giving me time to try and catch the melodic ideas “in my head” rather than falling into the patterns.

Six Note Scales (Hexachords)
Posted on December 31st, 2008 at 4:57 pm by admin

When I refer to six-note-scales, these are basically major scales with the 4th degree (“avoid note”) missing. You will hear these scales a great deal in celtic folk music and a great deal of jazz music from 1970 onwards…

EXAMPLE (mp3)

Eg: C, D, E, G, A, B

GEEK MOMENT - G,A,B,C,D,E - its intervalically symmetrical around the axis of B-C…..? Interesting?

Jazz musicians often play a chromatic passing note on the b5th degree of the scale making an 8-note run (fits the rhythm of the bar better?). This is referred to as the “bebop” scale, by folks who have dark glasses and berets. However, in this day of polished new-age sheen I often want to respect the diatonic purity of the underlying harmony, so I would rather remove a note from my seven note scale scale so that I have an even number of (six) notes.

Six Note Scales (Pdf)

I like the sound of these scales very much, especially when I want to play flowing lines over a very diatonic harmony, for example on a ballad or a folk tune. Not only is the fingering very easy on the piano, but you also have the advantage that it is a lot easier to end on a “strong note” when you need to, compared to conventional seven note scales.
