After having been asked by a few people if I have a mailing list for sonic art/music events I am doing, I have finally got into gear and set one up. So if you would like to subscribe to it and hear what is going on that would be great! I promise I wont spam you and you can unsubscribe at any time.
Ricercar was created as a way to create evolving polyphonic textures in a ‘solo’ violin piece. It uses a midi foot controller (currently a Behringer FCB1010) to control an electric violin into a piece of software created specifically for this piece.

The work is essentially fugal, relying on live sampling to create the layers around the instrumental part and uses a 3 layered sequencer to achieve this. Each layer contains a series of buffers which can be recorded into. The top layer has seven 5 second samples, the middle has 5×17 and the lower has 3×71 second samples. These all prime durations so when left to their own devices they will take a long time to ever repeat in precisely the same configuration. Using a foot controller to trigger when to start recording and which buffer to record to or overwrite, thus it is possible to gradually build up a four part texture using the three sampler ‘lines’ and the live violin.
Overlapping prime blocks 5,17 and 71
In itself this is passable, but could be rather recursive and very quickly get repetitive unless loops are overwritten regularly, which in itself could become an oft-repeated task. This has been overcome in 2 ways. The first is that each time a sample is due to be played there is a 50% chance that it will not be in which case the sequencer just moves on and waits until the next step is ready and then re-rolls its virtual dice. When scaled up over each of the 3 layers of fast, medium and slow samples this means that there will probably always be something playing (depending on how many samples have had audio recorded into them!) but the thickness of the texture will vary. The second way that diversity is added is by changing the playback speed of each sample. As a sample is triggered the sequencer takes a decision as to what pitch/speed to play the audio. This varies over four octaves (two up and two down) and results in a shift in playback of between quarter speed and four times as fast. The speed changes are in discrete even tempered steps and thus a broader sense of harmony and polyphonic/contrapuntal line can be achieved.
In addition to this audio focused processing there are 2 global controls. The first is how fast the sequencer triggers each step. This in itself does not affect the length of individual samples so at extreme speeds loops will overlap in a densely fired texture or conversely there may be a lot of space and silence at very slow speeds. The last of the controls is volume of playback, which when used carefully can not only help to balance the live and processed material but can greatly increase the sensation of articulation and dialogue.
Within this framework the performer is free to improvise, guided by the constraints and freedoms of the instrument, themselves the hardware and software.

Sadly due to very poor weather the Magic Toy Forest event (and therefore the Xmas-o-lo-phone which was my contribution) has had to be cancelled. A massive thanks to all who have worked so hard to get such a big collaborative project to this point. Hopefully it will happen somewhere soon!
I’m going to set up a Christmas ‘xylophone’ between the trees. This will consist of a series of hollow (tuned) pipes hung length ways between the trees, suspended on rope or chord. The overall effect will look similar to a rope ladder slung sideways.
The idea is that rather than just playing a scale it will play Jingle Bells. So, the first few notes will be at the same pitch as with the tune:
Jingle bells, jingle bells
Jin- (It is not until you get to note 8 that it rises in pitch!)
So, each rung is a note of the tune, as you run along blowing or tapping them they play the tune, they will also be spaced so that the rhythm works properly e.g. the third note has twice as big a gap to the next ‘rung’ compared to the previous note.
It would be good to set it up in a horseshoe (probably more realistically a V) shape between the trees so that is can be run around in a loop.
The trick is working it out so that it is dead easy to play.
|Step||Pitch||Rhythm||Degree of scale||Relative pipe length||Pipe length in (mm)||Cut from pipe batch||Relative distance to next note||Distance to next note (cm)|

A Brief Intro to Acousmatic Composition
Posted elsewhere but may be of some interest!
“Our musical alphabet must be enriched. We also need new instruments very badly. . . . In my own works I have always felt the need of new mediums of expression . . . which can lend themselves to every expression of thought and can keep up with thought.”
Edgard Varèse: New York Morning Telegraph 1916
“Perhaps the time is not far off when a composer will be able to represent through recording, music specifically composed for the gramophone”
Andre Coeuroy: Panorama of Contemporary Music 1928
“The rediscovery of the musicality of sound in noise and in language, and the reunification of music, noise and language in order to obtain a unity of material: that is one of the chief artistic tasks of radio.”
Rudolf Arnheim Radio 1936
“When I proposed the term ‘musique concrète,’ I intended … to point out an opposition with the way musical work usually…

Working writing some music for the wonderful No Fit State Circus (see one of their videos above-not my audio though), based upon a set of poems written by school kids for the opening of the new arts centre in Bangor, Wales. Getting the work done means I get to see a lot of this as it means a lot of early starts.

However it does mean that I get to work with a fantastic set of people in what promises to be an amazing new venue. The building isn’t built yet so I’m not to stressed but hey September is going to arrive quickly!
Gosh I forgot how tiring it is being productive! 🙂
Here is some stuff I put together a while back. It may be useful for some people 🙂

What is Max/MSP?
Max/MSP (often just called ‘Max’) is a ‘multimedia programming environment’ which will allow you to create pretty much any kind of music or audio software you can think of. It can also handle video using a built-in extension called ‘Jitter’.

Going out to go underwater sound recording for Bangor New Music Festival 🙂
As I have been traveling everywhere by bus this week, which given the nature of what I do is not always that simple given the amount/delicate nature of kit that goes about the stuff in the box has become stripped down to the level of an art in itself…..
2 x hydrophones (lent by Bangor Uni School of Ocean Sciences)
1 x Fostex audio recorder
1 x remote control in case of wet situations
1 x headphones
1 roll of insulation tape for insulation, table tidying, and waterproofing.
1 roll of surgical tape for attaching things to people if required
1 roll of gaffa tape for almost anything
1 roll of aluminum tape for conductive and heat proof repairs
1 x multimeter to mend stuff when it breaks
25 x nappy bags for inexpensive waterproofing.
1 spoon for banging things to make noise
1 feather to ‘silently’ make tings make noise
Fishing line for suspending things
Balloons for suspending things in the water column.
Absolutely nothing that requires mains power!
‘Tis going to be great and mad, especially when there are 26 primary school kids all armed with microphones thrown into the mix too!
After roughly 5 years, I am relocating my studio out of Hendre Hall to closer to home. There have been some great times there and I’d like to say thanks to all who have supported, listened and heckled over the years. Especial thanks must go to Malcolm and James Innes along with Mike ‘The Lights’ for putting up with the strange noises and random happenings. A massive thanks to everyone 🙂
I have had loads of fun there and created some cool things, even if I do say so myself! From: instrumental music, motion tracking party installations, through to surround sound acousmatic pieces, electronics and programing, and sonic marble runs I have had a blast.
All these have made in some way in that studio.
