2008 – Alto Saxophone or Viola and Pure Data – Nate Bliton

I wrote this for my friend Shawn Teichmer and it has developed into what is my first fully-fledged piece for a separate performer and electronics.

Notes:

With this piece, I wanted to take effects and compositional devices commonly found in classical and popular electronic music, and employing them in real time.  Maybe my favorite compositional device in electronic music, cutting up a recording and reassembling it, in a different order, in a rhythmic figure, or to create a new texture, is easy to do on a computer with audio editing software (if time-intensive), but it would be very difficult to move one’s mouse fast enough and with such accuracy to be able to “play the computer” along with another musician in a performance.  This Pure Data patch plays this part, sampling the musician’s playing through out the piece for later use, applying reverb and pitch-shifters, and taking turns following and leading the musician, as the score dictates.  The computer is listening for pitches and rests to know where in the score the musician is playing and how fast the musician is taking the piece, and accordingly follows a list of instructions dictating when to record, when and at which tempo to play back and when to apply different effects to the musician’s amplified sound.  All of the sounds played by the computer come from the performer over the course of the piece, and can be played by any instrument capable of playing the range of pitches dictated in the musician’s part of the score.
