Music 680: Special Topics in Music - Interactivity and Improvisation (Spring 2007)
Class 5: February 21, 2007
assignment 3 due February 28
use fiddle~ and/or env~ to write data to arrays
and then use that data (after the fact) to generate some kind of musical response
again, not simple playback, but something based on analysis
audio installation (David Dinnell)

enumerating the qualities of instruments
balance: challenge, frustration, boredom
playability, progression, learnability
efficiency (complexity of output compared to complexity of input)
and the notion of performer freedom to complicate this idea
freedom of movement vs. freedom of choice
output diversity: stylistic, performance, expressive levels of abstraction
insistence upon improvisation as a quality of a musical instrument....
relationship between virtuosity and reproducibility in an expressive context....
as opposed to situations of nonlinearity and unpredictability
”confidence” as a measure of performative quality in this situations
is the performer the master of any nonlinearities? (at some kind of meta-level)
data processing
windowing
as a crude replacement for (or first step towards) phrase segmentation
moving averages
as a measurement of “drift” or evolution; continuity vs. contrast
histogram
a kind of representation which is itself a kind of analysis
classifying and counting events
thinning
the problem of too much data: rate-limiting
the problem of spurious data: “barrier” algorithms
discarding events below a duration threshold
discarding octave leaps
