monz - Tonescape presentation on Ben Johnston music, at Microfest on 4/15

Hello all,

I haven't been keeping up with any of the tuning lists lately,
but since the date is coming up soon, i just wanted to post
another announcement about this:

I'll be using Tonescape to give a presentation on the music
and music-theory of Ben Johnston, as part of the Microfest 2006
symposium dedicated to Ben's work as tribute for his 80th birthday.

http://www.microfest.org/microfest20063.html

date: this Saturday, April 15, 2006
time: starts at 12:00 noon
place: Boone Hall, Music Department, Scripps College,
Dartmouth and 10th, Claremont, CA

Below is the abstract of my presentation:

Ben Johnston's multi-dimensional extended-JI,
modeled in Tonescape software

by Joe Monzo

ABSTRACT

Ben Johnston devised a form of extended-JI (just-intonation)
which represents pitches as perfectly-tuned small-integer
frequency ratios. His earliest JI compositions used an
extended 1-dimensional pythagorean 3-limit system (i.e.,
ratios using prime-factors of only 2 and 3), then he progressed
to an expanded version of "classic" 5-limit JI, then in subsequent
works to higher and higher prime-limits. His most recent
compositions use all prime-factors up to 31. In Johnston's
music, as in most music, prime-factor 2 is considered to be
the "equivalence-interval". Tonescape software models
tuning systems as iterations of generators, with each generator
in its own dimension. Tonescape can model tuning systems
of up to 7 dimensions, thus, leaving prime-factor 2 out of the
Lattice diagram, in 7 dimensions it can model 19-limit JI.
Tonescape shows a Pitch-Height score in real time, and
also highlights the notes being playing on the Lattice in real time.
Some movements from Johnston's string quartets are presented
as example Tonescape files.

Perhaps you should say what Tonescape is. Also, the
phrase "Tonescape software" sounds plural here.

>tuning systems as iterations of generators,

This seems unclear.

>with each generator in its own dimension.

Each iteration? Or are there different generators?

What's a Lattice?

Howabout "using this visualization" for the bottom line
here?

Can you record it on video and put it on youtube? :)
