Art, analysis, audio.
My friend Sandy used nedwaves graphics for the opening and closing
credits on his documentary for Brookline Access Television, Never
2 Late 2 Play.
The film follows a group of jazz
musicians at the John Payne Music
School, many of whom started (or re-started) playing music as adults.
Pure tones are an abstraction-- all real-world sounds have bandwidth.
Bells make nearly-pure narrow sounds; drums make wide ones. How do we
measure interval ratios of notes with width?
I managed to put a couple of pieces together for this year's Punto y Raya
and they took this one:
This is a vertical
number line, labelled in seconds, showing event
durations. At the bottom are long-lasting musical patterns (sets,
concerts); at the top are quick events-- also called notes.
Formally, the chart title is "Duration
of events which, if repeated, humans can distinguish".
We're aware of lots of repeating patterns: with 100s of repeats per
notes; 100s per minute as rhythm; 100s per hours as verse.
The leftmost column is octaves (frequency doublings) away from 1
second. I suppose it could be
extended for ultra-long pattern repetitions, like "the radio played
song yesterday" or "this restaurant hasn't changed the soundtrack in
Fun fact: the range shown is almost the same as the Richter scale,
since 33 octaves=10 Richters. (10 octaves = 2^10 = 1024 ~= 1000
= 10^3 = 3 Richters)
Also: this chart covers the range (10^-5) seconds to (10^4)s.
A 2nd page would cover 10^4 to 10^13. A year is 32x10^6 seconds.
A 3rd page would cover 10^13 to 10^22. The age of the universe is
