the most logical in this matter to me would seem to be the use of numbers.
suppose the frequency of the tone to be named is f, choose a reference
frequency F, thus a=lb(F/f) would be a convenient measure, lb() being the
binary logarithm. presuming F=440 1/s to be the default reference frequency
that makes:
note a
- ------------
A 0
A# 0.0828
B 0.1640
C 0.4293
.
.
A' 1
A#' 1.0828
B 1.1640
.
.
the main advantages are that, to move to a differen octave simply add whole
numbers, and this scheme does allow for notes not part of the dodecaphonic
scale. unfortunately at the moment i can not come up with an easy way to
express this in lojban, except for a new gismu like
x1 is a note with x2=a, x3=F and x4=f (F= 440 1/s by default)
