Converting pitches into numbers should just be ly:pitch-semitones which
has existed for eternities.  There is also ly:pitch-tones which becomes
useful when you are juggling with microtonalities and thus have to work
with exact rationals.  ly:pitch-semitones always converts to integers
and thus loses the fine distinctions.
