Some basic thoughts on note numbering.
a Note is a Frequency; ie A440
A880 is the A note an octave above A440 ie frequency doubles
On a piano, the lowest note is an A; often piano players call it A1
In that case, A1 (name) is A55 (frequency).
Notice that the frequency description of a note sounded is not
arbitrary; a plucked string has a fundamental frequency, which
we use to describe the sound.
Western music notation is based on the idea of note names; ABCDEFG
A1, A2, ... are octaves apart. Note that 1 2 3 ... in these names
are arbitrarily assigned. We could (and I think some do) call
A440 A0. In that case the A an octive below would be called A-1, and
it would make prefect sense as long as folks knew what A0 was.
In brief, the numbers in note names are arbitrary and based on a
logarithmic scale of frequencies. Where the zero point is on that
scale is where the midi note numbering confusion arises. And the
confusion exist for instrument players in general.
> sane default, there are musically appropriate reasons for variations
I strongly agree. Isn't that just saying that an instrument should be
tune-able. Horns have tuning slides; guitars have pegs. My soundcard
has the capability; software that claims to support it should have a
tuning slider, peg, widgit, command or something.
