Hi matt -

Well, I did an experiment, just putting a major scale in (key of C),
and when I transpose it to D flat, half the notes are wrong. And more than half
don't even get played. These are all quarter notes in 4/4 time.

I don't have ANY objection to having double flats or sharps, but they should be CORRECT.

For example, the key signature for A# only has one double sharp, rather than 3
like it should, and that's in the wrong place. The double sharps should be on F, G, and A.
So the total number of sharps should be 10. (3*2 + 4)

When transposing any melody, there are three things that have to match:

(1) the number of accidentals are exactly the same.
(2) When the accidental RAISES the note 1/2 step, the accidental in the new key does the
same thing.
(3) When the accidental LOWERS the note 1/2 step, the accidental in the new key does the
same thing.
(4) The line spacing between successive notes is unchanged. In other words, if two notes are a
space apart, they remain that way in the new key. Likewise for a line apart, etc.

Well, maybe someone should have that choice of weird keys. But doesn't it have to be correctly done?
