Sort alternate .abc in subdir 'Compact' under the booke dir. Use that as
the graphic for A5 output, assuming it will be vertically more compact.
Use Bear Dance as an example, as it has commentary that currently
overflows an A5 landscape page.
For the moment, transposed Bookes don't transpose and so don't use Compact.
Jane says: Am most comfortable between the bottom G (the bottom line of the bass clef) and top D (the note above middle C), but can play from bottom C upwards (the C string is a bit growly) and at a push can get as high as the A above middle C.
Implement the following rule:
1. If range is G to d', transpose down 2 octaves.
2. If lowest note is < C, transpose down 1 octave.
3. Otherwise calculate the distance above d for the highest note on a one
octave transposition, and the distance below G on a two octave
transposition. Find the smallest, and use the corresponding
transposition.
