Usage
Usage: transpose N SOURCE.abc [DESTINATION.abc]
transpose KEY SOURCE.abc [DESTINATION.abc]
- Transpose ABC-format music by interval N.
- Transpose ABC-format melodies for KEY instrument.
If DESTINATION.abc is not supplied, output is written to standard output.
When interval N is a positive or negative integer (with no `.'), transpose
the melodies and chords upward or downward (respectively) by N semi-tones.
Fractions and numbers with decimal points specify `musical intervals':
Intervals Semi-tones Intervals Semi-tones
-1/2 -2. -2 1/12 12. 19
-1/3 -3. -4 1/11 11. 17
-1/4 -4. -5 1/10 10. 16
-1/5 -5. -7 1/9 9. 14
-1/6 -6. -9 1/8 8. 12 (1 Octave higher)
-1/7 -7. -11 1/7 7. 11
-1/8 -8. -12 (1 Octave lower) 1/6 6. 9
-1/9 -9. -14 1/5 5. 7
-1/10 -10. -16 1/4 4. 5
-1/11 -11. -17 1/3 3. 4
-1/12 -12. -19 1/2 2. 2
KEY may be A through G, optionally followed by sharp (#) or flat (b).
For example, "transpose Bb Reveille.abc" will produce ABC script with
notes appearing two semitones higher than in Reveille.abc.
Transpose strips out guitar-chords and turns lyrics into comments when
transposing for KEYed instruments. It may sometimes be neccessary to
"transpose +12" or "transpose -12" the result of transposing for an
instrument.
