What does transpose mean
In music, to transpose means to change the key of a piece by shifting all notes up or down by the same interval.
Examples:
- Moving a song from C major to D major (+2 semitones).
- Lowering a jazz chart from Bb to Ab (–2 semitones).
Musicians transpose to fit their vocal range, adapt to different instruments, or practice in multiple keys.
