Transpose function (Shifting the key)
In some cases, a song may be wrien in a dicult key (e.g., using many black keys), or
you may wish to shi the key to match another instrument or vocalist. In such cases,
you can transpose (shi the key) to use an easier ngering (without playing too many
black keys), or to use the same familiar ngering to play in a dierent key. This is
called the Transpose function. You can shi the key in a range of eleven semitones.
For example if you transpose upward by one semitone, playing the notes shown in the
upper score to the le will produce the pitches shown in the lower score.
•
To transpose the key, press and hold down the A
#
7, B7, and C8 keys, and press a key
from F
#

by three semitones), press and hold down the A
#
7, B7, and C8 keys, and press the
A2 key. If you wish to use the C3 key to play note D
#
