Transpose function (Shifting the key)

In some cases, a song may be wrien i n a dicult key (e.g., using many black keys), or
you may wish to shi  the key to match another in strument or vocalis t. In such cas es,
you can transpose (shi t he key) to use an easier ngering (without playing too ma ny
black keys), or to u se the same familiar ngering to play in a dierent key. This is
called the Transpose function. You can shi the key i n a range of eleven semitones.
For example if you transpose upward by one semitone, playing the notes s hown 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#2 to B3 or from C#3 to F3. The name of the key that you pressed will become
the transposed key. For example, if you wish to use the C3 key to play note A2 (lower
by three sem itones), press and hold down the A#7, B7, and C8 keys, and press the
A2 key. If you wish to use th e C3 key to play note D#3 ( higher by three s emitones),
press and hold down the A#7, B7, and C8 keys, and press the D#3 key.
To reset the Transpose function to “No Transposition (+/-0),” press and hold down the
A#7, B7, and C8 keys, and press the C3 key.
The default seing (when you turn on the unit) is “No Transposition.”
