The Transpose function makes it possible to shift the pitch of the entire keyboard up or down in
semitone intervals to facilitate playing in difficult key signatures, and to let you easily match the
pitch of the keyboard to the range of a singer or other instruments. For example, if you set the
transposition amount to “+5,” playing key C produces pitch F. In this way, you can play a song as
though it were in C major, and the NP-30/YNP-25 will transpose it to the key of F.
