Hi Tony,
There are a couple of different options you can do.
If you actually want the sound you hear (actual pitches) to be higher, you can use Staff/Transpose Pitches.
If it's something like guitar, which sounds lower than it's notated, you can use Staff/Transpose Instrument key.
There is a
tutorial video here which explains the difference, and shows you how to do both types.
ttfn,
Sherry
