You can play ten different notes with PIP, the same as the first notes people learn to play on the recorder.
The notes are:-
To play several notes to make a tune, press and a number for each note. All the notes are the same length and there are no pauses between them. Most tunes will sound better if some of the notes are made longer (perhaps two or three times as long) and some pauses are put between them. To get longer notes just enter the same note several times.
Full details of how to program PIP to play tunes are in the PIP song book.
