JFugue17. Chord progression from 2Pac's Changes (1998)

We play chord progression from 2Pac's Changes.

The pattern in patt1 is repeated twice. The tempo is set at 105. The dotted notes are indicated by putting a dot(.) after the duration such as q. for dotted quarter note. We have to be careful to put spacing between all tokens so they are properly parsed.
