change occurs, you will need to figure that out if it isn't the
typical 1 and 3 beats.
An asterisk * indicates another measure of the same chord.
A slash / indicates that the bass note is different from the root
of the chord. E.g., Bb/Eb means the guitars play Bb, but the bass
player plays Eb. Sometimes the guitars will also play the alternate
bass note, sometimes not.
A tilde ~ indicates that you strum the chord once and let it ring.
