Our second rock groove is called "Cash" and is reminiscent of one of the great Pink Floyd basslines. This groove is in 7/4 time, which may be a little tricky if you've never played "odd time" grooves before. It's good practice to actually count the beats out loud as the play the bassline for the first few times. The 7/4 groove is divided into two sections, first with a 5 beat phrase and ending with a 2 beat phrase. Be sure to emphasize this when you play the part! Playing this bassline with a pick will also help you get that Pink Floyd sound.
