Example 2

The same ones, played in a 3-bar sequence.

Example 3

The 3-bar ostinato, applied to other bass-drum patterns

The three-bar ostinato can also be viewed as being in 3/4 or 6/4 and played over 4/4:

16-bar Groove Exercise

This example is an application of this concept, to the first exercise of my Time Manipulation Drum Book.

Each pattern is played twice, but if you listen to the sound file, the hi-hat plays the previous shifting accents instead of the unaccented eighth-notes that are written.

This is Exercise 1 of my Time Manipulation Drum Book (page 25), played with Polyrhythmic Ostinato 1 (page 127). In this video example, I played each pattern 4 times, before moving on to the next.

Andy Newmark is a legendary drummer, and he played this shifting hi-hat part in a very creative and tasty manner.

There are two versions of this song, the first one was sung by Yoko Ono and there is also one which was sung by John Lennon.
