What does a composer do when he wants a musician to play a note on the "and" of a count, but not on the "number"? Well, one solution is to throw away the first eighth note in a group of two eighths (the rhythm covered in the last lesson) and replace it with an eighth rest. Since the eighth rest has the same value as an eighth note, any eighth note could be replaced by an eighth rest. Since the eighth note stands alone on the second half of the beat, it is written with a flag instead of a beam.

Examples A and B show the two figures that result when each of the two eighth notes in a count is replaced by an eighth rest. To perform example A, count the number (but, don't play it), and strike the drum on the "and" count. To perform B, do the opposite and only play on the number count.

Figure B sounds the same as the quarter note when you play it on a drum. But, keep in mind that rests actually signify a certain duration of silence and for this reason, the two figures are not quite the same. If you were playing a wind or string instrument, then you would stop the sound when you came to the rest. Since most drums do not have a very long duration, these figures sound pretty much the same and you don't need to worry about stopping the sound. If you want to have some fun, try playing these exercises on a suspended cymbal. You can then observe the eighth rests by reaching up and grabbing the cymbal with your hand in order to muffle the vibrations and create the required silence.

Before moving on to 16th notes, try your hand at performing the following exercise:
