These exercises are great for putting together drum beats and drum fills, like they might appear in a song, although usually there are more drum beats than fills in a song. These exercises have a 1 bar drum beat and 1 bar of a fill, so that each type is practiced equally.

The drum fills are ideal for those playing drum fills for the first time. The drum beats are quite hard for complete beginners, so some experience of playing them first is recommended before mixing them with the fills, which are a bit easier than the drum beats.

One thing that could be a stumbling block to playing the drum fills, is reading the drum notation and knowing which lines of the staves the toms are on. Here is a useful reference sheet for this: Reading Drum Notation.
