Six Linear "Skeleton" Drum Fills
The term "Skeleton," in drumming, refers to drum parts that use only the snare, bass, and cymbals. In other words, no toms or other drums are used. If you see a drum kit with only snare, bass, and cymbals, you could call it a skeleton setup (or skeleton kit).
Beats 1 and 2 of each drum fill (i.e. the first half of the fill) are repeated for beats 3 and 4 (i.e. the second half of the fill). After learning these fills, try mixing the halves from the six fills to create new fills.
