Pattern 05

The trap drum pattern

A trap beat is counted in half time. The clap falls once a bar, on beat three, over a few kicks and hats in steady eighths broken by fast rolls. The usual tempo is 140 BPM, felt as 70.

Half time

Set the tempo to 140 and the clap lands on step 9, the third beat. Heard on its own, that one clap a bar feels like a backbeat at 70 BPM. The fast grid is there for the hats: sixteen steps at 140 leave room to subdivide them.

The rolls

On a record a roll is three 32nd notes, or faster, in place of one hat. Beep Boop's steps are sixteenths, so these figures play two hats where the roll would be, on steps 7 and 8. They mark the place of the roll. They are not the roll.

Tempo

Typically 140 BPM, written as 70 when it is counted in half time. Published ranges run from 130 to 145.
