Part 4 · Rock Grooves · Chapter 59
Drummers use the crash cymbal to mark the start of new sections: verse, chorus, bridge. The crash is almost always played together with the bass drum on beat 1.
Crash on beat 1 of the first bar, then back to the hi-hat.
A snare on the & of 4 sets up the crash in the next bar.
Listen to a song and count the bars of each section. Most sections are 4, 8 or 16 bars long. Crash where the new section starts.
