“Vocalists also tend to throw in a single, repeated statement throughout the breakdown, giving those who are not dancing or moshing an opportunity to sing along.
The drums are usually simple, with a four quarter-note ride pattern with the snare on the third beat. Most commonly, the drummer plays quarter notes on the crash cymbal or china cymbal. Sometimes though, eighth notes are used. In some breakdowns where a very slow tempo is used, the drummer will play half notes, to give the music a very heavy, slow feel. The drummer usually follows the rhythm, or “chugs” of the guitar on the kick drum. In most cases, the drummer will use a double-bass drum or double-bass pedal to complement the “chugs” of the guitars. The guitars play a set of rhythmically oriented riffs, usually on open strings so as to achieve the lowest and heaviest sound for which the guitars are tuned, so the dancers in the audience can respond effectively. Sometimes, these are contrasted with either dissonant chords, such as minor 2nd intervals, tritones (flatted 5ths), or pinch harmonics.
In punk rock, breakdowns tend to be more upbeat…”
