The breakdown in the metal and hardcore punk genres is where a band will usually play in half time, giving the feeling of a slower tempo. It is considered by some to be an important element in many songs of these genres and central to many bands, quite a few of which eschew traditional verse-chorus-verse songwriting. When played live, breakdowns are usually responded to by the audience by moshing or hardcore dancing. 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. Many metalcore bands rely on having memorable breakdowns rather than memorable choruses.
The drums are usually simple with several cymbals and snare on the third beat. The cymbals are usually a china or fast crash with quarter notes or more common, eighth notes. Also common is the use of crash cymbals with quarter notes, or even half notes, to give the music a very heavy, slow feel. The drummer usually follows the rhythm of the guitar on the kick drum. In metal, 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, or pinch harmonics. These riffs are often accented by the drummer with double kick bass drums that follow the pattern of the guitars. This kind of breakdown can be traced back to the Los Angeles thrash metal band Dark Angel, whose drummer Gene Hoglan first played this kind of rhythmic double bass drums-guitar oriented breakdown on the title track of Dark Angel's second album, Darkness Descends. Gene Hoglan has used this technique, which he calls 'kick triplets', in various bands in which he played since then, and it had become commonly used in Thrash Metal and especially Death Metal, although not always in the same way it is used in Metalcore.
