Drum beat

This article is about many hits together. For one hit, see drum stroke. For marching hit patterns, see drum cadence.

A drum beat or drum pattern is a rhythmic pattern, or repeated rhythm establishing the meter and groove through the pulse and subdivision, played on drum kits and other percussion instruments. As such a "beat" consists of multiple drum strokes occurring over multiple musical beats while the term "drum beat" may also refer to a single drum stroke which may occupy more or less time than the current pulse. Many drum beats define or are characteristic of specific music genres.

Many basic drum beats establish the pulse through alternating bass (on the on-beats) and snare drums (on the off-beats) strokes while establishing the subdivision on the ride cymbal (thus its name) or hi-hat:

Simple quadruple drum pattern, "Straight blues/Rock groove": divides each of two beats into two <phonos file="Simple duple drum pattern.mid">Play</phonos> or <phonos file="Characteristic rock drum pattern rimshot.mid">Play with rimshots</phonos>

This establishes a quarter note pulse in (quad)duple time: each measure is formed from (two groups of) two quarter note pulses, each pulse divided into two eighth notes.

Simple triple drum pattern: divides each of three beats into two

This establishes a quarter note pulse in triple time: each measure is formed from three quarter note pulses, each divided into two eighth notes.

Compound [quadr]duple drum pattern: divides each of two beats into three <phonos file="Compound duple drum pattern.mid">Play</phonos>.

This establishes a dotted-quarter note pulse in duple time: each measure is formed from two dotted-quarter note pulses, each pulse divided into three eighth notes.

Simple duple drum pattern but with triplets: divides each of two beats into three. <phonos file="Jazz triplet subdivision.mid">Play</phonos>

Compound triple meter is equivalent to simple duple meter with triplets on every beat.

Compound triple drum pattern: divides each of three beats into three <phonos file="Compound triple drum pattern.mid">Play</phonos>

This establishes a dotted-quarter note pulse in triple time: each measure is formed from three dotted-quarter note pulses, each pulse divided into three eighth notes.

A "fill" is played in between the regular strokes of a pattern and/or signals the end of a phrase:

Sixteenth note fill in a rock/popular groove played on a drum kit. <phonos file="Fill with groove number 2 and sixteenth notes.mid">play</phonos>

Since a phrase is multiple measures long, a fill signaling the end of one would come at the end of the last in a series of repeated measures.

In double and half-time patterns the pulse and ride are either doubled or halved, respectively, occurring twice or half as often:

Double-time: the snare moves to the "&" beats while the hi-hat begins to subdivide sixteenth notes.<phonos file="Double-time rock pattern.mid">Play</phonos> Also, the eighth notes 'sound like' quarter notes in two tiny measures.

Half time: the snare moves to beats 3 of measure one and two (beats 3 & 7) while the hi-hat plays only on the quarter notes. Also, the quarter notes 'sound like' eighth notes in one giant measure.

A blast beat drum pattern features all drums on the eighth note subdivision or variants with one or more drum's pattern displaced by a sixteenth note:

Blast beat drum pattern <phonos file="Blast beat drum pattern.mid">Play</phonos>.

Blast beat drum pattern <phonos file="Blast beat drum pattern 2.mid">Play</phonos>.

This resembles a combination of double-time (bass-snare pattern) and original time (ride pattern).

Delayed backbeat (last eighth note in each measure) as in funk music <phonos file="Delayed backbeat.mid">play</phonos>

Despite the difference in notation, there is no difference in interonset intervals and this pattern is nearly identical to the first simple duple pattern except for the second onbeat being divided into two eighth notes and of course the second backbeat being delayed an eighth note.

The heavy metal gallop, named for a horse's canter, is based on a bass drum pattern of one eighth followed by two sixteenths.
