Metric levels: beat level shown in middle with division levels above and multiple levels below.

In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level[1] (or beat level).[2] The beat is often defined as the rhythm listeners would tap their toes to when listening to a piece of music, or the numbers a musician counts while performing, though in practice this may be technically incorrect (often the first multiple level). In popular use, beat can refer to a variety of related concepts including: tempo, meter, specific rhythms, and groove.

Rhythm in music is characterized by a repeating sequence of stressed and unstressed beats (often called "strong" and "weak") and divided into bars organized by time signature and tempo indications.

Metric levels faster than the beat level are division levels, and slower levels are multiple levels. See Metric structure. Beat has always been an important part of music.

Downbeat and upbeat

Beginning of Bach's BWV 736, with upbeat (anacrusis) in red. <phonos file="Anacrusis-bwv736.mid">Play</phonos>

The downbeat is the first beat of the bar, i.e. number 1. The upbeat is the last beat in the previous bar which immediately precedes, and hence anticipates, the downbeat.[3] Both terms correspond to the direction taken by the hand of a conductor.

An anticipatory note or succession of notes occurring before the first barline of a piece is sometimes referred to as an upbeat figure, section or phrase. Alternative expressions include "pickup" and "anacrusis" (the latter ultimately from Greek ana ["up towards"] and krousis ["strike"/"impact"] through French anacrouse). The latter term was borrowed from the field of poetry, in which it refers to one or more unstressed extrametrical syllables at the beginning of a line.[3]

On-beat and off-beat

Off-beat or backbeat pattern, popular on snare drum[4] <phonos file="Backbeat pattern snare drum.mid">play</phonos>
File:Skank on Em64.png
"Skank" guitar rhythm[5]<phonos file="Skank on Em64.mid">Play</phonos>. Often referred to as "upbeats", in parallel with upstrokes.

In music that progresses regularly in 4
4 time, counted as "1 2 3 4, 1 2 3 4...", the first beat of the bar (downbeat) is usually the strongest accent in the melody and the likeliest place for a chord change, the third is the next strongest: these are "on" beats. The second and fourth are weaker—the "off-beats". Subdivisions (like eighth notes) that fall between the pulse beats are even weaker and these, if used frequently in a rhythm, can also make it "off-beat".[6]

The effect can be easily simulated by evenly and repeatedly counting to four. As a background against which to compare these various rhythms a bass drum strike on the downbeat and a constant eighth note subdivision on ride cymbal have been added, which would be counted as follows (bold denotes a stressed beat):

  • 1 2 3 4 1 2 3 4 —<phonos file="Backbeat example eighth notes.mid">play eighth notes and bass drum alone</phonos>
  • 1 2 3 4 1 2 3 4—the stress here on the "on" beat <phonos file="Backbeat example unsyncopated.mid">play</phonos> But one may syncopate that pattern and alternately stress the odd and even beats, respectively:
  • 1 2 3 4 1 2 3 4 —the stress is on the "unexpected" or syncopated beat <phonos file="Backbeat example.mid">play</phonos>

So "off-beat" is a musical term, commonly applied to syncopation that emphasizes the weak even beats of a bar, as opposed to the usual on-beat. This is a fundamental technique of African polyrhythm that transferred to popular western music. According to Groove Music, the "Offbeat is [often] where the downbeat is replaced by a rest or is tied over from the preceding bar".[6] The downbeat can never be the off-beat because it is the strongest beat in 4
4 time.[7] Certain genres tend to emphasize the off-beat, where this is a defining characteristic of rock'n'roll and Ska music.

Backbeat

"Backbeat" redirects here. For other uses, see Backbeat (disambiguation).
Back beat[8][9] <phonos file="Backbeat chop.mid">Play</phonos>
"It's got a backbeat, you can't lose it" – Chuck Berry, "Rock and Roll Music"

A back beat, or backbeat, is a syncopated accentuation on the "off" beat. In a simple 4
4 rhythm these are beats 2 and 4.[10]

"A big part of R&B's attraction had to do with the stompin' backbeats that make it so eminently danceable," according to the Encyclopedia of Percussion.[11] An early record with an emphasised back beat throughout was "Good Rockin' Tonight" by Wynonie Harris in 1948.[12] Although drummer Earl Palmer claimed the honor for "The Fat Man" by Fats Domino in 1949, which he played on, saying he adopted it from the final "shout" or "out" chorus common in Dixieland jazz, urban contemporary gospel was stressing the back beat much earlier with hand-clapping and tambourines.[citation needed] There is a hand-clapping back beat on "Roll 'Em Pete" by Pete Johnson and Big Joe Turner, recorded in 1938.[citation needed] A distinctive back beat can be heard on "Back Beat Boogie" by Harry James And His Orchestra, recorded in late 1939.[13] Other early recorded examples include the final verse of "Grand Slam" by Benny Goodman in 1942 and some sections of The Glenn Miller Orchestra's "(I've Got A Gal In) Kalamazoo", while amateur direct-to-disc recordings of Charlie Christian jamming at Minton's Playhouse around the same time have a sustained snare-drum back-beat on the hottest choruses.[citation needed]

Outside U.S. popular music, there are early recordings of music with a distinctive backbeat, such as the 1949 recording of Mangaratiba by Luiz Gonzaga in Brazil.[citation needed]

Delayed backbeat (last eighth note in each measure) as in funk music[14] <phonos file="Delayed backbeat.mid">play</phonos>

Slap bass executions on the backbeat are found in styles of country western music of the 1930s, and the late '40s early '50s music of Hank Williams reflected a return to strong backbeat accentuation as part of the honky tonk style of country.[15] In the mid-1940s "hillbilly" musicians the Delmore Brothers were turning out boogie tunes with a hard driving back beat, such as the No.2 hit "Freight Train Boogie" in 1946, as well as in other boogie songs they recorded.[citation needed] Similarly Fred Maddox's characteristic backbeat, a slapping bass style, helped drive a rhythm that came to be known as rockabilly, one of the early forms of rock and roll.[16] Maddox had used this style as early as 1937.[17]

In today's popular music the snare drum is typically used to play the backbeat pattern.[4] Early funk music often delayed one of the backbeats so as "to give a 'kick' to the [overall] beat".[14]

Some songs, such as The Beatles' "Please Please Me" and "I Want to Hold Your Hand", The Knack's "Good Girls Don't" and Blondie's cover of The Nerves' "Hanging on the Telephone", employ a double backbeat pattern.[18] In a double backbeat, one of the off beats is played as two eighth notes rather than one quarter note.[18]

Cross-beat

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

Main article: Cross-beat

Cross-rhythm. A rhythm in which the regular pattern of accents of the prevailing meter is contradicted by a conflicting pattern and not merely a momentary displacement that leaves the prevailing meter fundamentally unchallenged—New Harvard Dictionary of Music (1986: 216).[19]

Hyperbeat

A hyperbeat is one unit of hypermeter, generally a measure. "Hypermeter is meter, with all its inherent characteristics, at the level where measures act as beats."[20] Further reading: Rothstein, William (1990). Phrase Rhythm in Tonal Music, p. 12-3. Macmillan. ISBN 978-0028721910.

  • Tatum refers to a subdivision of a beat which represents the "time division that most highly coincides with note onsets".[21]
  • Afterbeat refers to a percussion style where a strong accent is sounded on the second, third and fourth beats of the bar, following the downbeat.[10]
  • In Reggae music, the term One Drop reflects the complete de-emphasis (to the point of silence) of the first beat in the cycle.
  • James Brown's signature funk groove emphasized the downbeat – that is, with heavy emphasis "on the one" (the first beat of every measure) – to etch his distinctive sound, rather than the back beat (familiar to many R&B musicians) which places the emphasis on the second beat.[22][23][24]

In February 1965, with "Papa's Got a Brand New Bag," he decided to shift the beat of his band: from the one-two-three-four backbeat to one-two-three-four. "I changed from the upbeat to the downbeat," Mr. Brown said in 1990. "Simple as that, really."

According to Maceo Parker, Brown's former saxophonist, playing on the downbeat was at first hard for him and took some getting used to. Reflecting back to his early days with Brown's band, Parker reported that he had difficulty in playing "on the one" during solo performances, since he was used to hearing and playing with the accent on the second beat.
