* In physics and sound, a beat is the oscillation between zero intensity and full intensity that occurs when two frequencies (which are not harmonically related) are added together, caused by alternating constructive and destructive interference of the pressure waves. Beating is heard as a pulsation in loudness of two nearby frequencies, f1 and f2, at the rate of |f1 − f2|. Thus f = 0 when the two waves are in unison and as the difference between f1 and f2 increases, the speed increases until beyond a certain proximity beating becomes undetectable and a roughness is heard instead, after which the two pitches are perceived as separate. Beating can also be heard between notes that are near to, but not exactly, a harmonic interval. The composer Alvin Lucier has written many pieces which feature interference beats as their main focus. Musicians commonly use interference beats to objectively check tuning at the unison, perfect fifth, or other simple harmonic intervals. (See also heterodyne.)- In music, beat is any of the periodic transient signals in music that mark the rhythm.
- Beat can also mean solely the bass and snare drums of the rhythm. DJs often beatmatchBeatmatching is a mixing technique employed by DJs. While originally it involved counting the tempo with a metronome and finding a record with the same tempo, today it involves changing the speed at which a recording is played back so that its tempo match the songs that they play.
- Interference beats are used in tuning, see tuning and physics above.
