Beats are the audible pulsations of an interval or unison.
A beat rate is the count of pulsations per second.
1 beat per second (bps) is equal to 1 Hz,which at A440 is approximately 4 cents. e.g.A439is1Hz flat, and A438 is 2 Hz flat or 8 cents flat.
A false beat is a pulsation in a single string, usually due to poor scaling or termination points in the string.
