In Indian classical music, a Matra[1] is a beat, the smallest rhythmic sub-unit of a tala - the musical meter.
It is one of the three levels of structure for tala[2] along with Vibhag (measure)[3] and Avartan (cycle).
[4] The significance of beats depends on their occurrence in a cycle.
However, the value of the beats may be stretched or contracted depending on various factors.
