 The sruti thus is the unit of measure or small difference between the various
Consecutive pitches within a grama or a scale. For all practical purposes they are said to be twenty two.
A characteristic contribution of India to musical rhythm is the tala. Tala is a cyclic arrangement of time units. The basic units of time division are laghu, guru, and pluta. These are actually derived from poetic prosody. Laghu comprises one syllable,guru two, and plutathree. There are also larger units. Bharata's Natya Shastra gives details of construction of tala out of various time units, how they should be played and so on. Later authors developed a scheme of 108 talas.
