In Indian classical music and dance, ‘Laya’ means tempo or speed.
There are three basic types: Vilambit (slow), Madhya (medium), and Drut (fast).
Vilambit Laya refers to a very slow, steady tempo that allows for detailed elaboration.
It is mostly used in the starting section of a performance to build mood and depth.
Hence, Vilambit Laya indicates a slow speed.
