What is "murki"

Murki is a short taan or inverted mordent in Hindustani classical music, known as pratyahatam in Carnatic music. It is a fast and delicate ornamentation or alankar, employing two or more notes and is similar to a mordent or ulta murki. It is often delivered in rapidfire tempo, and is employed in thumris and other lighter genres. Other taans used in thumri gayaki include the khatka and the zamzama.

This is also sometimes called Harkat or Jaga.
