What is the Ajrara gharana?

The Ajrara gharana, also spelt Ajrada, is a school of tabla that arose in the late 18th or early 19th century in the village of Ajrara, in Meerut district. Most accounts trace it to two brothers, Kallu Khan and Miru Khan, who learnt in Delhi, making it an offshoot of the Delhi gharana. Its players add the ring finger to the Delhi technique. It is best known for qaidas, themes with set variations, in aad laya, three strokes to every two beats. Ustad Akram Khan plays in the gharana today.
