One octave (variable) Jori, Jodi, Dhamma, or Jorhi (sometimes Jori-Pakhawaj) is a South Asian percussion instrument made up of two individual drums.
[1][2] Prominent exponents of the Jori include Ustad Sukhvinder Singh "Pinky".
[4] The Jori, Jodi, or Jorhi was first created by the 5th Sikh guru, Guru Arjun Dev Ji when 2 bards of his court, Satta and Balwand, wanted to separate the much older & venerable Pakhavaj into two instruments, similar to the tabla.
[5] Over a gradual period of time, and especially after the Partition of Punjab in 1947, most rabab players (which have historically been Muslim since the times of the first Sikh Gurus) emigrated to Lehnda Punjab, Pakistan, This took a way a key part of the Jori playing symphony, and the rabab was replaced with more canonically Indian instruments, such as the harmonium to replace missing melody.
A Qawwali Dhamma is lightweight, smaller, and has more of a deep thud sound great for Keherwa & Daadra Accompaniment.
