Most Indian jazz fusion pairs the tabla with a guitar, a saxophone or a piano. Melodic Intersect also uses the Hammond organ, the electric organ that powered soul jazz. Here’s why the combination works: what the Hammond does that a piano can’t, how it relates to the harmonium that Indian musicians already know, and how Greg Hatza came to play it beside tabla and sitar.
What is a Hammond organ?
The Hammond is an electric organ first made in 1935 by Laurens Hammond and John M. Hanert. Instead of pipes it uses spinning metal tonewheels, each turning in front of an electromagnetic pickup, and a set of sliding drawbars that mix different harmonics into the sound.
The drawbars are an early form of additive synthesis: the player builds a tone by choosing how much of each overtone to add. The best-known model, the B-3, was made from 1954 to 1974 and added a “harmonic percussion” feature that gives each note a sharp, bell-like start.
What makes the Hammond sound so distinctive?
Two things: sustain and movement. A Hammond note keeps sounding at full strength for as long as the key is held, unlike a piano note, which fades. The movement comes from the Leslie speaker, a separate cabinet with a rotating horn and drum.
The Leslie’s rotation adds tremolo and a slight Doppler shift in pitch. It has a slow “chorale” speed and a fast “tremolo” speed, and switching between them is one of the organ’s most expressive gestures. Don Leslie began making the cabinets himself in 1941, after the Hammond company declined to sell them, and jazz organists quickly adopted them.
How did the Hammond become a jazz instrument?
Through Jimmy Smith. From the 1950s his B-3 playing inspired generations of players and set the standard line-up for soul jazz: the organ trio, in which the organist plays the bass line and no bass player is needed.
That detail matters for fusion. An organist who can cover the bass leaves room in the band, and a tabla player can fill it. The bayan, the tabla’s larger drum, bends its pitch under the heel of the hand, so it can answer a bass line as well as keep time. Our guide to the tabla in jazz explains the drums in detail.
Is there an Indian cousin of the organ?
Yes: the harmonium, a hand-pumped reed organ. It reached India in the mid-19th century, and Indian makers reworked it to be played sitting on the floor. It became central to qawwali, ghazal, kirtan and bhajan, and is widely used to accompany classical singers.
It was also controversial. All India Radio banned it from 1940 to 1971 because a keyboard of fixed pitches cannot produce the slides and ornaments (meend and gamaka) that Indian classical music relies on. Any keyboard player in Indian fusion faces the same limit, and it shapes the role the organ plays.
Why does the organ work with tabla and sitar?
Because its sustain can do what the tanpura drone does. In Indian classical music the drone holds the tonic and fifth throughout, and every note of the raga is heard against it. A Hammond can hold those notes indefinitely, with the drawbars shaping the overtones, while the sitar plays the raga on top.
The organ can then move from drone to groove. It can hold still under an alap, switch to a bass line and chords when the tabla starts its cycle, and play the melody itself where it has the lead. For how the two musical systems line up, see Raga vs. Jazz Modes.
How did Greg Hatza come to play Indian fusion?
Hatza grew up in Reading, Pennsylvania. He started piano at five and switched to organ at fifteen, and he was playing professionally at sixteen. In the late 1960s he recorded two albums for Coral Records with guitarist Eric Gale and drummer Grady Tate.
When the organ fell out of fashion in the 1970s he moved to electric keyboards, then returned to it in the 1990s, inspired by Joey DeFrancesco, and formed the Greg Hatza ORGANization. He holds a composition degree from the Peabody Conservatory and a master’s from Towson State University, where he later taught. He also spent more than two decades studying Indian classical music, including sitar and tabla. His artist page has the full biography.
Where can I hear Hammond and tabla together?
On Melodic Intersect’s 2026 album Woven Paths. In “Between Two Worlds” the sitar drops out entirely, leaving a warm, blues-tinged Hammond, piano and tabla in conversation. “The Turning Point” pairs a heavy funk groove on tabla with jazz and blues organ, and the title track closes the album on bass and tabla under organ.
The same album also uses a ROLI keyboard for atmospheric, pitch-bending textures, and piano throughout. For Hatza on piano with tabla alone, listen to the duo album Talking Hands. JazzWeekly wrote that he “plays a variety of keyboards to team with the hands of tabla man Enayet Hossain.”
What should a keyboard player listening for this notice?
Listen for three things. First, when the organ holds a drone and when it moves, and how that tracks the tabla entering. Second, whether the left hand or the tabla’s bayan is carrying the bass. Third, how the organ avoids notes the raga leaves out, even when the underlying scale would allow them.
