Hammond organ refers to music built around the distinctive electro‑mechanical Hammond tonewheel organ (especially the B‑3) and its swirling Leslie speaker. The style blends bluesy gospel harmonies, jazz improvisation, and R&B groove into greasy, percussive organ leads and walking or boogaloo bass lines (often played on the organ’s pedalboard or lower manual). In bands, the Hammond often fronts an "organ trio" with guitar and drums, but it is just as iconic in larger soul, funk, and rock ensembles. Its sound is characterized by drawbar sculpting, key click, percussion settings, palm smears, glissandi, and expressive chorale/tremolo Leslie switching that moves from warm pads to roaring, overdriven leads.
