Hammond Organ


The Hammond electronic organ was developed with churches in mind, as a lower-cost alternative to pipe organs. But in Philadelphia, a keyboard player named Jimmy Smith was inspired by early jazz experiments on the instrument, and found a devastating way to adapt the new bebop style to the Hammond B-3.

It seeded a new tradition of organ players in Philadelphia — major figures like "Groove" Holmes, Jimmy McGriff, Papa John and Joey DeFrancesco, and Trudy Pitts — and started a new sound in jazz at large.
