Jimmy Smith (December 8, 1928 February 8, 2005) was a jazz musician whose performances on the Hammond B-3 electric organ helped to popularize this instrument. In 2005, Smith was awarded the NEA Jazz Masters Award from the National Endowment for the Arts, the highest honors that the United States bestows upon jazz musicians.
While the electric organ was used in jazz by Fats Waller and Count Basie, Smith's virtuoso improvisation technique on the Hammond helped to popularize the electric organ as a jazz and blues instrument. For ballads, he played walking bass lines on the bass pedals. For uptempo tunes, he would play the bass line on the lower manual and use the pedals for emphasis on the attack of certain notes, which helped to emulate the attack and sound of a string bass.
