What'd I Say in the context of The 500 Greatest Songs of All Time

An electric piano is a musical instrument that has a piano-style musical keyboard, where sound is produced by means of mechanical hammers striking metal strings or reeds or wire tines, which leads to vibrations which are then converted into electrical signals by pickups (either magnetic, electrostatic, or piezoelectric). The pickups are connected to an instrument amplifier and loudspeaker to reinforce the sound sufficiently for the performer and audience to hear. Unlike a synthesizer, the electric piano is not an electronic instrument. Instead, it is an electro-mechanical instrument. Some early electric pianos used lengths of wire to produce the tone, like a traditional piano. Smaller electric pianos used short slivers of steel to produce the tone (a lamellophone with a keyboard & pickups). The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar's Vivi-Tone Clavier. A few other noteworthy producers of electric pianos include Baldwin Piano and Organ Company, and the Wurlitzer Company.

Early electric piano recordings include Duke Ellington's in 1955 and Sun Ra's India as well as other tracks from the 1956 sessions included on his second album Super Sonic Jazz (a.k.a. Super Sonic Sounds). The popularity of the electric piano began to grow in the late 1950s after Ray Charles's 1959 hit record "What'd I Say", reaching its height during the 1970s, after which they were progressively displaced by more lightweight electronic pianos capable of piano-like sounds without the disadvantages of electric pianos' heavy weight and moving mechanical parts. Another factor driving their development and acceptance was the progressive electrification of popular music and the need for a portable keyboard instrument capable of high-volume amplification. Musicians adopted a number of types of domestic electric pianos for rock and pop use. This encouraged their manufacturers to modify them for stage use and then develop models primarily intended for stage use.

Jerry Lee Lewis (September 29, 1935 – October 28, 2022) was an American pianist, singer, and songwriter. Nicknamed "The Killer", he was described as "rock 'n' roll's first great wild man". A pioneer of rock and roll and rockabilly music, Lewis made his first recordings in 1952 at Cosimo Matassa's J&M Studio in New Orleans, Louisiana, and early recordings in 1956 at Sun Records in Memphis, Tennessee. He later became known for his chart topping country music recordings from the 1960s and 1970s. "Crazy Arms" sold 300,000 copies in the Southern United States, but his 1957 hit "Whole Lotta Shakin' Goin' On" shot Lewis to worldwide fame. He followed this with the major hits "Great Balls of Fire", "Breathless", and "High School Confidential".

His rock and roll career faltered in the wake of his marriage to Myra Gale Brown, his 13-year-old cousin. His popularity quickly eroded following the scandal, and with few exceptions, such as a cover of Ray Charles's "What'd I Say", he did not have much chart success in the early 1960s. His live performances at this time were increasingly wild and energetic. His 1964 live album Live at the Star Club, Hamburg is regarded by many music journalists and fans as one of the wildest and greatest live rock albums ever. In 1968, Lewis made a transition into country music, and had hits with songs such as "Another Place, Another Time". This reignited his career, and throughout the late 1960s and 1970s, he regularly topped the country-western charts; throughout his seven-decade career, Lewis had 30 songs reach the top 10 on the Billboard Country and Western Chart. His number-one country hits included "To Make Love Sweeter for You", "There Must Be More to Love Than This", "Would You Take Another Chance on Me", and "Me and Bobby McGee".
