 Entwistle identified his influences as a combination of his school training on French horn, trumpet, and piano (giving his fingers strength and dexterity).Musicians who influenced him included rock and roll guitarists Duane Eddy and Gene Vincent, and American soul and R&B bass guitarists such as James Jamerson.In turn, Entwistle has been a considerable influence on the playing styles and sounds used by generations of bass guitarists that have followed him, including Tom Hamilton, Geezer Butler, Steve Harris, Matt Freeman, Krist Novoselic, Cliff Burton, Ian Hill, Geddy Lee, Billy Sheehan, Victor Wooten, Tom Petersson, Sam Rivers, John Myung, and Chris Squire.
