Alessandro Alessandroni (March 18, 1925, Rome) is an Italian musician.
He plays multiple instruments, including the guitar, mandolin, mandolincello, sitar, accordion, and piano, and has composed over 40 film scores and countless library music. Being an accomplished whistler, Alessandroni collaborated with his childhood friend Ennio Morricone on a number of soundtracks for Spaghetti westerns. Morricone's orchestration often calls for an unusual combination of instruments and voices. Alessandroni's twangy guitar riff is central to the main theme for The Good, the Bad and the Ugly.
