Charlie Parker (1920–1955), nicknamed "Bird," was a pioneering American jazz saxophonist and composer who played a central role in developing bebop—a style marked by fast tempos, complex harmonies, and virtuosic improvisation. His groundbreaking compositions include "Ornithology," "Ko Ko," "Now’s the Time," "Donna Lee," and "Yardbird Suite," which have become enduring jazz standards. Despite his short life, Parker's profound influence reshaped modern jazz and continues to inspire musicians worldwide.
