Charlie Parker revolutionized jazz in the 1940s by developing bebop alongside Dizzy Gillespie and other innovators. His virtuosic alto saxophone work, harmonic sophistication, and rhythmic inventiveness set the standard for modern jazz improvisation and influenced every jazz musician who followed.
Thelonious Monk composed "Round Midnight" as one of jazz's most haunting and harmonically complex standards. Monk's distinctive compositional voice appears throughout his catalog: angular melodies, unconventional chord progressions, and a compositional approach that demands both precision and interpretive depth from performers.
