Parker acquired the nickname "Yardbird" early in his career
and the shortened form, "Bird", which continued to be used for the rest
of his life, inspired the titles of a number of Parker compositions,
such as "Yardbird Suite", "Ornithology", "Bird Gets the Worm", and "Bird of Paradise."
Parker was a highly influential jazz soloist and a leading figure in the development of bebop,
a form of jazz characterized by fast tempos, virtuosic technique, and
improvisation. Parker introduced revolutionary harmonic ideas, including
rapid passing chords, new variants of altered chords, and chord
substitutions. His tone ranged from clean and penetrating to sweet and
somber. Many Parker recordings demonstrate virtuosic technique and
complex melodic lines, sometimes combining jazz with other musical
genres, including blues, Latin, and classical.
