Treatments of the ii-V7-I Chord Progression in Jazz Improvisation w/ Dr. David Detweiler

Join Dr. David Detweiler, Assistant Professor of Jazz Saxophone at Florida State University as he explores treatments of the ii-V7-I chord in jazz improvisation. The art of jazz improvisation demands that jazz performers create musical ideas in real time based on the harmonic and melodic structure of a song. Jazz musicians are fortunate to have access to recordings made by noteworthy artists of the past and therefore can listen to and study the recordings of the jazz masters. The study and transcription of the jazz masters is crucial in understanding the art of improvisation. This presentation will show how master jazz performers Hank Mobley, John Coltrane, Sonny Rollins and Dexter Gordon use the ii-V7-I chord progression in improvisational practice. This chord progression is essential to jazz improvisation and has been handled by jazz musicians in many different ways. The proposed compilation of ii-V7-I improvisatory phrases will include a brief analysis of each idea. These analyses will display the artists’ similarities and differences in personal style.


Plus a Q & A with the live audience.
