In jazz, the Tadd Dameron turnaround, named for jazz composer Tadd Dameron, "is a very common turnaround in the jazz idiom",Coker, et al (1982). Patterns for Jazz: A Theory Text for Jazz Composition and Improvisation, p.118. . derived from a typical I−vi−ii−V turnaround through the application of tritone substitution of all but the first chord.

The Tadd Dameron turnaround may feature major seventh chords, and derive from the following series of substitutions, each altering the chord quality.Bahha and Rollins (2005). Jazzology, p.103. .Richard Lawn, Jeffrey L. Hellmer (1996). Jazz: Theory and Practice, p.118-19. . {| |width="45px"| C∆7 ||width="45px"| Am7 ||width="45px"| Dm7 ||width="45px"| G7 | | || | (original) |- | | C∆7 || A7 || | D7 || G7 | | || | (dominant for minor triad) |- | | C∆7 || E7 || | A7 || D7 | | || | (Dameron turnaround: tritone substitution) |- | | C∆7 || E∆7 || | A∆7 || D∆7 | | || | (major for dominant seventh) |} The last step, changing to the major seventh chord, is optional.
History Dameron was the first composer to use the turnaround in his standard "Lady Bird", which contains a modulation down a major third (from C to A). This key relation is also implied by the first and third chord of the turnaround, C∆7 and A∆7.Lyon, Jason (2007). "Coltrane's Substitution Tunes", in www.opus28.co.uk/jazzarticles.html. It has been suggested that this motion down by major thirds would eventually lead to John Coltrane's Coltrane changes. The Dameron turnaround has alternately been called the "Coltrane turnaround".Scott, Richard J. (2003). Chord Progressions For Songwriters, p.234. .
Further examples of pieces including this turnaround are Miles Davis's "Half Nelson" and John Carisi's "Israel".
