Substitute Dominant Chords
How many times have you played the same chord changes, chorus after chorus of "Autumn Leaves" or "Blue Bossa" or "All the Things You Are" or any tune? Wouldn't it be nice to throw in a few new chords here and there so that each chorus would be a little different? Jazz musicians do this all the time and the number one reharmonization device that they employ for this purpose is the technique of tritone substitution or subVs ("sub fives") for short. The use of substitute dominant chords to reharmonize tunes is a tried and true technique to freshen and revitalize chord progressions on the spot. Watch this lesson to learn what substitute dominants are, how they compare to primary dominants and how and when to use this essential device in tunes.
Practice Session 1 - Reharmonize Primary Dominants in ii-V-I Progressions
Practice Session 2 - Reharmonize Primary Dominants in Tunes
Listen to Hank Mobley play a B7 SubV over the F7 in the last measure of the bridge of his 3rd solo chorus (2:14) of his tune "Tenor Conclave" from his 1956 album of the same name.
