For example, above we said that D – G# forms a tritone, and Bb – E as well. Music theory as a whole is a very large topic, and it can be used to create some really interesting sounds and colors in a piece of music.

It’s important to remember that part. Thus, the VI7 chord is “V7 of II”, II7 is “V7 of V”, etc. This is because Jazz is more fluid and relaxed in terms of function rules, and more about color and feeling than classical music. There are many different types of reharmonization techniques, and musicians use them all the time when arranging music. Consider a “ii-V-I” progression in the key of C major (Dmin7 – G7 – Cmaj7). Really, that’s where the color and tension are created, no matter what voicing you use as a piano player. The bII7 (Db7) chord also contains that same tritone, but written as F – Cb, and it also resolves to the C – E in the C Maj. Also notice that the iimin7 ⇨ bII7 ⇨ I progression includes a descending sequence of semitones, going from D ⇨ Db ⇨ C. This also creates an additional pull to the tonic chord.

Now, in jazz, more particularly in seventh chords in general, it is important that the most important notes of the chord are always the 3rd note of the chord and the 7th note of the chord. Using this substitution gives us this progression: Imaj7 (CMaj7) ⇨ IVmaj7 (Fmaj7) ⇨ iimin7 (Dmin7) ⇨ bII7 (Db7) ⇨ I (C Maj): The G7 chord contained the tritone B – F, which resolved to C – E in the C Maj chord.
