Lesson 159: Sequence
What Is Sequence?
A sequence is the restatement of
In this lesson we are going to look at how sequence can be used in harmony and/ or rhythm. The use of melodic sequence is talked about in my lessons on motif and motivic saturation.
Example 1: Beatrice by Sam Rivers
In Sam Rivers' beautiful composition Beatrice, sequence is utilized extensively:
The sequences in the harmony are:
Fmaj7 - Gbmaj7 - Fmaj7 - Ebmaj
The roots of the chords form a sequence: first a scale tone, then a half step up, then back to the original tone and then down. The sequence is not literal, the ending is always different and that makes it more interesting.
Example 2: Giant Steps by John Coltrane
The changes of Giant Steps are the following:
|Bmaj7 D7 |Gmaj7 Bb7 |Ebmaj7 |Am7 D7 | |Gmaj7 Bb7 |Ebmaj7F#7 |Bmaj7 |Fm7 Bb7 | |Ebmaj7 |Am7 D7 |Gmaj7 |C#m7 F#7 | |Bmaj7 |Fm7 Bb7 |Ebmaj7 |C#m7 F#7 |The second four bars are a sequence of the first, starting on G instead of B. In the second half of the tune, the chords go through the same two bar progression, starting in Eb and then sequenced to the keys G and B and finally back to Eb.
Example 3: Pachelbel's Canon Progression
In Pachelbel's Canon the chord progression is:
D - A
So, the roots of the chords go a fourth down, then up a scale step and again a fourth down and so on...
Example 4: II - V - I or II - V Sequences
The chord progressions of lot of jazz standards have an abundance of II - V - I's or II - V's that change the key center temporarily.
