Lesson Seven • Diminished Scale Tetrachords
When last we encountered the Diminished Scale, we isolated four 7th-chord arpeggios that are contained in it. This time out we’ll look at the minor tetrachords (four-note scale fragments) that are also found in the Diminished Scale (the red notes).
These tetrachords can be used to create melodic patterns as shown below:
They also combine with the dominant arpeggios featured in the last lesson to create even more harmonic implications. But that’s the subject of the next lesson.
This concept is explored in greater detail in my book Jazz Guitar Structures, available from Mel Bay.
