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.
