This page shows how the tonal clusters are formed, using the notes in Row 1.
The Row consists of the notes Bb, Db, Eb, G, Ab, Bb, Db, Eb, G, Ab, Bb.
Select every other note to form the first cluster.
Bb - Eb - Ab - Db - G.
Getting mixed up? Ok then lets mark each tone by its position in the Row. The slash will mean "or"
Bb = 1, Db = 2, Eb = 3, G = 4, Ab = 5, Bb = 1/6 (1 or 6), Db = 2/7, Eb = 3/8, G = 4/9, Ab = 5/10, Bb = 1/6/11
Remember the numerals indicate position within the ROW and are not fractions or chord functions. The numbers are necessary to keep from getting mixed up as the complexity increases.
Row One was Bb, Db, Eb, G, Ab, Bb, Db, Eb, G, Ab, Bb. Now we will start building the tonal clusters.
1 is the position of Bb and 3 is the position of Eb. We use Bb(1) on the bottom and Eb(3) on the top. Every other note is how the clusters are formed.
Now use Db(2) and the bottom and G(4) on top.
Eb(3) on the bottom and Ab(5) on top.
G(4) on the bottom and Bb(1/6) on top.
Ab(5) on the bottom and Db(2/7) on top.
