Hi Roady
I call it a melodic layout, because there is no really reasonable chord playing with augmented (only major thirds or augmented triads)
But how versatile is the solo tuning with respect to chord play? I don't play the solo tuning so I took a look at how well it does in a few different keys with respect to chord play. Here is the 12-hole solo tuning layout
1 2 3 4 5 6 7 8 9 10 11 12
----------------------------------------------------------------------
blow: | C | E | G | C | C | E | G | C | C | E | G | C | key out
draw: | D | F | A | B | D | F | A | B | D | F | A | B |
----------------------------------------------------------------------
1 2 3 4 5 6 7 8 9 10 11 12
-----------------------------------------------------------------------
blow: | C# | F | G# | C#| C# | F | G#| C#| C#| F | G# | C#| key in
draw: | D# | F#| A# | C | D# | F#| A#| C | D#| F#| A# | C |
-----------------------------------------------------------------------
And here are lists of the diatonic chords or chord pieces (one note doesn't count) available in a few keys.
Key of C:
I chord (C maj): root, 3rd, 5th
II chord (D min): root, 3rd, 5th
III chord (E min): root, 3rd
IV chord (F maj): root, 3rd
V chord (G maj): 3rd, 5th
VI chord (A min): 3rd, 5th
VII chord (B dim): root, 3rd, 5th
Key of Bb.
I chord (Bb maj): 3rd, 5th
II chord (C min): root, 3rd, or root, 5th (tongue block)
III chord (D min): root, 3rd, 5th
IV chord (D# maj): root, 5th (tongue block)
V chord (F maj): root, 3rd
VI chord (G min): NO CHORD
VII chord (A dim): 3rd, 5th
Key of G:
I chord (G maj): 3rd, 5th
II chord (A min): 3rd, 5th
III chord (B min): root, 3rd
IV chord (C maj): root, 3rd, 5th
V chord (D maj): root, 5th (tongue block)
VI chord (E min): root, 3rd
VII chord (F# dim): root, 5th (tongue block)
Key of D:
I chord (D maj): root, 5th (tongue block)
II chord (E min): root, 3rd
III chord (F# min): NO CHORD
IV chord (G maj): 3rd, 5th
V chord (A maj): NO CHORD
VI chord (B min): root, 3rd
VII chord (C# dim): 3rd, 5th
Did I make any mistakes or leave any chords out? Like I said, I don't play the solo tuning.
The first thing that I notice is that the availability of chord pieces is key dependent. The second thing that I notice is that there are no chord pieces available for some chords. Maybe somebody that actually plays solo tuning would tell me what the worst chord playing key is for the solo tuning. The third thing that I notice is that some chord pieces are only achieved by tongue blocking.
With the augmented tuning and for any key one can play the following chord pieces:
I chord: root, 3rd
II chord: 3rd, fifth
III chord: 3rd, fifth
IV chord: root, 3rd
V chord: root, 3rd
VI chord: 3rd, 5th
VII chord: NO CHORD
Looks pretty darn good to me! Looks ... versatile ... dependable ... simple.
