I came on this radical thought a while ago ---

The western music scale is composed of two "parts"

Let's look at C Major

C E G B & D F A C

disagree? Well let's just see what I can do on the Accordion...

the first part goes well with the C Major chord, and the second part goes well with the G Dim 7th chord...

incidentally, you can also fit in the F Maj chord

F A C E


and if THAT doesn't confuse you ...

the Greeks had "tetra-chords" .... allegedly this is the basis on which our scales are built...
:-)

and, thank you, Boob Bolton, my name's Rob_i_n   ;-)

No.... I'll just let the typo stand.... :-)

So Bob, I'd like to "borrow" part of your pedantic description for my "Opus"...

Hope your silence on "The Opus" reflects tacit approval overall, rather than disinterest caused by me getting things totally screwed up...
