Bitonalism or Bitonality is a polemic term.It means the use of two different keys at the same time. Looks simple.But some theorists like by example, Paul Hindemith and Milton Babbit, the last one was the creator of the post-tonal nomenclature (Integer notation or pitch class set) posted that Bitonalism doesn't exist.He said that is impossible listen two tonalities at the same time.

Beyond Babbit ad Hindemith, many others use to think that Bitonality and Polytonality exists.I'm agree 100% .These ideas exist, and beyond modern classical music, you can listen it in Lithuanian folk, and in some tribes of India.Masters classical composers as Stranisky, Bartok, Aaron Copland , Charles Ives and others used Bitonalism a lot.Someone called Stravisnky the “father of Polytonality”.In Jazz music you can listen Bitonal stuff on the playing of Ornette Coleman (Double Quartet), Jazz group Bad Plus and piano player Richie Beirach.Some Allan Holdsworth 's songs also have some Polytonality.
But let's talk about guitar.I have been thinking for a long time if is possible play Bitonal music on guitar(I mean Solo Guitar).And I arrived to the next concept:It's not possible in an instant, in a freezing musical moment, that I called it “Vertical musical moment”, but it's possible in an “horizontal musical moment”, it means wth the passing of time.In a full Bitonal guitar composition or improvisation you will listen two keys or more for sure.
So this video lesson shows my ideas on this complex stuff. Now, I have more ideas that I will show in the next video lesson. The sound of Bitonalism is contemporary, dissonant, and we have a big new world for discover.I'm amazed with this stuff on guitar.
Hope you can find it interesting and useful.
