Hello everybody,
I was used to compose strictly using only diatonic harmony and scales. So when I composed a piece, I usually chose one key and took all the material, like the chords and the melody from the notes of this key. And I tried to compose pieces that I like with this diatonic material, for years, day after day, but I never came out with any stuff that I liked, although I used thousands of note combinations and chord combinations over the years (imagine, I try to compose a piece that I like, every day), there was not one thing that I liked. So I began to be in doubt about all the diatonic cage, I thought I had to experiment with other scales or harmonies. Obviously the sound of diatonic music, was not what I was searching for in my brain, which confused me a lot, because there were many diatonic pieces of rock-bands that I liked a lot. But I was composing for two acoustic guitars and everything I played, which was diatonic, sounded like folk music on the acoustic guitar. And I was looking for a more jazzy, complex, flamenco-style.
So I stated to experiment adding non-diatonic-scale tones. I build up progressions from a diatonic scale, but add some altered chord tones, that are not in the key of the piece. So I play one bar for example a "Bm" chord and then the next bar a "D+5" (which is dissonan t)and then again resolve the dissonance in the next bar with an "A" chord, than mybe a "Bmadd-11" etc. If I play the chords on their own it sounds very dissonant, but if I add a melody/theme to the progressions it seems to fit and the overall diatonic sound character is gone and it seems please me.
My question now is, is this still tonal music and is it possible to play such chord progressions, where one chord is dissonant and the next consonant again etc. ? Or is this already atonal music or "wrong" music?
