Turkish March Composition
December 09, 2018 09:00PM
So I am composing a Turkish march. I am not new to music theory but I am sort of debating in my head as to what key the B section should be in. I figured I would have a C section in C major but different from the A section(like having lots of octaves in the right hand), and a D section in A minor, and possibly an E section in C minor but I am not sure at all what key to have the B section in.

As you can probably tell from this, I am writing in rondo form.

I know I want the last harmonic bit of the B section to be a pre-tonic chord that leads to C major.

That gives me these options:

    [*] C minor
    [*] G major
    [*] F major
    [*] D minor

C minor I can cross off the list because if I am going to use C minor, I might as well use it for a section rather than just to lead back to C major. D minor, I don't think I would want to use either. So this leaves me with either a plagal cadence(IV->I) or a perfect cadence(V->I). Since a perfect cadence implies finality, I think I should avoid that for in the middle of a rondo. But I would use it in the coda. So this leaves me with F major as the final harmonic bit in the B section. If I have the B section in one of these keys:

    [*] D minor
    [*] Bb major
    [*] G minor

this gives me something along the lines of V/V(of section) = I(of piece)

So maybe I should do something like this:

Dm, Am, Dm, Gm, Bb, Eb, Bb, F, C(start of A section)

But should I end the B section with a plagal cadence and should I modulate to Bb major to do this? On the one hand, this avoids too much finality. But on the other hand, it also seems unusual to have the B section in the key of the ii chord or a distantly related key.
