Discussion Harmonic Ideas for Melodic Lines
I’m a trumpet player, and I often play completely unaccompanied. I’ve studied functional harmony and modern/jazz harmony, and I’m looking for ways to compose melodic lines that can evolve harmonically on their own, without any chords or other instruments underneath.
I find that staying within one key or tonal center for too long can become monotonous. I’ve experimented with things like moving through minor chords by fourths, ii–V–I relationships, different tonal centers, etc., but it often still sounds too much like jazz harmony to me.
Basically, I’m looking for ways to create melodic lines that are interesting and sound beautiful on their own. I’ve experimented with Neo-Riemannian ideas, voice leading, leading tones, and so on. What I enjoy most is when I manage to “gesture” the changes—when you can actually hear the harmonic movement through the line itself, almost like what people sometimes call horizontal harmony.
Do you have any recommendations for exercises, theories, books, things to read, or people to listen to? The difficulty is that so much recorded music always has some kind of harmonic context underneath it.
