How do you develop a melody without making it feel like a mashup?
I’m writing an orchestral piece and I always start from the melody, because melody is the most characteristic part of my music.
The current piece starts on the subdominant (iv), and the progression is:
Dm - E - Am - Am - Dm - G - C - A7 - Dm - G - C - C7 - Dm - E - Am
(one chord per bar)
The problem is that the melody already feels completely finished with this progression, so I’m struggling to develop it further.
Whenever I introduce a new melody, it starts to feel more like a mashup than a natural continuation, which sounds awkward to me.
How do you usually develop a melody in this kind of situation?
