I seem to have the absolute worst time writing transitions. Any musical project that I start that has even a semblance of requiring a transition ends up taking months, trying dozens of combinations of fragments to glue 2 ideas together. Usually what ends up happening is the piece is abandoned.
I try many different types of transitions - silence, introducing material slowly, modulation, voice leading, crescendos, 1 bar fills, 2 bar fills, 4 bar fills, exposition, transient material. But it all just sounds like crap, it sticks out in my ears like a sore thumb, and ruins the musical flow.
I've tried distancing myself, coming back weeks, or months later with fresh eyes and ears, but 20 minutes later and I'm back exactly where I started.
I feel like I've exhausted all my possibilities and I'm not getting any better. Even when analyzing other composers transitions in score, I can clearly see some of the inner workings of how they did this, but when I try to take these ideas for myself, the execution is poor, and the music is at a standstill because of a really jarring piece of material.
Is there anything else I can explore (reading, examples, etc) that will help me improve? I feel as though I have no intuition in this black art, and this is the biggest thing holding me back from completing any music.
