I am currently working on the introduction to the third movement of my quintet. I struggled for some time with finding the mood and harmonic language to fit into the work but finally found something that works.
I began by recording myself improvising on the double bass and then overdubbing my reaction to the recording. I am now transcribing the recording and arranging it for the appropriate instruments (with a few alterations).
The introduction makes me think of hiking in the woods or being the first to wake up at a camp outing and watching the sun rise and shine its light through the dew on the grass.
