I'm in the process of writing a piece in sonata form, but I feel that I don't really know how to plan the music so that it is coherent. Could someone go through their process when it comes to planning.
I mainly want to know how detailed you make plans, and if you come up with themes before or after, and what I should be doing regarding tonality structures.
And also, do you have any tips for making interesting accompaniments for orchestral pieces? I want to move away from block chords and into something more like the orchestration of Dvorak's 9th. I use that as an example because it's something I've been listening to a lot recently.
Thank you for your help!
