I have a question about sonata from and need a bit of help on the matter. I am composing my second string quartet and I want to follow a more traditional four-movement set up this time. I want the first movement to be in sonata form, but I am not going to use traditional tonality to make it happen. This is where I need some suggestions on how to do this since sonata form originally used tonality to signal each section's entry and departure.
Also, maybe a list of 20th/21st century pieces to listen to that employ a more modern method of sonata form. I know that Bartok used sonata form in his string quartets (x,y,z, cells, etc.), but I'm not sure about the other composers. Thank you all!
