f major sonata first movement

Any feedback to improve on?

Could you attach a recording or playback from your editor? Thank you

Hello @Sonata_5 and welcome to the forum!

I perused your score and it seems, on the surface, like a solid sonata form movement!  There's a main theme which modulates from the tonic key of F major to C major.  Then, for the second theme, you take the listener to A minor with a codetta that brings the piece back to C major in preparation for the repeat.  There's a development which starts in C minor, uses liberal sequencing and modulation ending in C major in preparation for a return back to the main theme in F major.  The second theme is in F major this time and modulates to D minor instead of A minor.  Then, there's a codetta in C major bringing the piece to a conclusion in F major.  I would really love to hear how this sounds!  Like @Jqh73o mentioned, you could play it yourself or generate a rendition from your program, just to give us a general idea (although it's also fun to imagine).

By the way, I think I noticed a mistake in your score - in measures 6 beat 3 you have this:

I think the left hand should have a B natural as well since the right hand has one for a nice V/V G7 chord.

Thanks for sharing!
