Pretty happy with Section A (The beginning). I just played around with some octave displacement (moving the pitch of the notes up 8 notes) for a few notes in the piano part. See example below. Now that I have the notes down for Section A I have a lot of details that I need to add like bowing markings for the strings and dynamics. These details require a lot less concentration but are also a lot less fun to write. I will also have to hone in on any notation that could be written more clearly or accurately to maximise readability for performers. Clear and accurate notation saves a lot of time when the performers come to rehearsing your music.
Also continued working on the piano part for the first half of the middle section (main theme/Section B) as shown below. The piano part in bar 56 (same notes 2 octaves apart) reminds me of the second movement of one of my favourite piano concertos by Shostakovich: piano concert no. 2
