its kinda rare for me to wake up and immediately try to respond to a comment first thing in the morning, but here we are i disagree. i'd argue the empty spaces are there to let the music breathe, and i have considered of keeping the "movement" going in one way or the other, either by the piano playing scales, rapid lines, the syncopated triplets, arpeggiando on the strings, timpani rhythms, etc. also, i dont think every empty space has to be filled with motivic movement. does every piece has to have a melody "naked"? and i pretty sure have varied the harmony and texture. the first introduction to the full theme its literally just pizz. string and high register piano playing 6th broken up (which adds movement, by the way), the repeat of which (b.194) just removes the piano entirely, the first entrance of the second theme is played by cello only, with piano and pizz violin to accentuate the syncopated rhythm, the measures before that is another thinning of textures after a loud section, etc etc. i mean, i like it, so...oh well lol yeah, the themes are long and therefore had to be repeated. however, if i cut those repetitions the themes wouldnt be prominent. hell i did in fact cut the first theme in the repetition. most of the systems include 2-4 bars, with the exception of a few bars where there are few notes to play. i do not think crowding is an issue here. response: added references: and probably more. i couldnt find anything outside facebook discussions to be honest. HOWEVER, most of the chamber pieces including a piano that i've score read have the non-piano instruments be in smaller staves. response: also note, i'd rather have a seemingly impossible part and have to revise them after some feedbacks than not using the instruments to its fullest potential. part of why i fell in love with classical music is that you can get SO MUCH out of one singular instrument. the fact that composers have exploited many ways out of an instrument to serve their vision is so fascinating to me. maybe its innocent for me to think that way. of course, you have to consider the performer and the rehearsal, but, im gonna be real, i dont think this piece is ever gonna be performed. AND, if it was, or if i were to compose a piece that WILL be performed, then yes, i'll absolutely not go overboard and stuff, strip down the techniques, and be more lenient with them. this DOES NOT mean i do not think of idiomatic writing (refer to the my quoted response). also 6 bars of left hand open strings pizzicato played near the edge of the fingerboard is impossible? but, as all art are, it comes down to taste. so, fair enough thanks for the comments!!!
