I wanted to add that I have recently experienced this phenomenon where I wanted to reject a piece of music that I had already finished on paper while I was entering it into the computer. Because it was sounding so horrible and bad I thought that my composition was just a dud and that sometimes things just don't work out the way I intend them, musically speaking. I was ready to trash the composition but instead decided to just finish entering it into the computer to see what it would sound like in its entirety. It turned out much better than I thought and now I enjoy it immensely! I think I just had to get used to the weirdness of the piece. It was good that I didn't write the piece in the sequencer/notation program/DAW because the immediate feedback of the process of writing it would have severely discouraged me from continuing it. I am glad that I was able to delay judging it until it was finished and not being able to hear it helped me in this process. (In case someone is interested the piece I am talking about is my Arpeggio Etude for Piano). I thought I would share this anecdote in case it might help someone who is suffering from writer's block or finds themselves prematurely rejecting everything they come up with as I have sometimes done. Thanks for reading!
