Your neighbors survived the screechy violin months. That noise is what paid for the song.

Every skill has a stretch that sounds bad, and there is no route around it. The screechy months are not wasted time before the real playing; they are the real playing in its early form, and the eventual song is made out of them. Nobody reaches the good noise without producing the rough one first. Being heard while you are rough is part of the price.

Let yourself be audible this week instead of only practising when the house is empty. Thank whoever has put up with it so far. Then keep making the noise that pays for the song.
