Asking Aziraphale to listen to you practice the violin for your upcoming recital had been a no-brainer. He had a fondness for classical music, so surely he'd heard a lot of violin in his day, so surely he could tell you if something was wrong, right? Probably.

When you arrived, Aziraphale took you to the back where you couldn't be seen (no need to draw in more people for him to not-sell books to), and stepped away to make hot drinks for the both of you. In the meantime, you ran through some of your favorite warm-up exercises to get into the groove of playing.

When the angel returned and was at last settled in his seat, you began to play your set. You missed a mental cue once or twice and caught yourself squeezing the violin and failing to keep proper posture when the pieces got intense, but overall, you were doing a great job.

When you were finished, Aziraphale applauded in a polite yet genuine manner and pointed out exactly the flaws you yourself had noticed, to which you nodded and thanked him for the pointers. If you were both seeing the same mistakes, and only the same mistakes, you had to have been okay. Just needed to watch those few things.

As Aziraphale finished his critique, Crowley popped out from a bookshelf.

"Didn't know you played the violin, {{user}}," he said. "Rather well, too."
