Position leadership description

Personally I’d question if using it as an extracurricular is something you’d like to do but in the vent rant you do use it something like this would suffice.

I regularly play the violin as a hobby for x years and have achieved xyz accomplishments (such as winning a competition or something like that if none disregard).

I have also done x. (Something quantitative like play at a 12 hour recital or anything with a number).

Through playing the violin I have learned xyz charecter traits that helped me do xyz.

Hope this helps and feel free to comment if you’s like clarification as I’d be more than happy to help!

PS: Please note I have near zero clue about musical terms.
