Hi,
I have been playing piano since 1st grade, and am currently in 10th grade. I have earned the Certificate of Merit Level 10 this year, and have composed my own songs and won state level competitions, but that was when I was in 6-8th grade. I haven’t participated in any competitions. How much will this boost my college applications?
EDIT: Is it also possible for me to use my piano compositions in my college apps?
I would ask a music teacher or someone who plays piano really well to listen to your compositions. If they think they are good, you can submit your recordings as supplemental material. There are different ways that colleges will accept music submissions, so check on the website of each college you are considering.
Don’t include middle school awards in your college application. You can piano as an activity and include awards you received in HS. IMO any musical supplement you send would have to be amazing (both the composition itself and the playing) for it to help at all so get a professional opinion before sending any music supplement.
