I found a “grand prize Virtuoso” international music competition online.
Is this a real one? Open internationally to various groups ranging from 6- 25 years of age. They seem to have the selected winners perform at different European locations.
probably is a real competition, probably no one has heard of it. Would you be able to travel to Europe to perform in the winners concert if you won? It doesnt seem like something that would supplement your college application but could be fun if you won.
Manhattan school of music precollege has a list of competitions for its students. I just checked, this one is not listed. Good luck, There are lots around that are less expensive and better know.
