My son has just uploaded two videos to his YouTube channel - performing his arrangements of ‘Hallelujah’ & ‘Drivers License’. There’s also an original piece which he composed as a 13 y.o. I think they’re pretty good for a self taught musician (edited: I’ve since checked out a lot of other popular arrangements & IMO his are pretty awesome for a self taught musician) and illustrates how digital technology is a game changer & kids can learn so much on their own by exploring the internet.

Edited: Music is one of the co-curricular activities he will be listing for his Uni application. He plans to study R & D engineering. His other co-curriculars are Olympiad Maths & athletics (unfortunately, very little happening due to COVID lockdown, so he’s lately been directing his efforts toward music).
