here is some info to know if ur starting music school ;0 -from a person that goes to music school for years!!
music school is basically second school unless you dont have it everyday and it has 3+ classes! its not scary n stuff and ppl r very nice and you can make much friends (belive me i have social anxiety and have no friends in school but have A LOT in music school)! also its very chill and of course you need to study music theory n practice piano but its very fun!! i love going in music school >;D
also if u have/had bad expirience with music school just know not every is the same tho and this is jus MY experience ;3
