I’m a brass player, started when I was about 7 and been at it every since. Done some good stuff with it, plenty of brass band national championships including one win, been on radio 2, played various concert halls but the best must be The Royal Albert Hall during proms season; that place is pretty special. Playing euphonium now after starting on cornet.
I’m also passable on the guitar and am teaching myself piano at the moment. As mentioned above, having a regular routine is key to getting better, even if it’s just 20 minutes two or three times a week.
