This is the backing track for the potpourri of popular themes from mainstream music, transcribed, transposed and arranged for a small group of wind or brass instruments.
Avicii - Hey Brother
Pharrell Williams - Happy
Avicii - Wake Me Up
This is the backing track only, no lead instruments. Use it to practice or play in front of an audience.
This is targeted at beginners with a modest ambitus and resistance.
I work on that with pupils of 10-14 years old who play trumpet for one or two years.
