Enjoy! Press the number keys or the number buttons to move positions. On the keyboard, press the up or down arrow to glissando. There are many, many, more notes you can play in these 7 positions, but these are just some commonly used notes. Also, the trombone noises are recorded from my trombone, because the scratch noises only go so far. Sorry if they aren't in tune. Haven't been able to tune my trombone since school stopped.
Forgot to put this above, but please don't listen to this at full volume. The trombone is not generally a quiet instrument.
