Re: Hardest instruments to play
I've heard that harp is a hard one - lots of notes and when dealing with intervals greater than a step your reference point is thin air when you want to find that string, just as it is for tone deaf people trying to sing.
MFB, clarinet is not as hard as oboe - one reed vs two.
I've heard it said that violin, trumpet and drums are the worst instruments to buy your child ... screeeech! squeak! sqwark! bang! crash!
