Every instrument requires a certain amount of time, dedication and skill to learn how to play, but some more than others. There are those that just seem impossible. Which instruments are the hardest in the world to learn how to play?
I think the saxophone is one of the hardest instruments to play. Not only because of all the different air holes you need to learn how to cover, but also the amount of breath and breathing control required.
I'm guessing, but I would think that any string instrument that is played with a bow would be listed as the hardest instruments to learn. The strings are pulled so tight, and far away from the fret board, both hands need to be doing two separate actions at two different speeds, it just seem like it would be really hard to me.
