By “cannot … any” do you mean “there are no instruments you can” or “there are instruments you cannot”? The former seems completely wrong to me, you definitely can become an expert in playing the kazoo or the triangle in 6 months. (Even if you mean the latter, I think there are very few instruments you can’t become an expert in in 6 months, if you have no other job and no children and can spend 80 hours a week on it.)
I mean for most instruments you cannot, with exceptions like the triangle. About kazoo—isn’t basically vocals with an extra sound effect? So its difficulty would be bounder from below by the difficulty of learning to sing.
