How long would it take a high-level (mathematical/musical) genius to say, for example, learn the violin?
(And on a similar note, a very high IQ should correspond to the ability/capability to learn mostly anything if the person puts their mind to it, no?)
Therefore, how long would it take such a high-level genius to play excellently on the violin or rapidly learn musical notation to be able to compose and read music fluently, for example?
Interested in hearing your thoughts.
