Why would pattern recognition or playing music be unsolvable in a TM?
If you are talking about abstract problems (those which fall more under
the purview of philosophy) rather than problems that can be represented as
a program, you are committing a fallacy of equivocation (namely, you are
using two different meanings of the word "problem").
My original question was: Are there *provably solvable* (in the mathematical
sense) problems that cannot be solved with a TM. (If you can prove them to
be solvable, then it kind of implies that you can present algorithms to
solve them.)

Is it a provably solvable problem? If yes, then why cannot it be solved
with a TM?
