Natural talent DOES exists, but limitations do not, no matter how tone deaf you are you can force yourself to play any instrument in the world trough hard work and practice, no matter how bad you are at math, whit lots of practice an time you can hack anithing, (i should know im both tone deaf and dislexic wich severely impairs math and playing musical instruments, i beat math, and now im better at it than most regular people, and i can play piano by memory and extreme amounts of practice, dislexia does get you wondrous memory and far better attention and focus than normal people so its a fair trade-off)
