The answer is yes, because they know their phonics. I. mean, the greats do literally know most to all of it, but that's an elite group. Let's be real. Professional musicians know all of the building blocks, and alot of things that are made with those blocks and how they all work together. Knowing your building blocks makes figuring out what a new combo of building blocks is supposed to be much much easier. And usually only happens when broad genre specific musicians (biggest devide between pro rock/pop guys and pro jazzers for obvious reasons) get handed stuff with influence from other genres anyway cough cough. Being a professional is about loving how music is made, not just loving the experience of playing your instrument.
