Music is made of words - scale-specific gestures, of which there are hundreds, perhaps thousands, typically arranged in some kind of harmonic context so you can make reasonable guesses about what's coming next

Some genres of music are that way. Other genres have different conventions, ethics, and aesthetics. Even within harmonically oriented Euro-traditions, great weight is given to a musician’s ability to play what does not easily “fall under the fingers.”

There’s nothing wrong with Smoke on the Water but it is totally played.
