Great players (musicians) are known for how well they play, their style of play, and if they hit mostly correct notes.
Great artists are known for the songs they release and how well those songs connect with a market.
In general if you practice really hard you can be known as a great player. You can read charts and play fast and take solos and play to a click. And add a little finesse.
But the only sure outcome of relentlessly practicing being an artist is that you are in fact an artist. You might have made five albums but they’re not very good and no one listens to them…you’re still in artist but all that time and practice and commitment didn’t make you a great one. Because artists trade on musical emotional connection. Not ability or worth ethic or commitment. Ultimately no one cares if a rock band is good at guitar…people only care if they have an awesome rock song.
»» Of course there’s considerable overlap here. Most players are artistic. And most great artists got to be great because of some degree of skilled musicianship.
