I agree with this...but, there is something that needs to be addressed. The French call it 'Je ne sais quoi'. It is something that lifts the music to another level. Sure it is played perfectly, but there is something about it that just gives the energy...the 'just right' thing that makes it work. This is why I believe in developing one's own thing. Hopefully that thing resonates with what is trying to be achieved. Sometimes (most times?) it does not...in fact that's why loads of pro guys (front men, band leaders) go through lots of players. It's not that they aren't good...it's just that they aren't 'just right' for what is being sought. It's a fickle old world out there friends. And the more you delve the more discerning it gets.The ability to know what needs to be done and the generosity to give the other musicians, and the song, what they/it needs. Being authentic to whatever style you're playing, and flawless execution is expected.
