Frank Barrett called it elegantly as ‘an aesthetic of forgiveness’, where wrong notes are encouraged to be forgiven if the musician’s sincere efforts are behind it.
Later then “…one of the principles that jazz musicians live by is what I call mastering the art of unlearning because the enemy to jazz improvisation is your own routines and habits and success traps. There’s a temptation to play what you’ve done well in the past because you’re on the spot having to make something up in front of an audience.
So jazz musicians have to sort of trick themselves into unlearning their own routines and habits so they don’t automatically fall back into cliches.
Processes, in a way, are route maps of practices. Practices follow from principles. And never should it be the other way around. Jim Highsmith says it best :
“..what happens in too many organizations is that practices become static and then quietly elevated to the level of principle—something that can’t be violated…What happens is that slowly and surely, good practices become bad principles, or pseudo-principles”. So, for heaven’s sake, don’t get into this process trap.
