Musical maturity will occur on a faster track if the performance comes
from a trained ear. Not memorized but as the actual tool to lay down what
occurs musically in your mind. The fraternity of Jazz or modal players who are well
along in this process may not have arrived at this confidence from
the tablature method. But, they will tell you (however awkwardly and
possibly with a shrug) that they do not know how they play. "It just
happens." Well, you can be sure their proficiency comes from a clear
mind and an ear that's directly riveted to their chops and the incidence
of luck. This process may happen by chance but the odds against it are
remote - very remote!
