Many of the best instrumentalists (and singers for that matter) wether they are "classical" players or jazz players study(ied) with the same teachers for developing a solid foundation of technical mastery of their instrument. For wind players, one of the "gurus" was always Joe Allard who was a Juilliard, NBC/Toscanini based "classical" player who was revered by many prominent jazz players. From that standpoint, the approach is always the same no matter what direction a player will eventually take. Technical mastery of one's instrument is necessary no matter what. The player who pursues one avenue or another at some point finds that the emphasis must be placed on certain specific aspects of playing more so than others. As Coltrane1 points out, the jazz player must immerse his/herself in jazz theory; but to no greater degree than a classical player might have to study say, Baroque ornamentation. Entire treatises have been written on the subject as well as many other techniques that a "classical" player must be immersed in to convincinly play certain styles. Incidentally, the idea that a "classical" player has to simply be true to the score is a gross oversimplification. Much great music is at least in part about subtlety, and the extent to which a great classical artist has room for interpretation and bringing his/her own vision of the work to the performance is usually not understood. The point is simply that not only is no one music "better" than another; neither music (jazz nor classical) places more demands overall on the player than the other. This is the point that I think you continue to miss Coltrane1. Your comments suggest a higher plateau of demands on players for jazz. Not so. The reason I continue to come back to this is out of respect for the great enthusiasm that you show towards jazz. At some point in their evolution as players, musicians time and time again point to one of their most important milestones (no pun intended, if you know what I mean): Embracing all worthy music as fully equal in worth and worthy of their respect without condescension nor sense of superiority. Good luck with your playing and growth as a musician. Check out: Murray Perahia, "The Aldeburgh Recital". Sublime piano playing, as introspective as anything I have heard of Bill Evans' including the times I heard him live at The Vanguard. Are you hip to the piano music of Scriabin, Messiaen?
