This relates rather particularly to BEBOP ENCLOSURES as a basis for a jazz language: I began to watch some youtube vids once I became aware of bebop enclosures, which happened after striving to play upright bass on and off for years, and then discovering ukulele bass, with a very short scale and rubber strings which sounds so much better than harsh electric bass, and discovering Todd Johnson's Bass Module method. Anyway, as a jazz lover and self-taught music teacher on several instruments (I also had theory lessons and know lotsa "facts" cold, but my hearing is still in need of refinement), I had NEVER understood leading tones or "chromaticism" via other "jazz methods". For 35+ yrs I have struggled to play jazz, and tho I transcribed many solos and bought 400+ books and many CD's, and though I could see notes around chord notes in transcribed solos, I NEVER understood (I hate to say) the "simplicity" of the idea, which is to target important notes in the harmony, via enclosures, and hence make one's solos sound legit. I was amazed, in younger years, looking thru the Omnibook, how Bird could play notes near the important notes of chords, and sound great. But how to do that, I had no clue! I was a victim, sadly, of poor education. (But at least I kept struggling.) There is NO mention of bebop enclosures in a certain free jazz handbook. None in the version I received in early 2020, and none in the many I received in years before. But that cat sells some of the BEST spiritual books which have changed my life, without which I would be VERY lost. All in all, the spiritual path is most important, but I sure wish I coulda made better music along the path of my life. But, I am STARTING NOW to get a grasp, so hey, next lifetime I hope to be able to play "the moment". A song title comes to mind..."I can dream, can't I?" (Look, if A.M. and P.M. would prefer that I edit this, I shall, and you all can delete this part, but my STRUGGLE WAS REAL, AND I HAVE BEEN THAT ODDBALL JAZZLOVER ALL OF MY ADULT LIFE.)
