ok, so I finally busted my own butt enough after cracking open my Simandl books again for dbl bass, this evening I opened up my Charlie Parker Omnibook and went embarrassingly slowly through Scrapple.
well, all I have to say is DO IT TOO!!!

It's nice to reacquaint myself with 4 string(mainly been using 5s and 6s for a long time) electric as well as reacquaint myself with reading and playing between the 7th and 12th fret ON ALL STRINGS. Sheesh, I feel like such a dope sometimes, but I tell ya, it's a good thing and so worth the humiliation
and even at the slow tempos without rhythmic consideration just merely wanting to get the notes right, Bird's playing just screams of his genius and creativity. worth it no matter what style you play (or however fast or not you eventually get the tunes going)
