Bebop scales, per se, are a misnomer. This particular idea is based upon harmony, progressions, and many other intangibles. Thus, the options become ad infinitum. It is essentially based upon what you know (and can learn) and technique. Bebop is much like a choreographed dance piece.
x=x, depending; on a lot of variables, forseen and/or unforseen. Knowledge, technique, experience and at times, pure balls, make what you improvise, what you say. Bebop will not happen in a vacuum. x must exist.
A lie goes around the world before the truth gets it's shoes on. (Mark Twain)
