Onhwy61, makes some outstanding points that are undeniably true. (much as I hate to admit it). Melody lines are indeed what most people listen for, and remember, AND are attracted to.It also is true that the Count Basie variety of Jazz, that includes more melodious standards, and the like, as well as swing is mostly missing, in my preferred bebop genre. Yet, the imagination with bebop is limitless. You can listen to it and discover new perspectives as time goes by. Tunes without improvisational foundation, are also quite valuable, to our musical jazz heritage, but somewhat less interesting at a introspective level. My opinion only...........Frank
