Be Bop. I guess it was good for branding purposes, as such catchphrases are in the world of commerce-Coca Cola, Alka Seltzer, Finger Lickin' Good. But the disparity between the serious nature of the music and the phrase attached to it is palpable. An exception can be made for the trickster Dizzy Gillespie, who was as serious as they come, but who knew how to work wordplay into the music (ooh bop she bam, etc.).
Hard Bop. A ludicrous title. There was no harder bop played-in any sense of the word-than that played by Bird, Diz, Fats Navarro and company. If anything, hard bop took its foot off the pedal more often than Bop.
New Testament and Old Testament Basie bands. I haven't found anyone who knows who pinned these labels on the Basie bands pre and after the early 1950's. Why it stuck, I don't know. I'm not saying that jazz is the enemy of the bible-although it certainly has often been seen this way. Let's just say I believe in the separation of church and the jazz estate.
Cool Jazz. First of all, all jazz is cool, no matter how hot it gets. Second of all, this label is used to differentiate East Coast from West Coast jazz, which is ridiculous. A lot of musicians were burning on the West Coast, while Miles, Gil Evans and company were creating the music specifically called Cool in New York City.
Neo Bop, Post-Bop, Neo-Swing. Putting neo- or post- in front of anything demonstrates a chilling lack of imagination.
These locutions are now, happily, in the Dust Bin of History:
Licorice stick (for a clarinet). In the film "Song of the Thin Man", I actually heard Keenan Wynn refer to the instrument as a Jew Stick.
Skins/Tubs (for drums), Popsickle Stick (a reed player's reed).
Hot Lick, Oh, Daddio, Real Gone, Wig Out, Solid Sent, Moldy Fig.
Tacking "-ville" on the end of anything, is, like, hicksville, dullsville, squaresville.
