This is really for Ed, but heck, welcome anybody who cares--
Bebop tuning doesn't change most of the harp--all the draw notes stay the same, and you can still play a C major scale without using the button.
The note that is changed is the four hole blow, on both notes (slide out and in).
Since a lot of people use blow hole five for the C (or draw button 4), that note on that hole doesn't mess much up.
Now you have a Bb as a slide out note--which means you can play an F scale without using the button--draw 2, blow 3, draw 3, blow 4, blow 5, draw 5, blow 6, and the final F on draw 6.
And Bb is remarkably more legato--
Blow 4, blow 5, draw 5, draw button 5, draw 6, blow 7, draw 7 and the final Bb either on blow 8 or as draw button 7 (I like draw notes).
