But to return to the original question, as the Rhapsody In Blue was reportedly conceived at the piano, might not the slur have been Ferde Grofe’s idea anyway ?
Good point: it sure could have been. It's been a long time since I've played a reed instrument, and I don't remember how to do smears, if I ever did. IIRC you can cheat a little with the embouchure, a tiny bit, but it's still mostly fingered, I'm pretty confident in saying.
Yeah, I guess it wouldn't really matter much to either doing a Mach-10 chromatic scale or a gliss with one hand on the white keys and the other on the black keys. (If it is a true chromatic scale: I don't think I'd have luck finding my copy at home, so please feel free to discard whatever I say that's not accurate!)
Probably like most people I've heard this piece any number of times, but just from vague memory, I don't remember that the gliss/chromatic scale is all
that fast, and I don't remember it being necessarily absolutely uniform in rhythm (close, but some micro variations, is how I remember it best).
I just think the double-handed gliss looks more awesome!
