Hey Mike - I think every recording I've heard was the Am -- but the Dm looks neat as well -- and my ear likes things a litle higher pitched I think.
For a chuckle (and some idea, maybe) try this... go to the dir where I have the various formats of my last pass at the 997 sarabande...
...right click and save a local copy of the .MOV
file to your computer. If you play it back with the quicktim player on your local machine, you can click and hold the FF button on the player and hear it an octave higher (and faster -- more "The Chipmunks Do Bach"
sort of stuff)
If you don't have quicktime, there's a link to where you can download a free copy of the quicktime player on the main "junk" page.
The octave is, of course, higher but I guess the Dm would be close to just between the normal speed and FF speed of the Am version (in pitch I mean) - yes?
OH - also - my score for the 997 Sarabande DOES, in fact, note lower octave for much of the bass line. I guess Dm makes having the lower bass more possible on 6 string --- I guess maybe 8 or 10 strings can handle the extra octave basses ok ??
