Gang, many thanks for an interesting bunch of responses. Please, keep 'em coming.
cosmosdan Not to mention Glen Morangie, Tal Isker and Johnny Walker. I personally have a 1 1/2 drink sweet spot, but it’s almost impossible to attain without accidentally going one over the line. According to an NPR Jazz Profile about Oscar Pettiford (bassist), he was one of the rare exception of someone who could continue to play well long past the point where Ray Brown would be unable to hold the bass, let alone play it.
F. U. Shakespeare I love Bob Brozman! I’ll take some time to check out some of the others you mention - I’m not a slide guy at all, but I’ll steal from anybody good if I can.
Panurge I’ve always had the utmost respect for anyone who wants to take on the Tabla - it is by far and away the hardest percussion instrument from the purely technical standpoint, and yet the really good ones I’ve heard make it sound absolutely effortless. There just aren’t a lot of teaching aids out there for the instrument, at least not that I know of. My friend Azed plays, and he has something amazing - Alla Rakha stayed at his dad’s house in Brampton one time when he was through Toronto, and his dad got the Master’s permission to video-record his warm-up. Azed then copied that tape and kept the original someplace safe. Apparently, it’s a fantastic warm-up - Azed has worn through two tape copies, and he currently works with a DVD copy…
GorillaMan I’ll check through those. You bring up an interesting point - virtually all of the fundamentals/harmony/theory/counterpoint books I know of were written by pianists or organists. As a result, they tend to proceed in a way that recapitulates how pianists learn their instruments. I don’t know how it is for violinists and other orchestral string players, but for guitarists, this gets quite annoying - we’re working on a harmonic instrument, too, but we approach our instrument in a very different way. I’ve taken to writing my own handouts about the whole she-bang, using the pieces we’re working on as the basis for explaining how harmony works on our instrument. I also make them sing in order to explain how harmony works. Nothing gets the concept of voice leading across faster than having to find the notes (or sing the monotonous alto part!) you just wrote out… Between two violins and two voices in the room, you could do fugues. 
Eureka I used to play handbells in the church, and it was such a prime mind bender; I loved it! The fact that it could be harder to play just two notes on handbells than the whole piece on guitar or piano drove me bananas for months, and when someone couldn’t make it to rehearsal and we had to either miss out notes or redistribute the parts - AAUGH! Then, I don’t really know what triggered it, but we started to bond musically, and we figured out how to really listen to each other without losing ourselves. It became the closest to a string quartet I’m ever likely to experience. I still subject students to that kind of thing in singing, even though it’s even harder to keep a singer from singing someone else’s note.
Cunctator I won’t get a chance to read that for a couple of months, but it’s on the to do list.
I, too, have to thank real live human being teachers for lots and lots of what I’ve learned, and I’ve become less fearful about approaching really good players and asking for a lesson or a master-class. Yeah, I also couldn’t do without lots of gadgets in the studio - the metronome, the tuner, the recording/playback device that runs through the amp (for the guitar).
For singing, I record all my lessons and coachings, and I listen to them and sing along softly while doing day to day stuff like the dishes, the laundry, the packing. Something about the combination of a kinetic activity with the brain work makes them memorize deeper, and I get used to the multi-tasking that I will have to do onstage.
I have my programs, too, like Sibelius, Transcribe, Band in a Box on the PC side, Garage Band on the Mac side.
Perhaps this is just another manifestation of Gear Acquisition Syndrome, or perhaps I am way, way more of a geek (or a sucker) than I thought, but I have the worst time with collecting waay too many DVDs, videos and books with enclosed CDs. I guess I’m the guy keeping Mel Bay in business. They don’t even have to serve any didactic purpose or even be very high quality - if it’s a performance film of just about any jazz guy, I want to see it at least once. I’m not even talking about scores, sheet music, books of repertoire (got lots of that, and lots of duplicates so I can compare Segovia’s fingering to Bream’s to Manuel Barrueco’s), but commentaries, biographies. Those Jody Fisher Art of Solo Guitar books with the CDs - one of the most fun things about them is I started cribbing and then transcribing the CDs and comparing them to what was already written as a way of woodshedding my transcription. When I see something that is totally beyond me, like the George Van Eps 3 volume Harmonic Mechanisms for Guitar or the Mick Goodrick’s Mr. Goodchord’s Almanac of Guitar Voice-Leading , I just get a twitch in the wallet. Am I the only one?
That’s all for now, many thanks to all of you, I am on vacation and I am missing a very inspirational sunset. I have to go listen to the lake and the wind sing in different meters at the same time while the sun and the moon chase each other to the horizon.
Talk to you tomorrow, M. le Ministre.
