Re: swinging notes
G'day Rick,
I'm surprised that "learning to transpose in your head" isn't one of the things you're 'sposed to be learning 
Actually, the real history goes something like this:
- At about age 8 or 9 I learned to read treble clef - for piano accordion - I'm a gentleman, I don't play one

- Then I started learning trombone - in a brass band where everything was in transposed treble clef
- Except for the occasional Tenor clef part - which is easy, treat it as transposed treble and add 2 sharps to the key sig.
- Next I started playing in church where everything was in concert treble so I started transposing by hand
- After a while I got to the point I could transpose "on the fly" in my head pretty well.
- Got hold of NWC sometime about here and started transposing the parts by computer instead as I wrote or used parts that weren't simply lead sheets.
- More than 35 years down the track I started in the big band - everything's in concert bass clef - what the hell's this bass clef thing..
?..!!! 
- Took a while but now I'm comfortable in bass clef.
- So now I rewrite all the new stuff at church into bass clef for myself - but I don't transpose on the fly much anymore unless we pull out an old song so I'm a bit rusty
- BUT - if I'm reading chord symbols rather than the staff there's no problem
It's all a matter of practice... And I prefer bass clef or transposed treble. The former 'cos that's what I predominately use now and the latter 'cos I'll never forget it - even my bass clef reading is kinda transposed - you see a note in the second space and think "C", I think "D"... But only when I'm playing, not when I'm working in NWC. It's all a bit wierd really.
