Here's a nice up-the-neck-but-"open" variation of the A major chord that I learned years ago: make a standard D major, shift it over one string towards the bass side of the fingerboard and up three frets ~ like this:

E-A-D-G-B-E
0-0-5-6-5-0

Thanks to Don for pointing our that the C7 can not only move up two frets to become a less-then-perfect D7, but can also move another two frets further up to become a nice full 6-string E7. I think that's just the kind of thing Susan was looking for in her initial post.

PS to my fellow HTML novices/learners: The code for shifting to that monospaced "typewriter" font is "tt." [bracket]tt[bracket] to start, [bracket]/tt[bracket] to end and go back to the default font (Times). The brackets, as always (on this site, anyway) are the "less than" sign (<) to open and "greater than" (>) to close. Invaluable for making tablature and for ensuring that chord symbols appear above the correct syllables when providing lyrics-with-chords.
