If you’re at all familiar with the Indigo Girls, that’s the chord progression for the chorus of “Pushing the Needle too Far” off of their CD Nomads,Indians Saints.
The song also uses the following chords as well:
C9*=x02030 *that’s what the songbook calls it, but it seems to be more of an A7sus4 to me
This song is written in the key of G (the F# is made natural for the F6add9) but you could also do it in the obvious Em and to expand on your keys, you could easily do it in C or Am.
For more progressions, don’t forget that just pulling one finger off or moving it to a different fret can create a nice effect. Take that F6add9, for instance, and move it from xx3233 to xx3213 to xx3203 to x32003 to 320003 to 320013. Or playing with the bass note like xx3233 to xx2233 to x3x233 to x20233.
My recommendation is to learn scales a bit, it helps when trying to play within a key and knowing which notes will fit in the key. However, to me, nothing sounds better than a bridge to a song that finally breaks the key (like playing an Am in the song above and then moving it up to an A major.) It just really adds a great amount of tension. YMMV.
You can try Bm7 with a different fingering: xx4432.
I’d generally play your three chords in the key of G. Particularly with the guitar, since the G and D are suspended through all three chords. And, doing them in the sequence you list them gives you a bVII, IV, I, which is very very common (and thus familiar) to the ear.
I’ll second all the other suggestions of chords that will fit. I particularly like the E- with the high D and G, and to continue with that suspension I’d suggest possibly a Dsus7 (x00213).
Another fun thing to try would be to take each of your original F and C chords and do some bass walk-downs with them to see how they sound. Thusly:
For the F
xx2233 (for this you’d want to swith the strings that your pointer and middle fingers were on for the previous chord)
For the C
x20033 (likewise here, switch to use your pointer on the A string)
Hey! Look at that. Looks like I’m not completely talking out of my ass.
Anyhow, CuriousCanuck, it’s not that difficult to play that Bm with the muted 4th string. When you’re fretting the 2 fret of the fifth string, lean your finger over so it just touches the fourth string. It actually should feel fairly natural and be easier to play than a cleanly fretted 5th string and open fourth string.
