Where to put capo

All but one (Bb) of the chords you listed have open shapes that don't require a barre/capo:

Dm xx0231

Bb x13331

C x32010

Asus4 x00230

A7 x02020

I think no capo at all would be easiest, considering the chords. You'll just have to work on that Bb :)

When I find that the chords seem too difficult, I too try transposing the song (shifting all the notes) up or down until I have chords I can deal with. I'm not good at transposing chords on the fly in my head, so I often use a transposing tool such as this site. These sites allow you to paste the entire song into a window and shift the key up or down. In this case, Asaph might be right in saying that the chords you've listed may be easier than other alternatives, but you can certainly try out a tool like this to see for yourself. If the song is meant to be played without a capo, I usually try transposing down first so that if you find a key that is easier to play, you can use a capo to get back to the original key.

My advice: 1.) Print a transposition chart which gives directions on where to place your capo to change from a particular key to a desired key. 2.) Learn how to use your capo through a YouTube video or visit www.justinguitar.com He's sure to have something there to help. 3.) ALSO, I am not sure about your song being in the key of F Major, because the Asus4 and A7 chords seem out of place. Isn't A minor in the key of F? Isn't Am the 3rd degree of F? Isn't A7 a major chord? I'm curious about the inclusion of those chords. 4.) Also, it sounds like you got stuck using somebody's piano music. I would just determine in what key I want to sing (unless you have a separate vocalist who wants the song in the key of F). For example, if I want to sing in the key of A, I could place my capo at the 2nd fret and play the song using G-shape chords. In F, the notes are F G A Bb C D E. The chords are 1=F 2=Gm 3=Am 4=Bb 5=C 6=Dm 7=Edim. So, in G, you'd play G=1 Am=2 Bm=3 C=4 D=5 Em=6 Fdim=7. This is making use of Nashville Numbers, somewhat. I highly recommend learning and using this approach to creating a single chord chart for all musicians in the band, especially if you play regularly with the same people. 5.) Another, tricky alternative, that I'M NOT CERTAIN WOULD WORK is this: Place the capo at the 5th fret. Then, use a C add9 shape to play the F Major chord (that's X87O88). For your C, play 87OO88 (That's a G Major shape). For the Bb, I'm not sure. I think a possibly serviceable Bb could be XX8788--it's high and sweet, but it might work (It's more of a Bb6add9, but that's a valid substitute for Bb major.) Am=O22OOO You might be able to work out the others. I know this last bit is rinky-dink advice, and I'm basically going Ross-Perot on you as I shoot from the hip, but I think this is the way to make that guitar your own. Float these ideas by a trusted brother and see if they have something better. (I would absolutely consider determining your singing key, then use the capo and comfie chord shapes to make it happen.) PEACE!
