I think I understand that one thing a capo allows me to do is maintain the key of a song but use different cord shapes. (Easier chord shapes). But what I cant get straight in my head is if I learned a solo without the capo, does that change the fret locations I play the solo when I play it with the capo on?

example: If I play a solo with no capo and the solo starts on 6th fret, then want to solo over the same song with a capo on the 3rd fret. Do I move my starting solo note up 3 frets also? I think not because the "key" should be the same and the notes on a fretted string should be the same capo or not, but I not sure.

Thanks for the help.
