Apologies if this is a really dumb question but . . .
if a song requires a capo on the 3rd fret for guitar then do you use a capo on the 3rd fret of the uke after transposing the chords to GCEA uke?
I learned a song from printing the pdf off Chordie and it was only when I exported to Chopro that I saw there was a hidden comment to capo the guitar at the 3rd fret. So I tried a capo on the 3rd fret of the uke but wasn't keen on the result.
However, in the case of that song, I play it picking the notes rather than playing the full chords and I do not use the full chord shapes (because I can't do them yet!) and it sounds better to me, played that way, without a capo on the uke.
I haven't tried alternate picking patterns to see if that makes a difference as I already play the song on two ukes, an acoustic concert with high G and an electric tenor with low G and the picking needs to be different for the two instruments already.
Best wishes,
