... seems I am repeating myself! I see I gave a very similar response to this thread almost two years ago!

I've actaully gota lot of experience with this capo placement. As a banjo player in a band that loves odd keys, and frequent changes ... I have learned the hard way about capo placement! The banjo is much more sensitive to capo placement then guitars because of the added variable of the drum head tension changes caused by capo placement. It is safe to say that you must retune every time you move your banjo capo (at least fine tune). I also retune my fifth string with each capo change rather then use a fifth string capo or spikes - so the drum head/tension change is even more dramatic. And finally, I change tunings some when we change keys (G or C tunings typically). Needless to say, banjo key/capo changes are a factor in our song selection - we don't want me fine tuning the banjo all night! I have found with the banjo, though - when the stage sound is good enough, that I prefer retuning by ear, because the other lpayer may be slightly off concert pitch, and if I tune strictly to an electrinic tuner we may have a problem. In this case, I tune to electronics, then "sweeten" to where my ear says everyone else is.

Finally, I remnd the audience that the banjo is meant to sound slightly out of tune!
