Hm...Skiffle....As a teachester myself I ought to point out that it plays Bass notes, not a musical style.
I actually prefer Blues, slow and smooth. Of course it will play anything you like. I have modified mine with a sliding Capo around the pole and string to set the range without breaking the fingers. I once saw a 4 string version with each string tunes to a different note. The player was quite surprised that over an octave and a half can be got from only one string.
