strike the guitar briskly and you get a wonderful 'skirl of the pipies' sort of sound - what shall we do with the drunken sailor, marie's wedding, step it out mary, as i roved out on a may morning,

in jazz you get summertime fairly easily, st james infirmary, swing it!

in rock you get sultans of swing, and del shannons runaway - but you need to be able to play barre chords for that last one.
