When it comes to bagpipe ornamentation, the options of what physically to do with your fingers aren’t great. You can lift a finger off and put it down again, as with the cut or the trill. You can put a finger down and lift it off again, as with the strike or vibrato. You can slide fingers off rather than lifting them. Or you can put lots of fingers down, usually on the tonic, to give the impression of a staccato – in France, the rappel.
