a jaw triplet,are you serious?,
it is a flick to the right or the left with the jaw,to make a note either a third above or below in the same wind direction.
Steve,You know very well that a critic does not have to play the instrument to criticise, whatever you think of my playing the fact of the matter is ,I have been playing Irish music on the concertina and harmonica for many years I am acquainted with ornamentation and styles, a reasonable enough basis to make a criticism,if you cant take constructive criticism,you might as well pack up.
your playing good though it is lacks drive on two tracks,one way you could improve would be to use octave tongue blocking,this allows you to play in octaves[especially on the sliabh luchra polkas].
