I find when playing irish hornpipes and I have a sequence of two notes that are a major third apart , lets say D B to turn it into a triplet d c b, or d d b[the latterwith either tongueing on the first two notes or glottis glotting]anyone else play irish music on the harmonica and got any different ideas, this d c b is a thing that i do on my other instrument the english concertina.
