Yes ,very good advice, I find the english suits me the best, Althogh I do play the duet as well. I think the duet hasnt been explored properly for trad irish scottish music yet, the octave unison overlap is very useful,played as either a linear instrument or a chordal instrument, using the left hand sparingly, Iwould give seroius consideration to the Crane Duet IF I was starting again.But at least half an hours practice a day is required on any concertina, and when one practices, take out the difficult phrases and play them over and over till you have them right.
