I completely understand (and agree with) the need to have a "base" fingering system as a place to start from. That said, I'm still perplexed by the use of the #14 draw to play the 'c'. It adds another finger for just one note, and it doesn't decrease the number of bellows changes than one would employ to play a G scale using instead the #21 push. But what puzzles me the most is that Mr. Hill doesn't like the #14 push to play 'B' because of the location of the reed (under the hand) and the resultant change in sound - yet, for the #14 pull ('C'), the reed is located in the same place and clearly (on my two concertinas at least) has a different sound than the right hand 'C'. I'll be studying with Mr. Hill in a couple of months and can get the explanation directly from the source but, still, I'm puzzled by that choice.
