B/C & C#/D - differences and similarities - Part 1

First in a series of clips looking at the differences in playing B/C and C#/D accordions in Irish music. Not an attempt to establish the superiority of either! Part 1 - general intro, and a look at the keys of D major and E minor (E dorian). Just scratching the surface of the question really - I'm not an expert. Comments welcome...
