Lately I've been listening to the Suas Leat CD by Swallow's Tail Ceili Band, and especially their box player Tom (or Tommy) Doherty. Its exciting box-driven music ideal for Irish set dancing. Does anyone know what tuning he played on that CD, which I think was recorded in 2011? The settings of all the tunes on the CD suit a D/G box with low B and C natural notes and he doesn't seem to play the chromatic sliding notes you'd usually expect from a semitone box player. I first thought he was playing a one-row D melodeon, but I hear plenty of C naturals (and no F naturals BTW) in the tunes. There are a lot of video clips of the band on youtube but none I saw showed his box in any detail.
NB: this Tom Doherty shouldn't be confused with Tom Doherty (RIP) who played melodeon on a CD called "Take the Bull by the Horns".
