Backing and the piano
I’ve been listening to more recordings of diddly music with instruments beyond the fiddle, and many of these are the older recordings in various compilations
One thing that I am hearing when a piano player is on the recording is chord patterns that resemble “I Got Rhythm” or jazz piano voicings similar to the pre-bop era of the 30s
What I am hearing is the progression I-vi-ii-V played over sections where the tonic chord would sound for 2 bars
Then I hear clearly a I-I7-IV-iv in inversions with the bass line decending from the root down to the V chord as the backer works to bring the phrase home
At first I thought this was just because the record studios in New York put their own rhythm section players on the track with the Irish musicians. That was a common practice back then, and these guys would probably lean on what they knew, especially at the tempos that the Irish songs are played at.
Then I got my hands on “An Historical Recording of Irish Tradiditonal Music From County Clare and East Galway” with Paddy Canny and P.J. Hayes and I heard the same things in the piano backing.
So did Irish folk music get influenced by the swing era piano players of the 1930s when the records made by Irish musicians in New York found their way back to Ireland?
Are these patterns of chord substitution used by backers on other instruments?
Just how traditional is the piano in Irish music?
