Gaelic folk musicorGaelic traditional music is the folk music of Goidelic-speaking communities in Ireland, Scotland, and the Isle of Man, often including lyrics in those languages. Characteristic forms of Gaelic music include sean-nós and puirt à beul singing, piobaireachd, jigs, reels, and strathspeys.
The six Celtic nationalities are divided into two musical groups, Gaelic and Brythonic,[1] which according to Alan Stivell differentiate "mostly by the extended range (sometimes more than two octaves) of Irish and Scottish melodies and the closed range of Breton and Welsh melodies (often reduced to a half-octave), and by the frequent use of the pure pentatonic scale in Gaelic music".[2]
The emigration of Scottish GaelstoCape Breton has also resulted in a unique strain of Gaelic music evolving there.[3][4] A number of fiddle tunes of Irish and Scottish Gaelic origin have entered the American bluegrass and country repertoires.
The session is a common setting for Gaelic music, where musicians from a given locality gather to play music in a public setting. Gaelic music is also commonly heard at folk festivals, by pipe bands and at competitions such as mods and the Fleadh Cheoil.
In Traditional Gaelic music, the Ionian, Dorian, Mixolydian and Aeolian modes dominate,[5][6] with the keys of D Ionian, G Ionian, A Dorian and E Dorian among those popular with session musicians.[7]
Unlike Classical and Jazz music, modal harmonisation avoids diminished chords, as seen below for the seventh scale degree of the major scale.[8] Seventh chords are generally limited to the II and the V positions of the chord scale.
