Máire Rua, translated as “Red Haired Mary”, is a slip jig in G.

The B Part of the tune moves into a D Mixolydian mode but as this mode contains the same notes as G Major, that is one sharp (F#), there is no need to change the key signature. The tune moves back to G Major for the last bar of the tunes, which is in fact identical to the last bar of Part A. Tony often pairs this tune with a slip jig we looked at in Lesson 16, Na Ceannabháin Bhána.
