"The Ace and Deuce of Pipering", in Gaelic “Aon's Do Na Piobaireacda” or “A hAon sa dó na píobaireachta” is an Irish set or long dance in cut time and G Major/Mixolydian.
The parts are played AB (Joyce) or AABB (Mulvihill, O’Neill).
The title refers to the highest quality of performance on the Uillean pipes and is taken from playing cards. The tune was considered by antiquarian P.W. Joyce (1873) to be "the perfection of music when well played on the bag-pipes, and its correct performance was believed to be a sufficient test of the instrumental skill of a piper". Joyce, who transcribed the melody in 1853 from the whistling of John Dolan (Glenosheen, County Limerick) specifies hornpipe time for the melody.
It was printed in Cotter's Traditional Irish Tin Whistle Tutor (1989), Howe's 1000 Jigs and Reels (c. 1867), Joyce's Ancient Irish Music (1873/1890), Mulvihill's 1st Collection (1986), Krassen's O'Neill (1976), O'Neill's Music of Ireland: 1850 Melodies (1903), O'Neill's Dance Music of Ireland: 1001 Gems (1907), Reavy's The Music of Corktown, Vallely's Learn to Play Tin Whistle with Armagh Pipers Club, vol. 3.
