There are two jigs that carry the name “The Gold Ring” (“An Fáinne Óir” in Irish). One is a 7-part jig in G particularly popular with pipers, and the other, a 4-part jig in D Major. This tune is the D Major tune, and it's one of Tony's all-time favourties.
Although this is a D tune, Tony plays it in C with a capo on the second fret. This tune has a wide range of just over 2 octaves, but if your left hand is positioned correctly you should need very little, if any, lateral movement to reach all the notes.
