As well as playing on violin and Hardanger fiddle, Caoimhín Ó Raghallaigh plays an instrument made by Norwegian luthier Salve Hakedal, a fiddle with five bowed strings and five sympathetic strings, a cross between a Hardanger fiddle and a five string violin or viola d'amore which he calls a Hardanger d'Amore.. Ó Raghallaigh uses crosstunings or scordatura, and uses baroque and transitional bows made by Michel Jamonneau. Ó Raghallaigh also used to play a Viola Pellegrina Pomposa by American luthier David Rivinus, a highly asymmetrical five-string viola. Caoimhín also plays tin whistle, flute and uilleann pipes, having been taught whistle and flute by Co. Clare flute-player Michael Tubridy of The Chieftains and Ceoltóirí Chualann.
