The Knockdhu

Puirt à beul (literally "tunes from the mouth") is a traditional Scottish Gaelic singing style in which rapid-fire Gaelic texts or vocables are fitted to the melodies of instrumental dance tunes such as reels, jigs, and strathspeys. Historically used to accompany dancing when instruments were unavailable or discouraged, puirt à beul functions as a rhythmic stand‑in for fiddle, pipes, or accordion. Its crisp consonants, lilting nonsense syllables, and tightly articulated dance rhythms make it ideal for solo a cappella performance, small group call‑and‑response, or to teach and transmit instrumental repertoire by ear.
