Etymology: Obaireachd is the Scottish Gaelic word for the ornamented variations, or "embellishments," that a piper plays on a pibroch, the classical form of Highland bagpipe music. The word comes from Gaelic "obair," meaning "work" or "labour," so its literal sense is something like "working" or "a piece of work." That makes sense for a form that is built by taking a short theme and elaborating it through successive variations, each one more intricate than the last. In practice, obaireachd was one of the standard names for the variation sections of a pibroch, and it is closely tied to the piobaireachd tradition, which is often called "the big pipe music" or "ceol mòr." Pipers in the classical tradition learned these variations as a structured repertoire, and the term came to name the decorative passages that set a piece apart from simpler dance tunes. The word is therefore less a general term for music than a precise name for a particular kind of elaborated playing.
