Scottish fiddling, even to many an untrained ear, can be distinguished from other Celtic and folk fiddling styles by its particular precision of execution and energy in the delivery, particularly noticed in rendering the dotted-quaver/semi-quaver rhythmic patterns most common in the Strathspey, for example. Christine Martin, in her Traditional Scottish Fiddling players guide, discusses the techniques of "hack bowing", "the Scottish Snap", and "snap bowing". These techniques contrast quite sharply with the most common bowing patterns of Irish fiddling. The style has a very large repertoire consisting of a great variation of rhythms and key signatures, arguably more than in related styles. There is also a strong link to the playing of traditional Scottish bagpipes which is better known throughout the world and is a chapter of its own.
