Scottish fiddling may be distinguished from other folk fiddling styles by its particular precision of execution and energy in the delivery, for example, the rendering of the dotted-quaver/semi-quaver rhythmic patterns, commonly used in the Strathspey. 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. There is also a strong link to the playing of traditional Scottish bagpipes which is better known throughout the world.
