13 The pieces as written have no clef, no key signature and only four lines to a stave: as the pieces are in the same key, using the same eight notes, the clef and key signature are redundant; the bottom line is not needed since the tunes never reach lower than a G. The four-line stave has a precedent in the William Dixon manuscript from the early 18th century, which was deduced by Matt Seattle to be music for a similar nine-note instrument, the border pipes; see William Dixon, The Master Piper: Nine Notes that Shook the World: A Border Bagpipe Repertoire, ed. Matt Seattle, 2nd rev. ed (Peebles: Dragonfly Music, 2002).
