"Mr. Beveridge's Maggot" is an English country dance tune in 3/2 time and G Minor. The parts are played ABB (Sharp) or AABB (Barnes). The parts are not symmetric: there are four measures in the A part and eight measures in the B part.
Mr. Beveridge was a court dancing master who was famous in the 1680's in England and who, along with Mr. Issacs, began devising maggots - distinctive longways country dances to triple-time hornpipes.
A maggot was another name for a dram, a unit of liquid measure, but also meant a small thing of little consequence or a plaything, from the Italian maggioletta. The maggots began appearing in the Dancing Master, ninth edition, of 1695, and the appendix to that edition, The Second Part of the Dancing Master, contains most of the 24 dances attributed to Beveridge. This melody dates to 1696.
It was printed in Barnes' English Country Dance Tunes (1986), Fleming Williams & Shaw's English Dance Airs; Popular Selection, Book 1 (1965), Raven's English Country Dance Tunes (1984), Sharp's Country Dance Tunes (1909) and Barlow's Complete Country Dances from Playford's Dancing Master (1985).
