INSTRUMENTS OF (OR CLOSELY ASSOCIATED WITH) ENGLAND
Northumbrian Bagpipes (bellows blown), Leicestershire Bagpipes (mouth blown); English Concertina, Anglo Concertina, Duet Concertina (and important developments to – if not inventions of – other key-boards, such as piano and organ, have also occurred in England); Dital Harp/Harp-Lute, English Cittern; English Flageolet, Penny Whistle, Recorder/English Flute, Pipe and Tabor (old Morris accompaniment), Bells, Brass, and (a recent one) the Stylophone
Footnote: during the Athens Olympics ceremonies, the Greeks, pleasingly, presented their bouzoukis: I wonder how-many of the above instruments - and dances - will be shown at the London Olympics..? (From here.)
SOME GOOD NEWS ON THIS...
Given a "match that" from BBC Beijing Olympics presenters, Seb Coe just answered "5000 Morris dancers".
