My reference to "previous poster" referred to Steve Gardham who was the previous poster at the time, but a few others intervened!
I am at one with GUEST (unnamed) above: a bit confused by John Adams' posts. In one John adamantly denies that English fiddlers used trebles and rolls, in another he includes a link to an article that discusses the use of these very ornamentations by English fiddlers.An article with which I fully agree(on that point at least).
Earlier on in this thread, for example, John Adams particularly mentions mentions the Englishman William Irwin's tunebooks with approbation. Well, he'll find rolls and trebles in there.
