This paper is a collection of corrections and related thoughts for Bevil's thesis The Welsh Crwth, Its History and Its Genealogy.

In the early years of the nineteenth century, when bowed string instruments were assumed to have reached the apex of their development, there arose among antiquarians and scholars a widespread interest in tracing the ancestry of the violin and related members of the chordophone family. This task proved to be exceedingly formidable not only because of the enormous amount of often obscure evidence which had to be taken into consideration but also because of the manner in which many items of evidence seemed to contradict each other. The issue is still not resolved to the complete satisfaction of every party concerned. Literally scores of different and often conflicting arguments have been advanced, and it could perhaps be justly said that the only furtherance thus far realized has been that of the confusion rather than the resolution of the issue.
