Query: A classic for serious students of the recorder

First, please do realize that recorders can be serious instruments; there are virtuoso players worldwide, and the American Recorder Society (in the USA, of course) is an organization worth learning about (at least).This book is one of several that a serious student would do well to acquire. Being written by Britons, its terminology differs slightly; their "descant" is our soprano, and their "treble" is our alto.It's apparently been in print for decades; my copy is dated 1961. Guess that qualifies it as a classic!Fwiw, I'm no expert, but did want to help by offering some information about it.
