Brown: The Recorder - A Basic Workshop Manual

This invaluable book gives useful information on how to keep your recorders in good condition, to do minor repairs, and, above all, how to improve the tuning. Comprehensively illustrated with photographs, as well as some line illustrations that take away much of the mystery about recorder acoustics.

The book manages to be rigorous and scientific, with diagrams showing, for instance, which part of the bore affects which notes, but is eminently practical, and everything is clearly explained.
