The Interpretation of Music is a book by Thurston Dart.
It is described by the Encyclopædia Britannica as "the best direct and concise account of the issues of performance".
[1] This book deals with correct performance conventions and procedures relevant to different periods and styles (for example Gregorian intonation, divisions upon parts, French baroque over-dotting, etc.).
It covers these various topics in a chronological order, also giving descriptions of period instruments and their uses.
It is a book useful for those wishing to compose in a more authentic antiquated style, and for those wishing to make performances more historically "correct".
