The notation is not the music
Barthold KUIJKEN

Written by a leading authority and artist of the historical transverse flute, The Notation Is Not the Music offers invaluable insight into the issues of historically informed performance and the parameters—and limitations—of notation-dependent performance. As Barthold Kuijken illustrates, performers of historical music should consider what is written on the page as a mere steppingstone for performance.
Only by continual examination and reexamination of the sources to discover original intent can an early music practitioner come close to authentic performance.
