The Wiener Urtext edition of Telemann's Fantasies is based on the first print published by the composer himself. The few obvious mistakes in the music have been corrected. In the critical notes the editor provides information about the source the authorship and authenticity. The notes on interpretation provide instructive suggestions for the historically informed performance practice. Discussion based on sources from the 18th century (Quantz, Hotteterre and others) about related works is included as well as about the basic aspects of baroque flute playing which, for every flautist, are indispensable.
