What is especially impressive about the Denner alto recorder is its extremely easy response and balanced tone in all registers . A slender and refined tone, characterised by a certain brilliance renders this an ideal recorder for solo playing. An agile instrument that can be easily used in all registers, but is particularly suitable for virtuoso music involving many fast notes, such as in the works of Georg Philipp Telemann. The Denner by Moeck is modelled on a recorder from the "Musikhistorisk Museum" in Copenhagen, considered to be by many renowned recorder makers one of the best preserved instruments made by Denner.
