In this video I am talking about the potential of the Helder Tenor, which is based on a new bore, an extended key system and a flexible block system called Sound Unit.

Music aesthetics from today demand following capabilities from our instrument from today:
extended pitch range
balanced and flexible volume
dynamic possibilities
increased tone colour variations

This is the reason, why Maarten Helder wanted to set new standards in recorder making and to bring new dimensions into modern recorder performance practice.
