The penorcon is a plucked string instrument with nine courses of double strings,[1] depicted in the treatise Syntagma Musicum (17th century) by Praetorius.[2] The sides of the instrument are scalloped and sometimes the resonance soundboard has no holes. In relation to the bandora, its body is a little broader, and in length, it is somewhat lesser. Its neck or fingerboard is quite wide.
This instrument uses the following tuning: G′– A′ – C – D – G – c – e – a – d′.
