Reconstruction of the clavichord described by Marin Mersenne in "Harmonie universelle" (1636) and expounded on by Peter Bavington in "Reconstructing Mersenne's Clavichord" (https://www.peter-bavington.co.uk/Mersennepaper.pdf). Uses Mersenne's Laws to calculate the sounding length of each string, and supports two different temperments: quarter-comma meantone and equal temperment using Mersenne's proposed semitone ratio.
