Harpsichord Day in Ann Arbor. Ed Parmentier played for about 3 hours, his students gave concerts and free lessons at the same time. There was also a fretted clavicord to try. This instrument is based on an 18th Century Dulcken.
That is a gorgeous instrument. I recently saw a video of someone playing one of these, one hand on the top keyboard, the other below. It looked really complicated!
