Considered one of the leading early-music specialists in Europe, Terence Charlston introduces a unique instrument in his new release Mersenne's Clavichord, a clavichord built to plans and specifications by Marin Mersenne in his 1636 treatise Harmonie Universelle. This collection includes primarily French compositions of the 16th and 17th centuries, and Charleston vividly demonstrates the now rarely heard sound-world of the instrument which was so familiar to the composers of that day.
