Although written for 'cimbalo' (harpsichord), Susan Alexander-Max plays the pieces here on the restored Cristofori piano in the New York Metropolitan Museum, one of three extant instruments which their inventor himself called a 'harpsichord with soft and loud'. She plays with the restraint demanded by such a delicate and complex mechanical action, and the sound is charming - warm and plummy in the middle and lower range, more sparkling on top. A most imaginative combination of music and instrument, both revealed as far more than mere curiosities.
