Franois Couperin’s Concerts Royaux (1722) and Les Nations (1726) use open scoring, indicating that they could be performed by whatever instruments were at hand. + He later confessed that he himself preferred to perform them on two harpsichords. + This suggestion had to wait for these two CDs to be taken up in a recording (the second CD is being readied for future release). + Also presented are a number of his Pices de clavecin, also in rarely heard realizations for two harpsichords.
