Bach: Concertos For Two Harpsichords

The practice of composing for two keyboard instruments, very common in the illustrious Bach family, naturally achieved its apotheosis with Johann Sebastian, whose three concertos for two harpsichords are performed here by Olivier Fortin and Emmanuel Frankenberg with the Ensemble Masques. These works, particularly the concertos in C minor, are among the composer's most admired. They suggest a conception of the concerto specific to Bach: rather than a dialogue between several individual entities, the piece presents a subtle intertwining of melodic lines and blurs the distinction between solo and tutti parts by making them respond to and quote each other, thus illustrating the principle of harmony dear to the composer.
