“Think the harpsichord is an inherently limited instrument, too quiet, too inexpressive, too inferior to a modern piano? That, [Mahan Esfahani] argues, implies asking the wrong question to begin with. Think a harpsichordist must naturally align with an early-music movement that awakened so much interest in his instrument? Wrong. … Think that the harpsichord is exclusively an instrument for the music of centuries past? Wrong.”
