A harpsichord concerto is a piece of music for an orchestra with the harpsichord in a solo role (though for another sense, see below). Sometimes these works are played on the modern piano (see piano concerto). For a period in the late 18th century, Joseph Haydn and Thomas Arne wrote concertos that could be played interchangeably on harpsichord, fortepiano, and (in some cases) pipe organ.
