François-Adrien Boieldieu's output of instrumental music was initially meager and virtually ceased once he became one of the top opera composers in Paris. Be it as it may, his instrumental Harp Concerto in C, also known as Concerto in Three Tempi, proved to be an intricate work that retains a central place in the harp repertory to this day.
The Concerto opens with a festive and fast theme which is followed by a restless melody, all in the late Classical style, seemingly evoking the works of Mozart and Beethoven.
Apparently the creation of this masterpiece was facilitated by the close acquaintance of Boieldieu's, Sébastien Érard, who was a French instrument maker of German origin. Érard specialised in the production of pianos and harps, developing the capacities of both instruments and pioneering the modern piano. His innovative seven-pedal harp allowed each string to be shortened by one or two semitones, creating a whole tone, and this new mechanism demanded a more versatile type of music. Still used by modern pedal-harp makers, this harp allows the player to perform in any key or chromatic setting.
