Piano Concerto No. 7 (Mozart)
Mozart's Piano Concerto No. 7 in F major, K. 242, is a piece built for three pianos at once. That alone raises a question most listeners never think to ask: who, exactly, were those three pianists meant to be? The answer points to a specific commission, a Countess, and her two daughters. And that backstory explains why the concerto carries a nickname that has nothing to do with Mozart himself. The piece also has a second life. After Mozart completed it for three performers, he came back to it years later and rewrote it for two. That revision is the version most audiences encounter today. How did a work written for three pianos in 1776 become one of Mozart's more quietly interesting concertos, performed to this day in a form he never originally intended?
Countess Lodron commissioned the concerto to be played together with her two daughters, Aloysia and Giuseppa. The nickname "Lodron" stuck to the piece because of this family origin. Mozart finished the original version in February 1776, one of three piano concertos he composed that year. The instrumentation was designed to accommodate three soloists simultaneously: three solo pianos supported by two oboes, two horns, and strings. That particular combination gave the work its unusual texture. The commission itself was a social arrangement as much as a musical one. Writing a concerto that placed a mother and her daughters at three keyboards was a gesture toward a specific household, not a general artistic statement. The daughters, Aloysia and Giuseppa, are named in the source as the intended co-performers, making this one of the more precisely documented commissions in Mozart's catalogue.
In 1780, in Salzburg, Mozart returned to K. 242 and rewrote it. He reduced the three-piano arrangement to two, apparently for himself and another pianist. That rearrangement is the version most often heard in performance today. The revision meant redistributing the keyboard material originally spread across three parts. Mozart was not simply cutting one piano out; he had to rebalance the solo writing so that two players could carry what three had shared. The fact that he chose to perform it himself suggests the revision was a practical one, tied to a specific occasion rather than a broad reconsideration of the work. Whatever that occasion was, the two-piano version outlasted the three-piano original in performance history.
C. M. Girdlestone, writing in his book "Mozart and His Piano Concertos", drew attention to the slow movement of K. 242. He identified a theme there that reappears in later concertos in more developed forms, citing No. 25, K. 503, as a particularly clear example. That kind of thematic cross-reference across Mozart's output is something Girdlestone made central to his analysis. Spotting K. 242's slow movement as an early form of material that matured in K. 503 positions the concerto not as a minor occasional piece but as part of a longer arc of Mozart's pianistic thinking. Girdlestone's comparison gives listeners a reason to pay attention to that movement specifically, and to hear it as a sketch of something that would later grow into a more fully worked-out musical argument.
The first British performance of K. 242 took place on the 12th of September 1907 at Queen's Hall, as part of the Proms series given there by the New Queen's Hall Orchestra. Three soloists shared the keyboards: Henry Wood, York Bowen, and Frederick Kiddle. The conductor was Henri Verbrugghen. Henry Wood is the figure most associated with the Proms in that era, and his appearance as one of the three soloists rather than as conductor is a notable detail. The 1907 premiere came more than a century after Mozart completed the concerto, which reflects how rarely the three-piano version was staged. That performance represents one of the few documented occasions when the original three-piano version was presented publicly in Britain.
Common questions
Why is Mozart's Piano Concerto No. 7 called the Lodron concerto?
The concerto is nicknamed "Lodron" because it was commissioned by Countess Lodron to be performed with her two daughters, Aloysia and Giuseppa. The family name attached to the piece through this commission and has remained its informal title.
How many pianos does Mozart's Piano Concerto No. 7 K. 242 require?
Mozart originally wrote K. 242 for three solo pianos, two oboes, two horns, and strings. He later rearranged it for two pianos, and that version is the one most commonly performed today.
When did Mozart compose Piano Concerto No. 7?
Mozart finished the original three-piano version in February 1776. He later revised it for two pianos in 1780 in Salzburg, apparently for himself and another pianist.
Who performed the first British performance of Mozart's K. 242?
The first British performance was given on the 12th of September 1907 at Queen's Hall during the Proms. The three soloists were Henry Wood, York Bowen, and Frederick Kiddle, conducted by Henri Verbrugghen.
What connection does Mozart's Piano Concerto No. 7 have to his later concertos?
Musicologist C. M. Girdlestone identified a theme in the slow movement of K. 242 that reappears in more developed form in later concertos, particularly No. 25, K. 503. He discussed this in his book "Mozart and His Piano Concertos".
Why is Mozart's Piano Concerto No. 7 usually performed with two pianos instead of three?
Mozart himself rearranged K. 242 from three pianos to two in 1780 in Salzburg, intending it for himself and one other pianist. That revised two-piano version became the standard performance version and is how the piece is most often heard today.
