Wolfgang Amadeus Mozart was born in Salzburg in 1756, the son of a court
musician who, in the year of his youngest child's birth, published an influential
book on violin-playing. Leopold Mozart rose to occupy the position of
Vice-Kapellmeister to the Archbishop of Salzburg, but sacrificed his own
creative career to that of his son, in whom he detected early signs of
precocious genius. With the indulgence of his patron, he was able to undertake
extended concert tours of Europe in which his son and elder daughter Nannerl
were able to astonish audiences. The boy played both the keyboard and the
violin and could improvise and soon write down his own compositions.
Childhood that had brought Mozart signal success was followed by a less
satisfactory period of adolescence largely in Salzburg under the patronage of a
new and less sympathetic Archbishop. Like his father, Mozart found
opportunities far too limited at home, while chances of travel were now
restricted. In 1777, when leave of absence was not granted, he gave up
employment in Salzburg to seek a future elsewhere, but neither Mannheim nor
Paris, both musical centres of some importance, had anything for him. His
Mannheim connections, however, brought a commission for an opera in Munich in
1781, but after its successful staging he was summoned by his patron to Vienna.
There Mozart's dissatisfaction with his position resulted in a quarrel with the
Archbishop and dismissal from his service.
The last ten years of Mozart's life were spent in Vienna in precarious
independence of both patron and immediate paternal advice, a situation
aggravated by an imprudent marriage. Initial success in the opera-house and as
a performer was followed, as the decade went on, by increasing financial
difficulties. By the time of his death in December 1791, however, his fortunes
seemed about to change for the better, with the success of the German opera The
Magic Flute, and the possibility of increased patronage.
The piano quartet, which reached its eighteenth-century apogee in the
two quartets of Mozart, had its origin in the keyboard concerto, here in the
reduced instrumentation of a chamber concerto, as in the work of Mannheim composers
or of Johann Christian Bach, some of whose keyboard sonatas Mozart had, as a
boy, transcribed as chamber concertos, accompanied by two violins and bass. In
Vienna he wrote two piano quartets. The first of these, the Piano Quartet in
G minor, K.478, bears the date 16th October 1785 and was completed on that date
in Vienna, to be published there by Franz Anton Hoffmeister. By 20th November
Mozart was writing to Hoffmeister with some urgency, seeking money. By 2nd
December Leopold Mozart, in a letter to his daughter, gives news of the receipt
of the work, together with copies of the quartets Mozart had recently dedicated
to Haydn. In the following August he included the quartet in a list of
compositions sent to Sebastian Winter in Donaueschingen, from which it was
hoped that Winter's employer, Prince von Fürstenberg, would make his choice.
This choice did not, in the end, include the Piano Quartet. It was said
that Hoffmeister complained that he could not sell the new work, intended as
the first of a set of three, because it was too difficult, and that he allowed
Mozart to keep the advance he had received for the whole commission.
The key of G minor is a dramatic one and the Piano Quartet starts
with a united opening figure, to which the piano offers a reply. The
re-appearance of the opening figure elicits a further version of it from the
piano, returning in what immediately follows. The piano introduces the B flat
major second subject, to which the string instruments have something to add,
the substance of this taken up by the piano. There is a central development,
with versions of the opening figure of the movement leading to the
recapitulation and the concluding section, with its emphatic ending. The piano
introduces the B flat major slow movement, its rapid figuration passed to the
violin in accompaniment, with a secondary theme in the dominant, making its
first appearance with the string instruments. The final Rondo is in G
major, its principal theme first stated by the piano, before being passed to the
violin and viola, an octave apart. A secondary episode in D major finds a place
for triplet rhythms in music fertile in melodic invention that seems, as so
often, to be more than prodigal with its material. The quartet, as its choice
of opening key suggests, is a demanding work, starting in tragedy but ending in
sheer delight.
The Piano Quartet in E flat major, K.493, was completed on 3rd
June 1786, a month after the first performance of the new opera The Marriage
of Figaro. It was published by Artaria in the summer of 1787. The first
movement opens less ominously than that of the earlier quartet, allowing
delicate contrast between the piano and the other instruments, now even more
closely integrated in the chamber-music texture of the work. The piano begins
the second subject, which is soon taken from it by the violin, which has more
to add, before the exposition is completed. The development makes further use
of the figure that opens the subsidiary material, before the recapitulation.
The slow movement is an A flat major Larghetto, its gentle principal
theme introduced by the piano. The tripartite structure again finds room for
subtle interplay between the instruments, with the piano never allowed to
overwhelm its partners. The quartet ends with an Allegretto, a Rondo with
rhythmic variety in its contrasting episodes, rich in its melodic material, if
marginally less demanding than its predecessor.
