Piano Sonata No. 6 (Mozart)
- Rondeau en polonaise (Rondo and Polonaise)
- Tema con variazione (Theme with variations)
A typical performance takes about 20 to 25 minutes.
This sonata is the last of the sonatas that Mozart published in Munich. The piece is subtitled "Dürnitz" as it was written for Baron von Dürnitz, an amateur bassoonist and keyboard-player, who failed to pay for the work. The work was written down during the visit Mozart paid to Munich for the production of La finta giardiniera from late 1774 to the beginning of the following March.
A first version of the beginning of the first movement, written on one and a half pages, was cancelled by Mozart. On the same page, he started anew to write the final version underneath. The thematic material of this opening movement (and to a lesser degree also that of the following movements) is laid out on a more ample, nearly orchestral scale, a departure from the intimacy of the early sonatas. The tremolo effect in measures 13-16 and the unison announcements of the first subject read very much like a piano reduction of an orchestral tutti. The second subject, a supple melodic line, unaccompanied in its opening bar, incorporates a descending chain of first inversions, a favourite harmonic formula of the baroque and classical periods. (There are analogous passages in the subsidiary themes in Gluck’s overture Iphigénie en Tauride and the first movements of J. S. Bach’s Italian Concerto). This functions as a solo passage in contrast to the ensuing tutti entries in m.30. The development moves through a circle of minor keys before the recapitulation begins in measure 72.
Rondeau en polonaise (Rondo and Polonaise)
Mozart called the second movement a Rondeau en Polonaise, so it is a dance. The opening four measures from a kind of dialogue (like the theme of the first movement of the preceding G Major Sonata), and Mozart subjects them to felicitous counter-statement is heightened by Mozart's meticulous dynamic markings.
Tema con variazione (Theme with variations)
The last movement of the Sonata is a pianistically rewarding, cheerful set of variations, which, up to the adagio variation, has the character of a gavotte. It shows Mozart’s special gift for writing variations at its most brilliant. The superficial impression of a diffuse form does not stand up to a closer inspection: it would not be at all easy to omit one of the twelve variations, or to add an extra one. The adagio variation is on special interest to Mozart scholars, for it gives us some insights into his concept of impromptu ornamentation. The autograph is only modestly ornamented, and Mozart presumably embellished it in performance as his fancy dictated. But a richly ornamented version survived in the first edition, published during Mozart’s lifetime, and undoubtedly this embellished version is Mozart’s own work.
