The Flute Quartets

In 1777-78, during his difficult journey from Salzburg towards independence via Mannheim and Paris, Mozart accepted the commission from Ferdinand Dejean and discovered how naturally the flute could sing. These quartets for flute and string trio are conversations in elegant dress, balancing between salon elegance and theatre, music of chambers rather than halls, but with the sparkle of a miniature stage. The city of Mannheim – famous for its disciplined orchestra, long crescendos and expressive wind players – offered a laboratory for colour and balance; Paris suggested fashionable combinations and a preference for variety; Munich brought the elegance of opera; Vienna added the social intelligence of the salon. From these environments Mozart created works in which the flute is not an exotic bird floating above the texture, but a citizen among equals. The pieces from Mannheim set the tone. The quartet in D major KV 285 feels almost like a concerto in miniature: an opening Allegro in which the flute plays a radiant line above a lively string figure, self-assured yet collegial, with the strings answering with swift scales and arpeggios, so that grandeur never becomes dominant. The Adagio shifts into B minor and breathes a nocturne-like atmosphere. With the strings pizzicato – a soft cushion upon which the melody rests – the flute sings an aria that seems both intimate and eloquent, a confiding voice floating between melancholy and comfort. You feel how the young composer, enchanted by the musicians of Mannheim and by the opera in his blood, could make an instrumental line sound vocal without words. The Rondeau returns to daylight, elegant and capricious, with each episode revealing a new facet of the conversation. The quartet in D major is youthful but never childish; its virtuosity is tempered by tact, just as in Haydn's quartets the sharpest wit is anchored by courtesy. If KV 285 is ardent, then the Quartet in G major KV 285a glows. With only two movements and an opening Andante, it begins not with bravura, but with balance. The flute and violin exchange phrases reminiscent of the suppleness of Johann Christian Bach – whose chamber music Mozart cherished and from whom he learned so much about balance and melodic line. The music listens as much as it speaks; viola and cello whisper with a discrete, Haydn-like humour, and nothing is forced. An elegant Tempo di menuetto bows without stiffness to courtly tradition, the trio coloured by a subtle shift in the inner voices. This is a conversation in the spirit of the Enlightenment: measured, genial, intended for both the pleasure of exchange and the presentation of ideas. In such compositions one hears the germ of the equality that would characterize later quartets: the conviction that eloquence in chamber music is collective. The quartet in C major KV Anh 171 (285b) is marked by history, yet nonetheless has an irresistible effect. Probably left incomplete and later supplemented, it nevertheless unfolds with a convincing naturalness. The opening movement, Allegro, is a sparkling game, a spectacle of scales and syncopations that keeps the texture transparent. The second movement, Theme and Variations, becomes a salon of characters: first the flute draws filigree, then the violin embroiders, and the lower strings claim eloquent passages. A variation turns towards minor as if thoughts have slipped in from the garden; another restores a smiling grace. The close adds a subtly comic turn, a wink that lies somewhere between minuet and folk dance. Mozart's mezzo carattere – that fusion of the serious and the playful – is everywhere present. Listeners will hear affinities throughout his oeuvre: the elegant, breathing lines anticipate the wind serenades, and the idea of a variation theatre finds grand resonance in the Gran Partita KV 361, where public grandeur still makes room for personal confessions. During his stay in Mannheim and Paris he also explored fashionable combinations, sketched the Concerto for flute and harp KV 299/297c and discovered that fashion could serve content. After the setbacks in Paris and a hesitant return to Salzburg, he entered Munich with Idomeneo and the Quartet in F major KV 370. The work in F major is chamber music that behaves like a miniature concerto. The opening Allegro sets a noble pace, but within it the solo part must unfold and dance, testing the newly expanded range of the instrument. The development is peppered with friendly skirmishes between soloist and violin, the harmony lively and refined as Mannheim does it. The Adagio switches to D minor and becomes an opera scene without words: the strings speak in half-shadows, the flute answers with tender ornaments, and the pauses feel like breaths between phrases on stage. The finale, a Rondeau in F major, contains playful rhythmic interplay – two-part gestures against a compelling 6/8 beat – before everything ends with a smile. Brilliance and warmth go hand in hand here, just as in Idomeneo grandeur and intimacy float together in the air. At the other end of the journey stands the String Quartet in A major K 298, probably written a few years later for friends and for fun. Mozart calls it, with a wink, a quatuor dialogué. The first movement, Theme and Variations, is borrowed from a graceful song by his friend and publisher Franz Anton Hoffmeister, which is first presented simply and then clothed in increasingly playful disguises. One need not recognize the original to enjoy the wit, for the counterpoint is crystal clear and the camaraderie effortless: the flute ornaments, yields and returns; the strings imitate, tease and applaud. The Menuetto proceeds with restrained grace, but in the trio the flute lets out a mischievous French tune – Il a des bottes, des bottes, Bastien – as if we had suddenly landed in a Parisian salon before composing ourselves again. The Rondeau crowns the joke. The quasi-Italian marking – Allegretto grazioso, ma non troppo presto, però non troppo adagio. Così-così – con molto garbo ed espressione – is a tempo indication that is simultaneously a smile, and the main theme alludes to Paisiello's Chi mi mostra tant'amor. The homage turns to mischief when Mozart plays with timing and accent, a spectacle of playful inventiveness that never breaks the spell of elegance. It is the last of the flute quartets and the most genial – a blessing rather than a farewell. Lines run through these quartets that extend outward. The lustre of Mannheim refers back to Haydn's developing quartet world, where equality in conversation is the norm; Mozart adapts that principle for a group with a nominal soloist, ensuring that the flute never silences its partners. The aria-like slow movements anticipate not only Le nozze di Figaro and Don Giovanni, but also the instrumental song of the Sinfonia concertante and the wind serenades, with their gift for public elegance and personal candour. The adroit finales, whether rondo or variation, reflect the civilized wit of J.C. Bach and look forward to the refinement of the Viennese piano variations; the playful borrowings in KV 298 align with a European habit of quotation that extends from Parisian quatuors d'airs to the salon fantasies of later generations. These quartets carry the atmosphere of chambers: chambers in palaces in Mannheim, apartments in Munich, Viennese houses where music and conversation sat at the same table. The flute here is no pastoral cliché, but a full member of the ensemble, capable of singing with natural suppleness and listening with tact. The strings, freed from mere accompaniment, provide their own commentary – the velvet soft murmur of the viola, the warm anchorage of the cello, the quick assent and occasionally divergent voices of the violin. Mozart derives eloquence from conciseness: repeating notes that breathe; canonic glances that are never didactic; cadences that hold their breath a heartbeat longer than courtesy requires. In the Adagio in D major, pizzicato creates a frame of air, inviting the flute to paint sorrow without rhetoric. In the Andante in G major, phrasing opens like shutters to the twilight. In the variations in C major, character studies unfold with the finesse of a miniature theatre. In the slow movement in F major, opera crosses the threshold soundlessly, and in the finale in A major wit dances on its toes, never raising its voice. The five works invite together a listening experience that proceeds not only from piece to piece, but also from light to shadow and back again. The journey ends where it should, with a smile. But along the way we have travelled a considerable distance – from a winter in Mannheim to a Viennese evening, from apprenticeship to friendships, from the fashion of the world to the measure of the heart. As we hear these quartets now, they still sound like the art of conversation at its best: fluent, candid, elegant and human. They remind us that Mozart, even when the subject seems trivial, knows how to find depth; and when the surface is brilliant, he never forgets the warmth that hides beneath it.
