Symphony No. 1 in C major, Op. 21

The symphony opens with a joke: a chord that seems to be in the wrong key, wandering for several beats before landing in C major. That kind of harmonic mischief runs through the whole piece.

I. Adagio molto, Allegro con brio: A slow introduction full of unresolved chords gives way to a brisk, energetic main section built on crisp, repeated-note themes tossed between strings and winds.

II. Andante cantabile con moto: A gentle, songful movement in a relaxed tempo, quieter and more lyrical than the outer movements, with a light march-like accompaniment.

III. Menuetto, Allegro molto e vivace: Labeled a minuet, an old-fashioned courtly dance, but played so fast and with such sudden dynamic jolts that it already sounds like the driving scherzos of Beethoven's later symphonies.

IV. Adagio, Allegro molto e vivace: Another joke to start, a single violin line creeps upward note by note as if the orchestra is warming up, before the full ensemble bursts in with a fast, good-humored finale full of rushing scales.

Listeners familiar with Haydn and Mozart will recognize the vocabulary, the same size orchestra, the same balance of wit and grace, but will also hear Beethoven pushing at the edges: louder outbursts, longer buildups, and harmonic detours that keep resolving in unexpected places.

Beethoven completed his First Symphony in 1799 and 1800, by which time he was already an established piano virtuoso and composer of chamber music in Vienna, though he had not yet ventured a symphony. He led the premiere himself on April 2, 1800, at the Burgtheater in Vienna, on a concert that also included works by Haydn and Mozart, composers whose symphonic language clearly shaped this one. Early critics found it inventive but noisy in places, with one Leipzig reviewer objecting to its free use of wind instruments. The symphony established Beethoven as a composer capable of working within, and quietly testing, the Classical symphonic tradition he inherited, setting the stage for the far more radical symphonies that followed.
