Symphony No. 1 (Beethoven)

Ludwig van Beethoven's Symphony No. 1 in C major, Op. 21, was dedicated to Baron Gottfried van Swieten, an early patron of the composer. The piece was published in 1801 by Hoffmeister & Kühnel of Leipzig. It is not known exactly when Beethoven finished writing this work, but sketches of the finale were found to be from 1795.

The symphony is clearly indebted to Beethoven's predecessors, particularly his teacher Joseph Haydn as well as Wolfgang Amadeus Mozart, but nonetheless has characteristics that mark it uniquely as Beethoven's work, notably the frequent use of sforzandi and the prominent, more independent use of wind instruments. Sketches for the finale are found among the exercises Beethoven wrote while studying counterpoint under Johann Georg Albrechtsberger in the spring of 1797.

The premiere took place on 2 April 1800 at the K.K. Hoftheater nächst der Burg in Vienna. The concert program also included his Septet and Piano Concerto No. 2, as well as a symphony by Mozart, and an aria and a duet from Haydn's oratorio The Creation. This concert effectively served to announce Beethoven's talents to Vienna.

The symphony is scored for the following instrumentation

The clarinet parts are commonly played on B♭ clarinet, as C and D clarinets are no longer widely used. However, there is some controversy over whether they should be played on E♭ instruments instead. The E♭ clarinet's timbre is much closer to that of the C and D clarinets than that of the warmer-sounding B♭ clarinet. The second flute is not used in the second movement.
