Sonata Form - Beethoven's Symphony No.1 1st Movement

Introduction

This is an unusual opening, considered a 'musical joke'. It doesn't affirm the main key, but instead we hear a perfect cadence to the subdominant, an interrupted cadence in the relative minor, and a perfect cadence in the dominant; the key of C is not firmly established until the exposition. Bars 9-10 give an excellent example of Beethoven teasing the listener into expecting to finally receive the perfect cadence, and instead are given another interrupted cadence.

Exposition

This is a lively theme marked allegro con brio. The rising semitone is a key feature in this theme, which is also based on the tonic triad. The approach and cadence chords up to bar 33 show how the brass instruments at the time were limited to the harmonic series.

We then hear a modulating (key-changing) transition. The wind section supports the strings, and are given a clear identity and role. Several bars feature a tonic pedal played by 2nd bassoon, cello and double basses. This themes quaver motive is used again here in a sequential pattern, leading to imitation between woodwinds and strings.

The second subject then arrives, presenting the opportunity of another important role for the woodwind instruments. There is lyrical imitation between flute and oboe, one begins immediately when the other finishes. This is clear to hear, providing lyrical contrast from the 2 instruments, a departure from the earlier string dominated melody. Use of syncopation in this section helps to give rhythmic momentum. The lyrical theme is stated again, this time with the violins taking the lead, imitated by the flute and oboe together. A strong semiquaver-crotchet theme brings a sense of purpose back to the music, then the second subject theme returns, albeit in a different guise to before.

There is a sudden change of character, the oboe plays a mournful melody over a modulating bass melody, which is using the second subjects primary motive again. This is followed by a codetta, which makes use of the theme used in the first subject. After a perfect cadence, there is a short wind phrase that links back to the exposition, and after the repeat to the development. This second time, a forte dynamic marking, and a tertiary shift (moving to a third from the expected chord) to A major mark the arrival of this development section.

Development

Here Beethoven uses material from both the first and second subjects from the exposition; the main motive from the first, and the syncopation idea from the second. This fusion of ideas traverses the circle of fifths, passing through A,D,G and Cm. The rising staccato crotchet figure used at the end of the first subject is now given prominence, being passed back and forth throughout the orchestra, showing off the various instrumental timbres. This is subject to its own modulations, making its way through Fm and Bb Major. The dotted rhythm from the first subject motive is used again now, passed between the layers of the orchestra before being extended into a scale-like passage, first heard in the slow introduction. A steady descending semibreve dominant-seventh arpeggio leads the tonality back to C major, and into the recapitulation.

Recapitulation

The first subject makes a return here in the tonic with all the woodwinds and strings playing the melody in octaves, and the brass and timpani emphasise the tonic note. After the supertonic restatement in the same orchestration, the chromatically rising wind chords are further extended, and Beethoven fundamentally alters the transition passage. He then restates the importance of the woodwind family of instruments by bringing back the oboe/flute dialogue section. The recapitulation then follows in the manner of the exposition, culminating in a perfect cadence in C Major. This bright tonality is immediately darkened with arrival of  Eb, heralding the key of C minor, and the return of the bass melody. The exposition is followed through to the coda, although it is a period of tonal unrest.

Coda

Beethoven makes further use and development of the first subject here. After a series of modulations, there is a cadential 6-4 (chords Ic - V) into C Major, regaining the tonic, and this chord is used until the end, reinforcing the tonic key.

My Response

Prior to undertaking this exercise, I was already familiar with several symphonies, and had a working knowledge of basic sonata form. Although I have analysed some piano sonatas before, I hadn't previously attempted it with a symphony. I found it very hard work, and more difficult to hear recurrent themes and ideas than on piano. With practice I expect that this will become much easier.

It was interesting to see how Beethoven recycled melodic or rhythmic fragments, either restating them exactly, varying them in terms of pitch, instrumentation, dynamics etc, or extended them. This reuse of musical ideas ties the whole movement together, so it feels like a cohesive whole, rather than several smaller sections stuck together.

I found this video analysis and this written analysis very helpful when undertaking this exercise. I also followed along with a score downloaded from IMSLP.
