Analysis of Brahms’ First Symphony, Bars 1-9
The beginning of this symphony is incredible. A wash of sound, a constant heart beat in the low voices and timpani, full string section and full woodwinds.
Sitting down to do a harmonic analysis of the opening of this movement, Brahms’ habit of playing with the meter will also play with your mind as you try to figure out which notes in which voice belong to which chord. Above you will see a reduction of the opening of this symphony. It has three main ideas (doubled at the octave). Line one is played by the violins and celli. Line two belongs to flutes, oboes, clarinets, bassoons, Eb Horns (partially), and violas. The pedal C (line three) is played by the timpani, contrabassoon and contrabass, and is also sustained by the C Horns.
The most important road block in analyzing this opening is lining up what the harmonic rhythm is and where the actual chords are. The goal of the following section is to show how aligning line one over the harmonic rhythm established by line two can uncover the underlying harmonic progression in these nine bars. This can be accomplished by eliminating the second quarter note in the first bar of line one, and writing the part exactly as written. To realign the parts at the end, extend the final Bb in measure 7 and the F natural in measure 8 by one eighth note each. This looks like the figure below.
As you can see (and perhaps more clearly hear) this lines up the two parts almost perfectly, allowing for a harmonic progression that is clear to discern, and a regular harmonic rhythm. The progression can be explained thusly (roman numerals reference the key of c minor):
Bar 1 : Beat 1 announces a unison c, implying i. Beat 4 is a vii°/ii. The vii°/ii resolves to a
Bar 2 : II, which over the course of the bar and a quasi voice exchange leads to
Bar 3 : ii (the ultimate goal of the vii°/ii). Beat 4 is a vii° of the next chord which is
Bar 4 : a V7/E. Using root motion by a third, this chord progresses to
Bar 5 : V
Bar 6 : i
Bar 7 : IV
Bar 8 : Beat 1 produces a dominant chord of the next harmony on beat 2, a V7/VII. This chord is transformed on beat 7 by raising the root up a halfstep into a vii°/V.
Bar 9 : V.
When the piece is lined up this way, you do not find a single non-chord tone, except for a couple passing tones in the ascending stepwise sections, and the pedal C that drones throughout.
Brahms, by offsetting line one, has created added even more tension in the first four bars (as if the progression there was not tense enough), and has added a bit of suspense to the seemingly plane V – i – IV turnaround in the middle of these bars. This will also explain why there is a release of harmonic tension when the Ab moves to the G in bar five.
I hope that this little analysis provides a clearer picture of the opening of this great symphony.
