The piece uses an arch form, employing and then inverting , expanding, and varying a stepwise ascending melody. It is in the key of B Flat minor and is in 4/2 time, although the meter varies throughout.

The long, flowing melodic line moves freely between the voices in the string choir; for example, the first section of the Adagio begins with the principal melodic cell played by first violins, but ends with its restatement by violas, transposed down a fifth. Violas continue with a variation on the melodic cell in the second section; the basses are silent for this and the next section. The expansive middle section begins with cellos playing the principal melodic cell in mezzo-soprano range; as the section builds, the string choir moves up the scale to their highest registers, culminating in a fortissimo-forte climax followed by sudden silence. A brief series of mournful chords serve as a harmonic transition to return to the tonic, reintroducing the bass section. The last section is a restatement of the original theme, with an inversion of the second piece of the melodic cell, played by first violins and violas in unison; the piece ends with first violins slowly restating the first five notes of the melody in alto register, holding the last note over a brief silence and a fading accompaniment
