G major
G major is a major scale based on G, with the pitches G, A, B, C, D, E, and F. Its key signature has one sharp, F; in treble-clef key signatures, the sharp-symbol for F is usually placed on the first line from the top, though in some Baroque music it is placed on the first space from the bottom...

 accompaniment. There is a triplet-dominated, agitated transition and the same theme is heard, now in D, with triplet accompaniments; the triplets, not the theme, continue to the end of the exposition, and descend gradually from D down to G major for the repeat, or for the second ending and the beginning of the development, where continuity means the continued rustling of quiet strings, building for a bit by exchanging with more energetic passages, then bringing in faster versions of the dotted rhythms of the main themes. The climax of the development leads to a particularly quiet recapitulation, much varied at its opening from what we had heard originally. In the coda the opening of the quartet, both its rhythm and its major/minor exchanges, get a further chance to play themselves out.

There is a remarkably innovative harmonic passage in the first movement. Between mm. 414 and 429 Schubert prolongs G major with an equal subdivision of the octave using major 3rds. Passing seventh chords in the bass provide a smooth linear progression

 connecting these major thirds, the result of which is a descent in whole tones in the bass-voice cello. The following major 3rd prolongations occur: G(mm. 414-416) E-flat(mm. 417-418) B(mm. 419-420) G(mm. 421-422) E-flat(423-426). In measure 426 Schubert enharmonically reinterprets this dominant-seventh structure, resolving it as a German augmented 6th, thus proceeding bVI-V-I in mm. 427-429.

II. Andante un poco moto

The dramatic slow movement contains much in the way of march rhythm and sudden upward violin glides followed by drops to the lowest string, and again much use of tremolo.

III. Scherzo: Allegro vivace with trio: Allegretto

The scherzo is light-textured, fleet for much of its span, reminiscent of Mendelssohn's trademark scherzos. The scherzo’s trio is a mild accompanied duet, first between cello and first violin, then first violin and viola, then again cello and first violin.
