A long opening gap precedes the quartet’s first sound. The silence functions as preparation rather than interruption: the movement begins by making the first soft string entry feel placed and ceremonial.

The quartet states the hymn theme in a clear, balanced phrase design. The section’s job is to give the whole movement its fixed object: a melody stable enough to be recognized through later redistribution, ornament, and register change. The cadence near the end closes the statement quietly before the first variation begins.

The theme returns in a more transparent setting, with delicate upper-string figuration around the familiar line. The form does not move away from the hymn; it proves that the melody can remain intact while the surface becomes more active and lightly ornamented.

The melody moves into the cello register, broadening the span of the quartet. This section changes the form by relocating the theme’s weight: the same hymn material is now heard from below, while the upper strings answer and support it. The cadence again closes without breaking the variation chain.

The viola takes the theme, and the surrounding writing becomes more chromatic and interwoven. This is the movement’s interior turn: not a new theme, but a deeper re-coloring of the same one, with suspensions and inner-voice motion making the variation feel less declarative and more searching.

The later span keeps reloading the hymn frame rather than abandoning it. Repeated returns matter here because the movement’s form depends on continuity: each pass confirms the theme’s durability under changed distribution and density. The final minutes gather the material back toward closure, easing through phrase drops and releases until the pattern loosens at the end and the quartet lets the movement settle.
