A short stretch of room, then the solo keyboard enters around 0:04 with the aria's opening gesture. Within seconds the melodic pattern becomes reliable; the piece's contract — one singing line over slow harmony — is in place by 0:08.

The melody arches and falls in long phrases, lifting near 0:16 and 0:32 while the lower register walks beneath. A first cadence closes around 0:50 and the playing breathes near 0:55–1:00, then reloads the same material rather than introducing anything new. A longer double breath at about 1:22 marks the strain's end — this opening half is confirmed by restatement, not extended.

Around 1:34 the harmony leans minor, and phrase lifts and falls begin trading more closely. Near 2:00 the opening theme's figure returns inside the new territory — repetition now recalls rather than merely confirms. Motion gathers briefly after 3:00 and eases near 3:19; the section's job is to bring back what was established and move it elsewhere.

Long stable spans from 3:23–3:46 and 3:54–4:06 keep the flow intact while ornaments crowd the line. Intensity gathers from about 4:09; phrases lift at 4:21, 4:32, and 4:41, release near 4:45, then cadential figures step down at 4:50 and 4:59 as the music begins arriving.

The hold loosens at 5:26; between 5:29 and 5:32 the final cadence breaks the running pattern and the gathered weight lets go. Resonance decays into silence by 5:37 — the aria resolves rather than withholding.

One sustained span whose only structural events are breaths, a return, and a single final arrival: here the repetition is the form.
