Actually 4 sections. 1) Andante cantabile: lilting 9/8 melody on Récit Hautbois 8' with one or two voices on G.O. Harmonic Flute, and another one or two on Pédale Subbass 16' + Bourdon 8'. 2) Lento: interlude with louder registration. 3) Allegro ma non troppo: Beautfully worked out Fugue with G.O. coupled to Récit. 4) Andantino: The original melody and registration are reiterated, but the G.O. figuration is mostly in sixteenth notes.
