[Begin with muted strings and quiet piano chords descending like falling autumn leaves] [Allow a solo oboe to introduce the principal Deveron theme with unhurried phrasing] [Use gentle broken piano arpeggios to suggest the steady movement of the river] [Keep percussion absent during the opening third to preserve the stillness of the landscape] [Introduce clarinet and bassoon countermelodies that intertwine like river bends] [Permit the piano theme gradually to widen into richer harmonies reflecting broadening valley views] [Feature a brief horn passage evoking distant church towers across farmland] [Employ warm cello writing to provide an undertone of memory and passing years] [Create a modest central climax where piano and orchestra unite in expansive B-flat major chords] [Allow the music to subside quickly into a chamber-like dialogue between piano, oboe and solo violin] [Reintroduce the opening motif in a more mature and harmonically enriched form] [Conclude with high strings and piano harmonics fading into silence, as evening settles above the Deveron]
