Centred on the remarkable reconstruction of Johan Niclas Cahman’s 1724 organ in the Kristine Church, Falun, this programme unfolds as both recital and sounding document. The instrument’s finely balanced “well-tempered” tuning, supple wind and eloquent voicing restore a tonal world poised between meantone warmth and emerging modern flexibility, lending distinctive character to each work. Sweelinck’s chorale variations and Buxtehude’s numerically wrought Passacaglia reveal the organ’s clarity of texture and rhythmic vitality. In Bach’s profound O Mensch, bewein’ dein’ Sünde groß, the singing line and expressive suspensions gain particular depth from the instrument’s speech and colour. Pachelbel’s partita and Italianate fantasia glow with chromatic nuance, while works by Krebs, Kauffmann and Kellner highlight dialogue between manuals and pedal, and, in selected pieces, the expressive interplay of oboe and organ. Mats Åberg shapes the programme with stylistic insight and architectural poise, allowing the reconstructed Cahman organ to speak with authority—at once luminous, grounded and vividly alive.
