Gilberto Guarino plays Buxtehude's Choralbearbeitungen: "Ach Herr, mich armen Sünder" ("O Haupt voll Blut un Wunden"), BuxWV 178.
Temperament: Werckmeister III/A=454.
This highly refined chorale has a chamber music nature. It is actually Buxtehude's elaboration of chorale tune "Herzlich tut mich verlangen". In the city of Lübeck it was played as a Penitence chorale (ap. Kerala Snyder - "Dieterich Buxtehude - Organist in Lübeck", p. 496. Revised Edition "University of Rochester Press").
