  • Natural Finishes, Old Soundboards, and Rebuilding Steinways with Oliver Greinus
    May 24 2026

    In this episode, we sit down with former Hamburg Steinway technician and soundboard extraordinaire Oliver Greinus. Oliver is one of the co-founders of Klangmanufaktur, a workshop that specializes in rebuilding Steinways as well as providing rehearsal space and practice rooms for Hamburg's musical community. Following our tour of the workshop, Oliver sat down with me to talk about their reasoning for leaving Steinway in order to create their own uniquely rebuilt instruments; why old soundboards should never be replaced; doing away with polyester in favor of natural oil finishes; replacing lead weights with CKM brass; their rental program for connecting musicians and institutions with quality pianos; and the curriculum for their singular week-long training seminar.
