Born from Willy Wolf’s 1964 invention in an Amsterdam home, Wolf Music Products b.v. makes shoulder rests and related accessories for violinists and violists. The company developed its Forte shoulder rests in a Utrecht backyard shed and is now run by Willy’s son Robert and his wife Simone, who introduced sparkling, three-dimensional colored shoulder rests alongside newer production methods. Its products are latex-free, with a broad range of adjustable models designed to accommodate individual players.
