Hans Thomann Sr., a trumpet player, recognized that there was no
music store near Burgebrach, so he started selling wind instruments, eventually turning part of his family home into a music store in 1954. In 1968, a new wing was built on the home to house the store and its expansion into other product categories. In the 1980s, the company expanded into
mail order sales. In 2006, the company disclosed a turnover of EUR 129m, making it one of the fifty fastest-growing companies in Bavaria once more. In September 2010, Musikhaus Thomann received the Versender des Jahres (Mail Order Business of the Year) Award from the German Association of Mail Order Companies. The panel of judges chose Musikhaus Thomann for its strong growth, commitment to innovation, and high level of customer satisfaction. In 2011, Musikhaus Thomann was presented with the Global E-Commerce Award (Gold) at the Global E-Commerce Summit in
Barcelona. Eight national winners competed for the European prize. Thomann was the German nominee, having won the 2010 Mail Order Business of the Year Award. The jury noted that Thomann had demonstrated "the ability to tap into a market segment that a few years ago nobody believed could be served through internet retail" In 2022, Thomann GmbH achieved a turnover of around € 1.31 billion euros.
