In contrast to the German design, the Schrammel harmonica has a closed construction, which is known as the Viennese construction. The mechanism was moved into the case.

The Schrammel harmonica was named after the style-defining quartet of the brothers Johann and Josef Schrammel, in which it was used. This type of harmonica, first documented around 1870, with a logical and unisonoric melody side became the forerunner for all of today's unisonoric accordions.
