The free multi-media catalog app "MKG Musical Instruments" presents 100 highlights of the world-famous collection of the Museum of Arts and Crafts. All instruments are shown in high-resolution photos. The instruments are described and the historical development of individual instrument types as well as the cultural-historical context are presented. In over 50 film clips, which were produced with students and graduates of the University of Music and Theater Hamburg, a large part of the instruments can also be experienced musically. Many of the collection pieces are documented here for the first time in music films, including historically unique objects such as the keyboard instruments of the collection Prof. Dr. med. Andreas Beurmann, a seven-string viola da gamba and a Hamburg Cithrinchen by Joachim Tielke and the famous dual-manual harpsichord by Christian Zell.
