Device for deciphering a score and teaching aid for learning and practising the playing of a poliphonic musical instrument

摘要

The score decoder and learning aid includes two plane elements (1,2). The first of these elements is in the form of a plate shaped casing. This element has several windows in one or more of its faces. The windows are associated with pictures representing positions of fingers during playing of an instrument. The second plane element slides relative to the first. It has pictures corresponding to positions of fingers for forming either a chord or single note. Pictures generated using the two elements are combined. Labels (4) can be temporarily attached to sheets of music.
