Abstract
Abstract A composition or a series of notes to be transposed are introduced with mathematical data into the memory (11) of a computer (1). A calculator (12) works out the data and a control unit (13) actuates an optical (4) or acoustical (3) output device. All the series of notes received and calculated may be addressed by the computer to a memory (5) external to the computer.
