Abstract

The electronic apparatus comprises a processing unit for classification and storage of a plurality of musical compositions, and a control device, such as a keyboard or MIDI connection, for performing of sequences of connoting musical events, to be stored and related to each single musical composition. The same control device may then be, used for performing of one or more sequences of searching musical events, in order to automatically find and subsequently read-out an associated musical composition from a storage memory of the CPU. For this purpose, the processing unit comprises program means for comparing a searching sequence with the connoting sequence of musical events, reading-out one or more of the stored musical compositions in the event of total or partial equivalence between the compared sequences of musical events. It is thus possible to search for and identify a specific musical composition in short periods of time from a plurality of stored musical compositions, by using a simple musical technique.
