Abstract: A method and system for rendering coded messages of any length is disclosed. The present invention includes writing a message, assigning alphanumeric characters and symbols to unique positions on piano keys aligned with Standard Music Notation (SMN) in accordance with a music scale or music mode. The aforementioned elements may be utilized with any or no time signature, and/or Morse code rhythms. The present invention may be applied to, combined, integrated, included with or within but not limited to: music, musical compositions, music performance, recordings, computer applications, film, virtual reality, and video games.

Abstract: The invention provides a method and apparatus for automatically generating a summary or key phrase for a song. The song, or a portion thereof, is digitized and converted into a sequence of feature vectors, such mel-frequency cepstral coefficients (MFCCs). The feature vectors are then processed in order decipher the song's structure. Those sections that correspond to different structural elements are then marked with corresponding labels. Once the song is labeled, various heuristics are applied to select a key phrase corresponding to the song's summary. For example, the system may identify the label that appears most frequently within the song, and then select the longest duration of that label as the summary.

Abstract: A musical score display device for a music score processor is formed into a rectangular platelike form so as to be detachably mounted on the processor. The device includes a cable for connecting the display device with the processor. The musical score display device may include an LCD provided with two touch sensors. By pressing the sensors, the next page or previous page of music score is displayed.

Abstract: An apparatus for inputting musical sheet data into a musical-sheet-printing system has a piano keyboard which has diatonic tone keys and chromatic tone keys and which generates first coded data, a function keyboard, a random access memory (RAM) for storing coded data supplied from these keyboards, a read-only memory for storing a permanent program and a conversion table representing a relationship between tonality values and chromatic tone pitches, and a control unit, under the control of the permanent program, for presetting a predetermined number of note data for the coded musical data, storing in the RAM the respective musical data included in the predetermined number of note data, accumulating the respective note data, calculating the respective entropy data in accordance with the accumulated musical data, selecting a tonality value having a maximum entropy, and determining an accidental and a note in accordance with the selected tonality value with reference to the conversion table.
