An electronic musical instrument includes a display, a memory, and at least one processor. The memory is configured to store a plurality of song data items. Each of the plurality of song data items includes a plurality of event data items and the plurality of song data items does not include size information of each of the plurality of event data items. The at least one processor is configured to read at least one song data item from among the plurality of song data items, add an identifier to each of the plurality of event data items of the read at least one song data item, calculate size information for each of the plurality of event data items, associate the size information calculated for each of the plurality of event data items with the corresponding identifier, display a content of a first event data item, refer to the associated size information when the content of the first event data item is displayed on the display and a content of a second event data item is not displayed on the display, and display, in accordance with the associated size information referred to, the content of the second event data item on the display, instead of displaying the content of the first event data item.

The present disclosure relates to a method for generating a new chord sequence. The method comprises obtaining known chord sequences (S), wherein each known chord sequence has a respective known transition (T) between each pair of consecutive chords (C) in the known chord sequence. The method also comprises, among the chords of the known sequences, determining one or more new allowed transitions (N). The method also comprises, among the chords of the known chord sequences, generating a new chord sequence (L) based on there being a respective known or new allowed transition between each two consecutive chords in the new chord sequence, and the new chord sequence being loopable by there also being a known or new allowed transition between a first chord and a last chord in the new chord.

A handwriting numbered musical notation recognition system includes: a coding rules database; a music file database for storing a large numbers of music expression files which are collected and edited by computer used formats; a conversion unit for converting music expression files into numbered musical notation files; a handwriting database for storing relations between music symbols and handwriting trace data for numbered musical notations, and a handwriting combination unit connected to the handwriting trace database and the numbered musical notation coding sequences database; and a handwriting numbered musical notation recognition model used for recognition of the handwriting sequence. The music creation can be easily retained by electronic forms, while the creators still can create his (or her) music creations by handwriting. Furthermore, the recognition of the present invention supports the use of MusicXML formats, MIDI formats, or other computer formats.

Musical attribution is performed in a two-dimensional (2D) digital representation. A piece of music representing a musical score is inputted. An abstracted representation of blanks of the score, called a digital audio canvas, is produced. Interactive, dynamic attribution is performed by a user to bring to life the musical score of abstracted blanks. Instrumentation selection, relative volume, scale selection, and score tempo are all musical attributes that are conveyed to the score of abstracted blanks. The score of the digital audio canvas is played back using the attributed blanks. The playback of the score is enabled by selecting appropriate abstracted blanks. The appropriate abstracted blanks are included among other blanks for increased educational and enjoyment value. The modified score is converted back into the format of the original inputted piece of music.

The disclosure provides a digital keyboard instrument with seventeen keys per octave. Sharp and flat keys are split to produce additional microtonal notes on the upper end of each sharp or flat key while maintaining a traditional keyboard aesthetic. In some configurations, the digital keyboard instrument is configured to produce twenty two notes from the seventeen key octave. This digital keyboard instrument is configured to provide opportunities to musicians to perform a variety of microtonal music with a keyboard that provides ease of use with practical fingering placement.

According to embodiments of the present disclosure, systems, methods, and computer program products for audio- and video-editing are provided. A reference file comprising a visual representation (e.g., musical score) of a final video/audio product is read and displayed to a user. A plurality of sections (e.g., measures) and a plurality of symbols (e.g., notes) are determined. A plurality of audio/video recordings are read where each recording corresponding to at least a portion of the visual representation. For each of the plurality of sections, a corresponding segment of at least one of the plurality of audio/video recordings is determined. First selections of a section of the plurality of sections are received from the user. For each of the first selections, a listing of the plurality of audio/video recordings in which at least a portion of the selected section occurs is displayed to the user. For each of the first selections, a second selection of an audio/video recording from the listing is received from the user thereby linking the selected section to the corresponding segment of the selected audio/video recording. An audio/video file is generated by combining each of the linked segments.
