A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

Techniques for generating a virtual music experience. The techniques include source separating an arbitrary digital audio input into a plurality of source-separated tracks. Sets of music features are determined from the plurality of source-separated tracks and provided to a video presentation system at a video frame rate of the video presentation system. The providing the sets of music features to the video presentation system causes the video presentation system to animate one or more graphical assets based on the provided sets of music features.

An automatic performance system includes a sign detector configured to detect a sign action of a performer performing a musical piece, a performance analyzer configured to sequentially estimates a performance position in the musical piece by analyzing an acoustic signal representing performed sound in parallel with the performance, and a performance controller configured to control an automatic performance device to carry out an automatic performance of the musical piece so that the automatic performance is synchronized with the sign action detected by the sign detector and a progress of the performance position estimated by the performance analyzer.

An apparatus configured to, based on a location of a plurality of distinct audio sources in virtual reality content captured of a scene, a first virtual reality view providing a view of the scene from a first point of view, wherein at least two of said audio sources are one or more of: a) within a first predetermined angular separation of one another in the first virtual reality view, b) positioned in the scene such that not all are within the field of view, provide for display of a second virtual reality view from second point of view satisfying a predetermined criterion, the predetermined criterion comprising a point of view from which said audio sources are separated by at least a second predetermined angular separation and are within a field of view of the second virtual reality view to provide for control of audio properties of said audio sources.

A musical instrument performance solution is described. Labels with visual indicators provide a reference to performers such that a proper combination of instrument inputs may be selected at the appropriate time. The visual indicators include colors and/or shapes. The visual indicators may be presented using differently-colored lyrical text, where each color corresponds to a set of notes. Each set of notes may for a chordal group such as a triad. The visual indicators may be associated with labels that are able to be adhered to various instrument inputs such as keys of a keyboard or piano.

A method for dynamic modification of audio content. An audio content theme includes audio information relating to at least one theme variation. The method includes the steps of: receiving an intensity parameter indicative of an amount of audio information being played and a variation parameter indicative of at least one theme variation of the audio information being played; modifying, based on said intensity parameter, the amount of audio information being played, and, based on said variation parameter, the at least one theme variation of the audio information being played. Also described is a computer program configured to be executed on a computer device for dynamic modification of an audio content theme.

Devices and methods for improving the field of signal generation are provided by transforming computer images into signals. In some embodiments the invention relates to computer music synthesis applications. Other applications include but are not limited to, speech, text, numerical, digital or analogue signals, and other signals that can be generated from images. Some embodiments include an electronic display or displays, and one or more input devices, processors and output devices.

An apparatus, method, and computer-readable storage medium that generate a harmonized musical piece. The method includes receiving a chord selection including a musical key and a scale selection, generating, within a digital audio work session, a chord progression sequence based on the received chord selection, in response to a detected chord selection change, modifying the chord progression sequence to include a chord progression corresponding to the chord selection change, setting the chord progression sequence as a master sequence, in response to detecting a second progression sequence within the digital audio work session, transmitting an identifier to the second progression sequence setting it as a slave sequence, and establishing a synchronized communication link between the master and the slave sequences such that changes made in the master sequence are automatically effectuated in the slave sequence, and combining the master sequence and the slave sequence to form a composed musical piece.
