A processor-based method of producing a generative musical composition is disclosed herein. The method includes the step of receiving a briefing narrative which describes a musical journey by referencing a plurality of emotional descriptions related to a plurality of musical sections. The generative musical composition is assembled with regard to the briefing narrative through the selection and concatenation of Form Atoms with tags that align with the emotional descriptions related to the musical sections. The Form Atoms, which have compositional nature aligned with the emotional descriptions and self-contained constructional properties representative of the historical corpus of music, are then selected and substituted into the generative composition. The method further involves the step of generating the musical composition by mapping musical transition between selectively chosen Form Atoms to reflect pre-established transitions between Form Atoms and groups Form Atoms that have been identified to have similar tags but different constructional properties.

In examples, a method for converting audio samples to full song arrangements is provided. The method includes receiving audio sample data, determining a melodic transcription, based on the audio sample data, and determining a sequence of music chords, based on the melodic transcription. The method further includes generating a full song arrangement, based on the sequence of music chords, and the audio sample data.

An electronic musical instrument includes: a chord-playing input device; a sounding part that emits chord sounds; and a display part that displays an image. The chord-playing input device includes: a chord designating button group assigned with chords; a chord changing button group assigned with change methods for changing an assignment state for the chord designating button group; a sounding information generating part that generates sounding information for making the sounding part emit the sound of the chord corresponding to operation for the chord designating button group and chord changing button group; and a display information generating part that generates display information for making the display part display a plurality of chord images and change method images in the same arrangement order as those of the chord designating button group and chord changing button group.

Systems and methods are disclosed for generating color sets based on musical concepts of pitch intervals and harmony. Color sets are derived via a music-to-hue process which analyzes musical pitch data associated with musical input to determine pitch intervals included in the music. Pitch interval angles associated with the pitch intervals are applied to a tuned hue index to identify hue note ordered within the index which are separated by a hue interval angle similar to the pitch angle associated with the analyzed pitch data. The systems and methods provide for the creation of color sets which are analogous to musical chords in that they include multiple hue notes selected based on hue interval angles derived from musical interval angles associated with the received musical input.

Coordinated audio and video filter pairs are applied to enhance artistic and emotional content of audiovisual performances. Such filter pairs, when applied in audio and video processing pipelines of an audiovisual application hosted on a portable computing device (such as a mobile phone or media player, a computing pad or tablet, a game controller or a personal digital assistant or book reader) can allow user selection of effects that enhance both audio and video coordinated therewith. Coordinated audio and video are captured, filtered and rendered at the portable computing device using camera and microphone interfaces, using digital signal processing software executable on a processor and using storage, speaker and display devices of, or interoperable with, the device. By providing audiovisual capture and personalization on an intimate handheld device, social interactions and postings of a type made popular by modern social networking platforms can now be extended to audiovisual content.

An information processing system acquires a detection signal corresponding to each manipulated operator, among the plurality of operators, that has been manipulated by a user and identifies a manipulation amount or intensity of each of the plurality of operators based on the acquired detection signal. The system further identifies a chord that corresponds, from among the plurality of operators, to a combination of detected two or more manipulated operators. The identifying of the chord includes determining a root note pitch included in the chord based on the manipulation amount or intensity of each of the detected two or more manipulated operators.

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.
