Music may be generated by electronically applying one or more functions that change a compositional nature of a musical input in a first tonality to generate a musical output in a second tonality in response to an event in a videogame. Data corresponding to the output melody may be recorded in a recording medium.

A generative composition system reduces existing musical artefacts to constituent elements termed “Form Atoms”. These Form Atoms may each be of varying length and have musical properties and associations that link together through Markov chains. To provide myriad new composition, a set of heuristics ensures that musical textures between concatenated musical sections follow a supplied and defined briefing narrative for the new composition whilst contiguous concatenated Form Atoms are also automatically selected to see that similarities in respective and identified attributes of musical textures for those musical sections are maintained to support maintenance of musical form. Independent aspects of the disclosure further ensure that, within the composition work, such as a media product or a real-time audio stream, chord spacing determination and control are practiced to maintain musical sense in the new composition. Further, a structuring of primitive heuristics operates to maintain pitch and permit key transformation. The system and its functionality provides signal analysis and music generation through allowing emotional connotations to be specified and reproduced from cross-referenced Form-Atoms.

Systems and methods are provided for using a common “vocabulary,” predefined or dynamically generated based on user-provided content, to transform biometric and/or neurometric data collected from one or more people into a coherent audio and/or visual result. One method comprises receiving a first incoming signal from a bio-generated data sensing device worn by a first user; determining a first set of output values based on the first incoming signal, a common vocabulary comprising a list of possible output values, and a parameter file comprising a set of instructions for applying the common vocabulary to the first incoming signal to derive the first set of output values; generating a first output array comprising the first set of output values; and providing the first output array to an output delivery system configured to render the first output array as a first audio and/or visual output.

A method for processing a voice signal by an electronic system to create a song is disclosed. The method comprises the steps in the electronic system of acquiring an input singing voice recording (11); estimating a musical key (15b) and a Tempo (15a) from the singing voice recording (11); defining a tuning control (16) and a timing control (17) able to align the singing voice recording (11) with the estimated musical key (15b) and Tempo (15a); applying the tuning control (16) and the timing control (17) to the singing voice recording (11) so that an aligned voice recording (20) is obtained. Next, the method comprises the step of generating an music accompaniment (23) as function of the estimated musical key (15b) and Tempo (15a) and an arrangement database (22) and mixing the aligned voice recording (20) and the music accompaniment (23) to obtain the song (12). A system a server and a device are also disclosed.

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.

An audio signal generation device (20) includes: an acquirer (210) configured to acquire biological information of a human subject; an audio signal generator (245) configured to generate an audio signal based on at least one of a plurality of pieces of sound information; and a switching cycle decider (241) configured to decide a switching cycle, such that first sound information switches to second sound information at a cycle that is in accordance with the biological information, the first sound information and the second sound information being included in the plurality of sound information pieces, and the audio signal generator (245) generates an audio signal based on the second sound information, at the switching cycle decided by the switching cycle decider (241).

Provided is an electrophonic chordophone system (20) comprising sensor (24) configured to be operatively responsive to respective strings of a guitar (22). The system (20) also includes non-transitory processor-readable storage means (26) which contains first and second user-configurable tonal formats (28) and (30). Also included is processor (32), arranged in signal communication with the sensor (24) and storage means (26), and adapted to associate a melody group of notes producible by the strings with the first tonal format (28) in a one-to-one mapping or direct correlation, and to associate a control group of notes producible by the strings with the second tonal format (30) in a one-to-many mapping or indirect correlation. Also included is a synthesiser (34), arranged in signal communication with the processor (32), and configured to produce both the first and second tonal formats simultaneously in substantial real-time. The first tonal format (28) is actuatable via the melody group of notes and the second tonal format (30) is dynamically selectable via the control group of notes and also actuatable via the melody group of notes. In this manner, a melody is producible via the first tonal format (28) with a dynamic backing track producible via the second tonal format (30), all using one guitar (22).
