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).

A method and system for analyzing patterns in the relationships of notes of an input piece of music. The method comprises generating a set of the most frequently occurring note pitches in ascending pitch order that matches an interval pattern, and detecting out-of-key pitches that lie outside of this interval pattern. One or more potential key sequence bifurcations are identified which represent a list of possible key sequences according to forwards and backwards analysis. By finding patterns of repetition in the chordal sequences that may be generated according to these key sequence bifurcations, a key sequence that allows the most frequently recurring chord sequences may be chosen. Chord sequences may be analyzed by using ghost chords, temporary harmonic structures that are created, updated and finalized over time according to a combination of essential and inessential note fragments. The method further comprises identifying non-harmony pitches according to the analyzed chord sequence.

The present disclosure provides systems and methods by which music can be created and played by automatically defining a set of pitches that can be selected based on interval changes for pitch values within the set. A set of available pitches within a particular series can be referred to as a pitch palette, wherein each available pitch within the pitch palette is associated with being some predefined interval from any other pitch within the pitch palette. In accordance with aspects of the disclosure, a device may be configured to automatically identify particular pitch palettes that correspond with certain pitches or with particular pieces of music.

A Form Atom defined by self-contained constructional properties representing a historical corpus of music and contained within metadata of the Form Atom is disclosed. The Form Atom has a generative set of heuristics to support generation of a set of chords in a chord scheme or many different sets of chords. The generated chords are spaced out within a defined window of musical time by chord spacer heuristics. The Form Atom has a tag describing its compositional heuristics. A chord list of the Form Atom is provided in local tonic and defines branching structures that may be used for the generation of different chords from the local tonic. A progression descriptor is combined with a form function such that the Form Atom expresses musically a question, an answer and a statement. A meta-map of a chord scheme for a musical section is created from the metadata.

A computer implemented method for encrypting and decrypting a graphic or message as musical notes. The method includes generating a composition key, selecting a graphic or message to be encrypted, identifying a color associated with each pixel within the graphic or message, ranking each color by order of its prevalence within the graphic or message, assigning a note to each color in a music tool as determined by the composition key, and saving the notes to a file.

A system for audibly conveying financial information using a computerized system. The system receives financial information includes a variable parameter which varies over a time period. The at least one processor associates the received financial data with a musical instrument. It also determines, for a plurality of values of the variable parameter during a time period, a plurality of musical notes based on the values of the variable parameter, and generates audio data associated with the plurality of musical notes corresponding to the changes in the variable parameter. When the processor determines whether any of the plurality of generated musical notes for the associated musical instrument are at the highest or lowest range, and automatically readjust the tonal range of the musical notes or changes the associated musical instrument. The system-generated audio data is audibly reproduced in musical notes of the associated musical instrument.
