Abstract: 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.

Abstract: Techniques are described for generating music data for accompaniment using machine learning (ML) techniques. In an implementation, MIDI-formatted music data is tokenized as a music token sequence. Based on the input music token sequence of a portion of an original music signal, a trained ML model generates an output music token sequence for a portion of a generated music signal. Such a portion of the generated music signal is temporally ahead of the portion of the original music signal, which was used to generate the portion of the generated music signal.

Abstract: A method and system for visualizing music using a perceptually conformal mapping system are provided. A music source file is input into a processor configured to carry out a series of steps on audio cues identified within the music and ultimately generate a simultaneous visual representation on a display device. The series of steps include application of one or more perceptually conformal mapping systems that essentially induce a synesthetic experience in which a person can experience music both acoustically and visually at the same time. The device extracts cues from the music that are designed to specifically capture fundamentals of human appreciation, maps them into visual cues, then presents those visual cues synchronized with the source music.

Abstract: Computer-based systems, devices, and methods for automatically generating aesthetic chord progressions and key modulations in musical compositions are described. Known harmonic relationships are expanded upon to produce a much richer set of harmonic transition probability models compared to conventional music theory, and these models are leveraged by a computer-based musical composition system to generate new musical compositions and variations of existing musical compositions. Techniques for enabling a computer-based musical composition system to automatically determine when to introduce a key modulation, what key to module to, and what chord progression(s) to use within the new key are all described.

Abstract: Techniques are disclosed herein for generating harmonious audio. An input for changing a mode of an electronic device from a first mode to a second mode can be received and, in response, a controller of the electronic device can modify electrical connections between a matrix circuit and a set of keys of the electronic device. In modifying the electrical connections, a set of tones associated with a first subset of keys of the set of keys can be associated with a second subset of keys of the set of keys. Keys of the second subset of keys can be adjacent to at least one other key of the second subset of keys and tones of the set of tones can be associated with respective keys of the second subset of keys. Audio output when one key is operated can be harmonious with audio output when other keys are operated.
