A media-content augmentation system includes a database with a multiplicity of media files and associated metadata. Each media file is mapped to at least one contextual theme defined by beginning and end timings. A processing system couples to the database; and an input couples to the processing system. The input is in the form of temporally-varying events data. The processing system resolves the input into one or more categorized contextual themes, correlates the themes with metadata associated with selected media files relevant to the themes, and then splices or fades together selected media files to reflect the events as the input varies with time, thus generating as an output, a media product in which transitions between media are aligned with the temporally-varying events. The database may contain sections of digital media files. A method aligns sections in digital media files with temporally-varying events data to compose a media product.

A system and methods for collaborating on a musical composition over a communication network, the system having processing circuitry that obtains the musical composition stored within a data storage device of the system, the musical composition including a first musical input data associated with a first channel, receives, via the communication network, second musical input data from a client device, the second musical input data being associated with a second channel, generates a data block based on the received second musical input data, the generated data block including synchronization data associated with the second musical input data relative to at least a portion of the musical composition, and transmits the data block to memory, the memory being accessible via the communication network to the client device and other client devices that are collaborating on the musical composition.

Systems, devices, and methods for encoding the harmonic structure of a musical composition in a digital data structure are described. Tonal and rhythmic commonalities are identified across the musical bars that make up a musical composition. Individual bars of the musical composition are each analyzed to characterize their respective harmonic fingerprints in various forms, and the respective harmonic fingerprints are compared to sort the musical bars into harmonic equivalence categories. Isomorphic mappings between hierarchical data structures that encode the musical composition based on musicality and harmony, respectively, are also described. The systems, devices, and methods for encoding the harmonic structure of a musical composition in a digital data structure have broad applicability in computer-based composition and variation of music.

Techniques described herein provide a computer implemented system, method and computer program for generating an audio output file, the method including steps of: selecting a subset of instrument content blocks from a group of instrument content blocks by determining a musical style for the audio output file, in which the musical style is configured with a plurality of musical slots and each slot is associated with a predetermined musical rule, using the predetermined musical rule for each slot to select a musical template from a plurality of musical templates for the slot, in which the selected musical template defines a chord progression of successive musical chords at a musical key and tempo, selecting for each slot an instrument content block that matches the chord progression defined by the selected musical template, and generating the audio output file by combining the subset of instrument content blocks. The method provides a configuration of musical slots each designated with musical rules that determine a musical template for the audio output file. Instrument content blocks that have a chord progression matching that defined by the template are selected for use together to provide an audio output file that is harmonically pleasing to listen to. User may configure the audio output file with an arrangement of tools.

Real-time jamming is automatically assisted for musicians. A real-time audio signal is received of played music that is played by at least one person. Beat is tracked of the played music from the real-time audio signal and accordingly a time of a next beat is predicted. At least one of chords; notes; and drum sounds is recognized from the real-time audio signal and repetitions in the played music are accordingly detected. A next development is predicted in the played music, based on the detected repetitions, including at least one of chords; notes; and drum sounds that will be played next, and respective timing based on the predicted time of the next beat. A real-time output is produced based on the predicted next development in the played music.

Systems and methods for re-arranging a musical composition using augmented reality are disclosed. A user can be provided with one or more physical image markers representative of at least one of a musical entity and a musical style in which a musical track has been pre-recorded. Upon capturing a visual scene in which one or more of these physical image markers are included, an augmented reality version of the visual scene is displayed along with audio corresponding to the musical style(s) and/or entities represented by the one or more physical image markers.

A toy musical instrument having a compact housing supporting an automated music composition and generation engine that is driven by icon-based musical experience descriptors and musical style descriptors, selected by a child or adult during a video scoring process.

Systems and processes that use MIDI mapping technology for multiple chord and arpeggio triggering are disclosed, including a multiple chord and arpeggio triggering MIDI mapping system and process that assigns, selects, and records chord and multi-arpeggio functions into a digital audio workstation (DAW) host program or an internalized sequencer and a two-phase multiple chord and time-delayed arpeggio triggering MIDI mapping process for recording a chord progression and enabling multi-arpeggio functions of the chords in the chord progression to be worked on at any time-delayed instance after recording the chord progression. The system divides output from a MIDI controller into chord generators and arpeggiators to allow users to define full chords with a single key selection, while also making immediate or time-delayed single key selections for different arpeggios.

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.

There is provided an audio device for playing a music piece, the music piece including a first part and a second part that are acoustically separable from each other, the audio device including: a first playing module configured to play the first part; and a second playing module configured to play, in parallel with playing of the first part, the second part in a first temporal pattern in a first segment of the music piece, and at least one sound included in the second part at a position that is different from a position in the first temporal pattern in a second segment of the music piece.
