A real-time music generation engine for an interactive system includes a Musical Rule Set (MRS AND/OR CA AND/OR PCU) unit configured to combine predefined composer input with a real-time control signal into a music signal; a Constructor Automaton (CA) configured to generate a fluid piece of music based on rule definitions defined by the predefined composer input within the MRS AND/OR CA AND/OR PCU unit by musical handlers; and a Performance Cluster Unit (PCU) configured to convert the fluid piece of music from the CA into a corresponding music control signal for real-time playback by the interactive system.

Systems and methods for versioning audio elements used in generation of music are provided. An example method includes receiving musical format data associated with a plurality of audio elements of a melody; determining, based on the musical format data, harmonic and melodic characteristics of each of the plurality of audio elements; matching the harmonic and melodic characteristics to a plurality of chord progressions using predetermined music theory rules, counterpoint rules, and rhythm matching rules; deriving, based on the matching and predetermined melodic movement rules, from the plurality of chord progressions, melodic movement characteristics applicable to using in versioning; and creating, based on the predetermined music theory rules and the melodic movement characteristics, versions of the audio elements that match the chord progressions.

A social entertainment user interface operating on a wireless networked record session device capable of producing a live video and/or audio stream as if made in a vintage record booth. Record sessions are listened to and/or watched by a plurality of other social entertainment user interfaces operating on other networked listening/watching wireless networked devices. Video and audio filters emulate various altered looks and sounds. Record sessions are streamed live or near-live for other social entertainment user interfaces operating on other networked wireless devices to listen and/or watch, and passively and actively rated to dynamically enable watching of the most preferred record sessions.

Techniques are disclosed relating to determining composition rules, based on existing music content, to automatically generate new music content. In some embodiments, a computer system accesses a set of music content and generates a set of composition rules based on analyzing combinations of multiple loops in the set of music content. In some embodiments, the system generates new music content by selecting loops from a set of loops and combining selected ones of the loops such that multiple ones of the loops overlap in time. In some embodiments, the selecting and combining loops is performed based on the set of composition rules and attributes of loops in the set of loops.

A system and method to identify a digital representation of a first musical composition including a set of musical blocks. A set of parameters associated with video content are identified. In accordance with one or more rules, one or more of the set of musical blocks of the first musical composition are modified based on the set of parameters to generate a derivative musical composition corresponding to the video content. An audio file including the derivative musical composition corresponding to the video content is generated.

A virtual instrument for real-time musical generation includes a musical rule set unit for defining musical rules, a time constrained pitch generator for synchronizing generated music, an audio generator for generating audio signals, wherein the rule definitions describe real-time morphable music parameters, and said morphable music parameters are controllable directly by the real-time control signal. With this virtual instrument, the user can create new musical content in a simple and interactive way regardless of the level of musical training obtained before using the instrument.

Methods, systems, and apparatus, including medium-encoded computer program products, for receiving outputs from a plurality of models that are each informed by real-time data provided by one or more sensors that are present in an aquaculture environment. An input is generated for an algorithmic music composer for algorithmically composing music that reflects multiple current conditions within the aquaculture environment, based at least on the received outputs from the plurality of models. The input is provided to the algorithmic music composer to algorithmically compose the music that reflects the multiple current conditions within the aquaculture environment.

An adaptive music playback system is disclosed. The system includes a composition system that receives information corresponding to user activity levels. The composition system modifies the composition of a song in response to changes in user activity. The modifications are made according to a set of composition rules to facilitate smooth musical transitions.
