This disclosure discloses various computing technologies that enable a user to insert a personal vocal content into an original song in a quick and simple manner, thereby potentially creating a derivative work of the original song. Additionally, these technologies enable a right holder of the original song to monitor the new derivative work in a granular, reliable, de-centralized, and secure manner.

A method and apparatus for music generation may include steps of receiving any length of input; recognizing pitches and rhythm of the input; generating a first segment of a full music; generating segments other than the first segment to complete the full music; generating connecting notes, chords and beats of the segments of the full music and handling anacrusis; and generating instrument accompaniment for the full music, and comprise a music generating system to realize the steps of music generation.

A system and method for estimating the popularity of song by calculating the (absolute and/or contrastive) harmonic surprise of each song in a corpus of music data, determining the popularity of each song in the corpus (e.g., based on a music chart, downloads, online streams), determining correlations between harmonic surprise and popularity, and estimating the popularity of an individual song based on the (absolute and/or contrastive) harmonic surprise of the individual song and the correlations between harmonic surprise and popularity.

An apparatus, method, and computer-readable storage medium that generate a harmonized musical piece. The method includes receiving a chord selection including a musical key and a scale selection, generating, within a digital audio work session, a chord progression sequence based on the received chord selection, in response to a detected chord selection change, modifying the chord progression sequence to include a chord progression corresponding to the chord selection change, setting the chord progression sequence as a master sequence, in response to detecting a second progression sequence within the digital audio work session, transmitting an identifier to the second progression sequence setting it as a slave sequence, and establishing a synchronized communication link between the master and the slave sequences such that changes made in the master sequence are automatically effectuated in the slave sequence, and combining the master sequence and the slave sequence to form a composed musical piece.

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.

The present invention provides method and system for composing music with chord accompaniment. One or more keys on a first keyboard are selected by end-users to generate a chord progression, and a computer generates a chord progression MIDI file, and associates the file with a first physical card that is embedded with a unique machine-readable ID (UID). After the UID of the first physical card is subsequently recognized, the chord progression MIDI file is retrieved and played. While the chord progression MIDI file is played, certain keys on a second keyboard are highlighted, and each of the highlighted keys on a second keyboard represents a music note that is in harmony with a particular chord in the chord progression while the particular chord is being played, and one or more of the highlighted keys on the second keyboard are selected by the end-user to compose a melody.

A music generation system is provided comprising a processor and a memory operatively coupled to the processor and storing a rhythm template database comprising a plurality of rhythm templates, and a music generation program stored in the memory and executed by the processor to be configured to receive a user input of lyrics, identify a plurality of syllables in the lyrics, determine a syllable pattern in the identified plurality of syllables, match the syllable pattern to a selected rhythm template of the plurality of rhythm templates, generate a melody based on the selected rhythm template, generate a music file encoding the melody and the lyrics, and output the music file encoding the melody and the lyrics.

A method for automatically generating an audio signal, the method comprising receiving a source audio signal analyzing the source audio signal to identify a musical parameter characteristic thereof obtaining a supplemental audio signal based on the identified musical parameter characteristic and combining the source audio signal and the supplemental audio signal to form an extended audio signal.

A data conversion system includes an acquisition unit, a conversion unit, and an output unit. The acquisition unit acquires first data. The conversion unit converts the first data into second data based on a conversion parameter to be determined by reference data related to a subject. The output unit outputs the second data.
