104 results about "Musical composition" patented technology

Musical composition, music composition, or simply composition, can refer to an original piece or work of music , either vocal or instrumental, the structure of a musical piece, or to the process of creating or writing a new piece of music. People who create new compositions are called composers. Composers of primarily songs are usually called songwriters; with songs, the person who writes lyrics for a song is the lyricist. In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score," which is then performed by the composer or by other instrumental musicians or singers. In popular music and traditional music, songwriting may involve the creation of a basic outline of the song, called the lead sheet, which sets out the melody, lyrics and chord progression. In classical music, orchestration (choosing the instruments of a large music ensemble such as an orchestra which will play the different parts of music, such as the melody, accompaniment, countermelody, bassline and so on) is typically done by the composer, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a pop or traditional songwriter may not use written notation at all, and instead compose the song in their mind and then play, sing and/or record it from memory. In jazz and popular music, notable sound recordings by influential performers are given the weight that written or printed scores play in classical music.

Method and system for ai-based song remixing

According to an embodiment, a trained AI is provided that automatically identifies stems of a music work and loops within the stems. Information about the stems, the cut points of loops, and the loop's fundamental parameters will be formed into an AI Song pack. The remixing step uses the AI Song pack as a starting point and a database of loops is searched to identify audio loops that can replace loops with similar sonic characteristics in the music work to create a remix. Once some number of candidate loops have been identified a final remixed audio track will be produced which is comprised of replaced loops from the database. Alternatively, replacement stems might be created by replacing all loops in each stem. Finally, effects might be applied to the audio material created by either approach.

Artificial intelligence systems and methods for detecting musical infringement in symbolic music

The present disclosure relates to a system and method for detecting musical infringement in symbolic music. The system receives a first musical composition and, when provided as audio, converts it into a symbolic format using a transcription neural network trained to extract a main melody. It then generates k-mer sequences comprising consecutive notes, indexes these sequences in a data structure configured for dynamic conditioning, and compares them to reference musical compositions. Upon estimating a similarity measure that exceeds a threshold, the system performs a refined local sequence alignment adapted for music, accounting for key shifts, rests, and melodic or rhythmic variations. Based on this refined alignment, the system determines whether the first musical composition includes a musical fragment that infringes upon or regurgitates a portion of at least one reference composition.
