An artificial intelligence system includes: one memory configured to store instructions; and one processor configured to execute the instructions to encode music data to generate input tokens from input digital music protocol data and store the input tokens in the one memory; access a data structure in the one memory to load the input tokens; generate one data representation by concatenating a token embedding result converted from the loaded input tokens and a structural embedding result comprising one of a part embedding, a type embedding, a time embedding, and a pitch class embedding; ingest the data representation into at least one artificial intelligence model executed by the one processor; infer, by the one artificial intelligence model, a next output token based on the data representation to generate symbolic music data; and manifest the generated symbolic music data through a user interface.
