1. An information processing method implemented by a computer for a keyboard musical instrument provided with a pedal function for a pedal to extend sound production of a depressed key representing a pitch of a keyboard thereof, the information processing method comprising:
obtaining playing data representing a playing content that includes key data for operating the keyboard, but does not include any pedal data for operating the pedal; and
generating pedal operation data representing a pedal operation period of the pedal from the obtained playing data by a learned model, which is a statistical prediction model generated from machine learning using a plurality of sets of learning data, that has learned a relationship between an input corresponding to the playing data and an output corresponding to the pedal operation data,
wherein the playing data is musical instrument digital interface (MIDI) data compliant with a MIDI standard, and includes pitch operation data representing a sound production period for each of a plurality of pitches of the keyboard.
