Abstract: In an embodiment, a text providing method includes providing chord input data, in which chords are aligned in chronological order, to a trained model in which a relationship between chord sequence data, in which chords are aligned in chronological order, and explanatory text related to the chords included in the chord sequence data is learned, and obtaining text corresponding to the chord input data from the trained model.

Abstract: A computer-implemented sound processing method includes: outputting singing sound data based on a sound signal representing singing sound; and outputting sound data representing musical instrument sound that correlates with musical elements of the singing sound, by inputting input data that includes the singing sound data to a trained model that has learned, by machine learning, a relationship between singing sound for training and musical instrument sound for training.
