摘要： A musical composition is varied using a computational model of rubato. Rubato is modeled by changes to the symbolic onset and/or symbolic offset of each note, which allows for a greater flexibility in timing modifications, such as asymptotic tempo and localized retrogrades. A user selects notes to be modified (e.g., by plotting points to modify notes over a selected interval), and a curve fitting (e.g., a cubic spline interpolation) is used to determine modifications for other notes in the composition. These symbolic onset/offset modifications may also be translated into tempo modifications. The symbolic onset and/or offset modifications are applied to the composition to produce an adjusted musical composition, to which rubato has been applied. Rubato profiles can similarly be extracted from existing musical recordings and used to characterize the recordings, such as for training machine learning models and recommender systems.
