This invention belongs to the field of music data processing and relates to a symbolic music classification method and system based on Tonnetz spatiotemporal graphs. The method generates a two-dimensional grid of symbolic music data, consisting of time frames and pitches, and defines graph nodes and initial features for each grid point. Discrete note events are organized into structured nodes. Based on this two-dimensional grid, graph nodes corresponding to pitches that satisfy Tonnetz interval relationships are connected within the same time frame to form spatial edges. These spatial edges explicitly introduce consonant interval relationships between pitches, allowing the model to directly obtain structural information with musicological significance without relying on large amounts of data for self-learning, thus solving the problem of insufficient utilization of harmonic structure. Furthermore, graph nodes with the same pitch or pitch differences within a preset range are connected between adjacent time frames to form temporal edges. These temporal edges directly encode the continuous and stepwise motion of unison parts during voice progression, enabling the model to capture the dynamic evolution of music in the time dimension and solving the problem of missing voice progression characterization.
