PROBLEM TO BE SOLVED: To provide a new musical instrument sound recognition method which is not dependent on sound output time and F0 estimation processing. SOLUTION: The musical instrument sound recognition method comprises the steps of: calculating an unspecified musical instrument existence probability; calculating a conditional musical instrument existence probability; and calculating a product of both probabilities. In the musical instrument sound recognition method, recognition accuracy is higher than a conventional method, since the musical existence probability is calculated without performing musical sound recognition for each single tone. Moreover, it is easy to visualize it as Instrogram on a time t - frequency f plane, and by using this, various applications can be considered, such as, performing musical instrument annotation and performing similar music searching based on a music piece structure.
