PROBLEM TO BE SOLVED: To provide a system and a method for retrieving music by which impression data converted from feature data can be changed into the data matched with user's taste by means of a hierarchical neural network. SOLUTION: After impression data displayed in a correction data input area is corrected and input by a PC operation part 19, a correction execution button is clicked. By clicking the correction execution button, the corrected impression data is input as correction data to a music retrieval part 18. The music retrieval part 18 updates impression data stored in a music database 15 to the input correction data, reads feature data from the music database 15, and stores the correction data and the feature data as relearning data in a correction data storage part 23.
