Audio thumbnail generation of Irish traditional music

An approach is presented which generates an audio thumbnail of Irish Traditional music. An audio thumbnail is considered to be the most representative segment of the music. For popular music, the chorus is considered to be an ideal audio thumbnail, however in Irish Traditional music there is no chorus. An Irish Traditional tune consists of two or more short structural segments called parts. Parts are repeated to extend the tune, and the tune itself is also repeated once or more in its entirety. To further extend a performance, tunes are concatenated to form a set of tunes. As a result, there is plenty of repetition within this music type. The presented approach utilises an existing approach which calculates the structure of Irish Traditional Music. The structural information is used to extract a single rendition of each distinctive part. The resulting parts are concatenated to form the audio thumbnail.
