ORPHEUS (On-line Retrieval from Polyhymnia: the Human-oriented Experimental
Utrecht Searcher)
The objective of the Orpheus project is to approach the following three
fundamental issues in music retrieval:
- Matching. Given a query theme or melody, determine if it is contained in
collection of (possibly longer) melodies or complete works.
- Polyphonic matching. Given a query melody, determine is it is contained in
a polyphonic piece of music.
- Indexing. Given a large collection of music, build a data structure to
efficiently search for those pieces similar to the query.
