Polyphonic Score Retrieval Using Polyphonic Audio Queries: A Harmonic Modeling Approach

Jeremy Pickens, Juan Pablo Bello, Giuliano Monti, Mark Sandler, Tim Crawford, Matthew Dovey, Don Byrd
2003 Journal of New Music Research  
To our knowledge, we are the first to use polyphonic audio queries to retrieve from polyphonic symbolic collections.  ...  As humming in multiple voices is quite difficult, the task is more accurately described as "query by audio example," onto a collection of scores.  ...  We would also like to thank Naxos for the use of their Bach Prelude and Fugue audio recordings.  ...

Polyphonic music retrieval

Shyamala Doraisamy
2005 SIGIR Forum  
For this, ratios of onset times between two adjacent pairs of pitch events are used.  ...  To encode 'musical n-grams' to obtain 'musical words' for indexing, a function that maps interval classes to text characters is formulated, and ranges of ratio bins are defined.  ...  Class sizes require further investigation to determine their usefulness in providing allowances for more fault-tolerant retrieval.  ...
