Effective use of multimedia collections requires efficient and intuitive methods of searching and browsing. This work considers databases which store music and explores how these may best be searched by providing input queries in some musical form. For the average person, humming several notes of the desired melody is the most straightforward method for providing this input, but such input is very likely to contain several errors. Previously proposed implementations of so-called

We conducted experiments which revealed that the expected error rate for user queries is much higher than existing algorithms can tolerate. We then developed algorithms based on approximate matching techniques which deliver much improved results when comparing error-filled vocal user queries against a music collection.
