“Query by Humming” may be coming soon to a search engine near you. The Fraunhofer Institut in Germany created the MP3 audio format and now they have a solution to “name that tune.” It matches pitch differences to a database of songs. Other companies are creating similar software. Wouldn’t if have been neat to hum a tune into Napster and have it fetch matching mp3s for you? Composers could check to see if they are unintentionally plagiarizing.
