This is fun to play around with:
It recognized the Mozart tunes I tapped.
Well, I tried 2 Mozart Sonatas and 2 folk tunes (Arkansas Traveller and Turkey in the Straw). All not recognized.
I got The Marriage of Figaro, A Little Night Music, and Alla Turca successfully... the less popular ones are not part of the database I guess. I also got Music of the Night and Angel of Music successfully, but Masquerade was a no show...
Tried Eine Kline Nacht Musik and the beginning of Mozart Symphony No. 40. Both recognized!
It is very interesting to find other tunes similar to one you tapped.
