Have your ever had a tune running through your head and not been able to remember what it was, who wrote it, or where you may have heard it?  When this happens to me, the tune seems to dig itself into my brain.  I can suppress the rogue engram by listening to other music I find compelling, but that’s not always convenient.  In many cases, the better alternative for mental housekeeping is to identify the tune and tuck it away into a larger memory.  But how does one identify a tune with no clues other than the tune itself? 

In seeking an answer to that question, I have discovered Musipedia, which is much more than a solution to my little conundrum.  Musipedia describes itself as “a searchable, editable, and expandable collection of tunes, melodies, and musical themes” that is being grown and maintained by a community of volunteers.  Musipedia lets you search for music in various ways.  If your computer has a working microphone, you can simply whistle or hum a part of what you’re looking for.  I was able to find the Tannhäuser Overture using this method.  A flash keyboard lets you listen while you peck out your tune, which worked for finding Yellow Submarine (by the Beatles) .  A JavaScript piano can be used to create a musical score, which allowed me to find Frère Jacques even with botched timing.  Another option, tapping the rhythm using any key on the computer (I used the spacebar), mostly didn’t work for me, though I was able to find Hark, the Herald Angels Sing by using the keyword “Christmas” in combination with tapping.  There’s also an option to use the mouse to create a musical grid, but I couldn’t get this to work for anything. 

Finally, you can enter a melodic contour using a Parsons code.  This is a simple notation that’s easy to learn and use. You start by entering the character * for the first note, then enter U if the next note goes up, D if it goes down, and R if it stays the same.  For example, the Parsons code for Amazing Grace is *UUDUDDDDRUUDUDUDUDUDDDUURDDRUUDUDD, which can be visualized as follows: 

Of course a tune will only be found if it’s in the Musipedia database, which is not comprehensive.  At present, the database seems to be most complete for classical music.  Another thing to keep in mind is that you don’t always know whether something that sounds like a repeated note (especially when there are sung lyrics) may be a held note in the score, and vice versa.  This can make it difficult to find a tune, even though you think you’ve reproduced it perfectly. 

If you can’t identify your tune with the tools Musipedia provides, you can try posting it in website’s the forum to see if another person can help you out.
