Everyday, I see it working with bands; At some point someone says a part sounds too much like another song. This is where your iPhone comes in! There is an App, that is very popular called Shazam, where you can hum, sing or play a song and it will tell you which song it is! Most people use this out at the bars, clubs or cars to figure out what a DJ is playing. However, the really amazing use of this is to be able to see if your melody is too close to another songs melody! If Shazam sees your song as being the same as another popular one, you may need to go back to the drawing board. Of course it could also tell you, you sound like a song you think you are going to be way better than. In that case, carry on!
We stand corrected, Chris from Shazam has written in to tell us this is not possible with their App. However it is with Midomi, so head here for a corrected article.
