A humdinger harmonica

Since it can play seven notes in C-major, the world's Smallest Harmonica is actually a useful melody maker. Before you even ask, yes, you can play the main riff to "Piano Man" by Billy Joel. Frankly, being able to bust out that riff anywhere you go is worth every penny (which is about 2/3 the length of this little beauty).

Here are a few other ditties you can play on this little gem: "Jingle Bells", "Twinkle, Twinkle Little Star" (aka the Alphabet Song), "Mary Had a Little Lamb", "Hot Cross Buns" (from piano class, remember?), the Batman theme song, the Superman theme song, the Jeopardy! theme song, "Low Rider", "Spring" from the Four Seasons by Vivaldi (to show off your sophistication), the Sesame Street theme song, "Love Me Do" by The Beatles, "Deck the Halls", and more. There are hundreds of great melodies that only use C-Major.
