designer's own words:The melody door brings the fun and customization of ringtones to your home. Now anyone announcing themselves with a knock can be as playful as the want to be. Ever wanted to tap out "Taps" to wake someone up in the morning? Or how about chopsticks? One full octave of notes gives you a range of choices, while the design of the door fits nicely with a modernist aesthetic. With melody your knock is as unique as you are.
