The guitar, QRCoda, takes its name in part from the music notation of a coda. Represented by a set of crosshairs, a coda is used as a navigation marker in modern music. When instructed to go "To Coda" the musician, upon reaching the final repetition of a section of music, jumps immediately to a separate section headed with the coda symbol.

In the instance of the guitar, QR Codes instruct mobile devices to go "To Coda" and jump to interactive content on the internet.
