The guitar is one of the most widespread instruments amongst autodidacts, but even though a huge amount of learning material exists, it is still hard to learn especially without a guitar teacher. In this paper we propose an Augmented Reality application called guitAR that assists guitar students mastering their instrument using a projector phone. With the projector phone mounted at the headstock of the guitar, the fret board and the strings of the guitar are in the field of projection of the phone. By projecting instructions directly onto the strings of the guitar the user is easily able to realize where the fingers have to be placed on the fretboard (fingering) to play a certain chord or a tone sequence correctly.
