A micro-practicing device emulates a portion of a full size instrument. The micro-practicing device includes a fingerboard with fret wires dividing the fingerboard into frets. In order to emulate the portion of the full size instrument, a length of each fret substantially matches lengths of frets of full size instruments. At the same time, the fingerboard is sized to enable increased portability. The device includes capacitive sensors adapted to detect the longitudinal and transverse positions of the user's fingers on the frets, and to communicate that positional information to a body portion. The body portion transmits the positional information to an external musical module, which converts the positional information into musical tones.
