A smart music device and process provide users with an interface to play a selected song in the correct song key. The device includes a graphical user interface with areas demarcated by translucent conductive ink printed on the layer's underside. A layer of force sensor resistors (FSRs) are under the areas. Touching one of the areas closes a circuit between then conductive ink and FSR triggering a note to be played. The demarcated areas are illuminated to guide the user on scale and root node position. Metadata in memory storage includes the song key which is used during song playback to trigger assignment of the key correct scale across the FSRs and illuminate its root position of musical notes. Touching an area triggers a signal sent to a connected musical instrument to play the note.
