a clef which marks the position of the pitch G on the staff (Fig. 1). Most commonly, the clef is positioned so that the large loop of the G-clef is on the second line of the staff, indicating that this line now signifies the pitch G. In this position, we call it the “treble-clef” (Fig. 2). This clef is moveable, however, it is rarely used as a moveable clef. If the clef is moved up or down the staff, whichever line is in the center of the large loop will signify the pitch G (Fig. 3).
