 The viola uses the alto clef, while the cello uses the tenor clef; the confusing thing, of course, is that the two clefs look the same: the difference is that the alto clef is centered on the middle line of the staff, while the tenor clef is centered on the next line up.  Fortunately, this means that the picture is correct because it has the tenor clef.   04:02
