There are two of these accentors, one at eachend of the player, and in their operation theydiffer completely from those accenting devices Ihave already described. The Pistonola accentoremphasizes the melody notes without cutting downthe tension. The treble and bass buttons, also, donot reduce but increase the power. If you glance. H
