Tonal sketching is completely different to Cross Hatching and Hatching because the lines are not visible when one sketches according to this technique. Tonal sketching involves sweeping the pencil across the paper, back and forth in a flowing and fluid manner, to achieve a certain effect. Using different pressure levels on the pencil, one can create darker and lighter tones as the effect will be darker the harder one presses and lighter when one is not exerting as much pressure on the pencil. In addition to the pressure used, one must also consider the graphite scale when engaging in tonal sketching.
