Tone refers to the degree of lightness or darkness in an area, ranging from bright white to deepest black. How we perceive the tone of an object depends on factors like its surface, lightness, darkness, color, and texture. Students are assigned to complete two sustained tonal drawings - one using tonal pencil and one using tonal chalk. They must also complete a page on an artist who works in black and white using a good tonal range. Additional optional work includes creating observational tonal drawings in a range of media in their sketchbook.
