Answer:
2
Explanation:
So "overtone" is an umbrella term, and there are two types of overtones: (1) "harmonic" overtones (which are integer multiples of the fundamental frequency) and (2) overtones that aren't integer multiples of the fundamental frequency (I'll call these disharmonious overtones)
Mezzotint’s tone is created using a special tool, like with drypoint. As the tool moves along the metal surface, it roughs the surface and creates different levels of grooves. When ink is applied to the surface, the varying levels of grooves provide the illusion of various tones and half-tones, while still using the same color of ink. This method is one of the best representation of monochromatic art.
