Two musical sounds are said to produce harmony when, on being sounded together, they produce a result pleasing to the ear. If the result is displeasing, they are said to produce discord. One cause of discord is the presence of beats between the two tones, and the greatest discord, between tones of medium pitch, results when the beats are about 32 per second; if the number of beats is fewer than 10 or greater than 70 per second, they are somewhat unpleasant but do not produce discord.
