Question

1. what are harmonics in terms of musical sound?

a. the lowest frequencies in a sound
b. the fundamental tones only
c. random frequencies unrelated to the fundamental
d. integral multiples of the fundamental frequency

Explanation:

In musical sound, harmonics are frequencies that are integral multiples of the fundamental frequency. The fundamental frequency is the lowest - pitched component of a complex sound. Option a is incorrect as harmonics are not the lowest frequencies (the fundamental is the lowest). Option b is wrong because harmonics are not just the fundamental tones; they are additional tones. Option c is incorrect since harmonics are related to the fundamental frequency (by being its multiples), not random.

Answer:

d. Integral multiples of the fundamental frequency
