Which term describes tones that are multiples of the basic tone and contribute to timbre?

• A. Overtones
• B. Harmonics
• C. Fundamentals
• D. Partial Tones

Answer: (A)

Timbre is shaped by the spectrum of frequencies that accompany the fundamental pitch. The tones that are multiples of that basic tone—2x, 3x, 4x, and so on—form the higher parts of the harmonic series. These overtones, though not changing the pitch, color the sound and give instruments their distinct character because their relative strengths differ. The fundamental is the base pitch, while overtones are the additional frequency components above it that contribute to timbre. While terms like harmonics or partial tones are related, the most direct description for tones that are multiples of the basic tone and affect timbre is overtones.
