What is the fundamental?

• A. The loudest, lowest, and strongest frequency in a pitch
• B. The highest partial
• C. The overtones only
• D. The same as the pitch center

Answer: (A)

The fundamental is the base frequency of a note—the lowest frequency present. In a musical tone, you have this fundamental plus higher frequencies called overtones or harmonics, which are whole-number multiples of the base frequency. The fundamental sits at the bottom of that spectrum and often carries the strongest energy, so it largely determines the pitch you perceive. The higher partials shape the tone’s color or timbre, but they don’t define the basic pitch as directly. So the fundamental is the lowest, and typically the strongest, frequency that defines the note.
