'''Frequency''' refers to the rate at which a sound wave vibrates, expressed in **Hertz (Hz)** — cycles per second. It is the fundamental physical property that determines the perceived pitch of a sound.

== Frequency and Pitch ==
There is a direct relationship between frequency and [[Pitch]]:
* Higher frequency = higher perceived pitch
* Lower frequency = lower perceived pitch

For example:
* A₄ = 440 Hz
* A₃ = 220 Hz
* A₅ = 880 Hz

Each octave corresponds to a **doubling** of frequency.

== Role in Music ==
* Frequencies define the tuning of notes in a [[Scale]].
* Musical intervals are based on frequency ratios (e.g., 3:2 for a perfect fifth).
* Accurate frequency standards are essential for orchestral tuning, recording, and synthesis.

== Related Terms ==
* [[Pitch]] — perceptual counterpart of frequency
* [[Hertz]] — unit of frequency
* [[Tuning System]] — organizes frequencies across instruments
* [[Sound Wave]] — physical carrier of frequency in air
