Square Wave
A square wave is a periodic [waveform] characterized by its square-like shape and binary, discrete nature.
Sound
A square wave is formed by summing only the odd [partial]s of the [harmonic series], where each of the odd [harmonic]'s [amplitude] is inversely proportional to its [frequency].
- amplitude of the $n$th harmonic = $\frac{1}{n}$
The [timbre] of a square wave is distinctly hollow, like a clarinet or closed-end organ pipe
