Wavelength

Every essay has a rhythm. Short sentences punch. Long ones flow and carry you through a thought that builds and builds until the period arrives like a shore. This page measures that — sentence length as waveform, the frequency and amplitude of prose.

Prose has a heartbeat. Short sentences are systole — contraction, force, impact. Long sentences are diastole — expansion, breath, the thought unfurling. The best writing alternates between them the way a heart alternates between compression and release. Not because someone planned it, but because rhythm is how meaning moves through language.
