Etymology
The word 'modulation' traces its lineage to the Latin noun modulus, meaning a small measure or standard, itself derived from modus (measure, manner). The core concept is one of measured, proportionate change. In music, this evolved to signify the measured, systematic transition from one key to another. This logic of controlled variation extended into broader technical and general use, referring to the process of adjusting the frequency, amplitude, or other property of a wave, or to the measured alteration of one's voice in speech.
