Modulations

Modulations refer to the alterations or changes in the characteristics of something, typically in the context of sound, signal, or expression. This can involve variations in amplitude (loudness), frequency (pitch), phase, or other parameters. The term emphasizes the dynamic and shifting nature of the subject, reflecting a process of adjustment and adaptation. In music, modulations describe shifts in key. In radio transmission, modulations encode information onto a carrier wave. In speech, modulations refer to the rise and fall of the voice. They can range from subtle to dramatic, conveying information, emotion, and variety.
