In music, modulation is the change from one tonality ( tonic, or tonal center) to another. This may or may not be accompanied by a change in key signature (a key change ). Modulations articulate or create the structure or form of many pieces, as well as add interest.
Learn the various meanings and uses of the word modulation, from voice inflection to musical key change to radio signal processing. See examples, synonyms, word history, and related phrases.
Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height, or amplitude, and frequency. How modulation works.
Modulation. Types Of Modulation. Amplitude Modulation (AM) Angle Modulation. Frequency Modulation (FM) Phase Modulation (PM) The Modulation Concept. The modulation concept comes into consideration when the signal needs to be transmitted over a long distance through an antenna. Antenna helps transmit the signal over long distance.
Sep 1, 2007 · In this article, I will confine the discussion to actual key changes and explore five techniques for modulating: direct, pivot-chord, melody driven, transitional, and combination modulations. No matter which technique you use to create a modulation, you need to ask three questions: (1) What is the desired effect?
