Though modulation generally refers to changes of key, any parameter may be modulated, particularly in music of the 20th and 21st century. Metric modulation (known also as tempo modulation) is the most common, while timbral modulation (gradual changes in tone color), and spatial modulation (changing the location from which sound occurs) are also ...
The music of Disc Jockey can be as well considered a modern example of modular music, where different and independent modules are mixed rather than overlapped, played simultaneously and the third modules represented by the Dj him/herself who interacts with the two ongoing modules (tracks).
Some pulse modulation schemes also allow the narrowband analog signal to be transferred as a digital signal (i.e., as a quantized discrete-time signal) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example, some line code. These are not modulation schemes in the conventional sense since they ...
In music, metric modulation is a change in pulse rate and/or pulse grouping (subdivision) which is derived from a note value or grouping heard before the change. ...
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.
In music, harmonization is the chordal accompaniment to a line or melody: "Using chords and melodies together, making harmony by stacking scale tones as triads". [2] A harmonized scale can be created by using each note of a musical scale as a root note for a chord and then by taking other tones within the scale building the rest of a chord. [3]
The word pulse in the term pulse-code modulation refers to the pulses to be found in the transmission line. This perhaps is a natural consequence of this technique having evolved alongside two analog methods, pulse-width modulation and pulse-position modulation , in which the information to be encoded is represented by discrete signal pulses of ...
The omnibus progression in music is a chord progression characterized by chromatic lines moving in opposite directions. [1] The progression has its origins in the various Baroque harmonizations of the descending chromatic fourth in the bass ostinato pattern of passacaglia, known as the "lament bass". [2]
