An ornamental tone following a principal tone by a skip up or down, usually of a third, and proceeding in the opposite direction by a step, not to be confused with changing tone. canon or kanon (Ger.) A theme that is repeated and imitated and built upon by other instruments with a time delay, creating a layered effect; see Pachelbel's Canon.
In music, the dynamics of a piece are the variation in loudness between notes or phrases.Dynamics are indicated by specific musical notation, often in some detail.However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece.
Historically, reverberation time could only be measured using a level recorder (a plotting device which graphs the noise level against time on a ribbon of moving paper). A loud noise is produced, and as the sound dies away the trace on the level recorder will show a distinct slope. Analysis of this slope reveals the measured reverberation time.
The louder sounds above the threshold remain unaffected. Some compressors also have the ability to do the opposite of compression, namely expansion. Expansion increases the dynamic range of the audio signal. [3] Like compression, expansion comes in two types, downward and upward. Downward expansion makes the quiet sounds below the threshold ...
Musical tones produced by the human voice and all acoustical musical instruments incorporate noises in varying degrees. Most consonants in human speech (e.g., the sounds of f, v, s, z, both voiced and unvoiced th, Scottish and German ch) are characterised by distinctive noises, and even vowels are not entirely noise free.
For example, sound moving through wind will have its speed of propagation increased by the speed of the wind if the sound and wind are moving in the same direction. If the sound and wind are moving in opposite directions, the speed of the sound wave will be decreased by the speed of the wind. The viscosity of the medium.
Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing.
A dynamic accent or stress accent is an emphasis using louder sound or stronger sound; typically, most pronounced on the attack of the sound. A tonic accent is an emphasis on notes by virtue of them being higher in pitch, as opposed to higher in volume. [1] An agogic accent is an emphasis by virtue of notes being longer in duration.
