In historical linguistics, a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound (or, more generally, one phonetic feature value) by a different one (called phonetic change) or a more general change to the speech sounds that exist (phonological change), such as the merger of two sounds or the creation of a new sound.
The extremely common approximant sound [j] is sometimes subject to fortition; since it is a semivowel, almost any change to the sound other than simple deletion would constitute fortition. It has changed into the voiced fricative [ʝ] in a number of indigenous languages of the Arctic , such as the Eskimo–Aleut languages and Ket , and also in ...

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.
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 sounds involved in a chain shift can be ordered into a "chain" in such a way that after the change is complete, each phoneme ends up sounding like what the phoneme before it in the chain sounded like before the change. [specify] The changes making up a chain shift, interpreted as rules of phonology, are in what is termed counterfeeding order.
A sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones).Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, [1] therefore sonority is often related to rankings for phones to their amplitude.

Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [1] [2] [3] psychophysics, [4] organology [5] (classification of the instruments), physiology, [6] music theory, [7] ethnomusicology, [8] signal processing and instrument building, [9] among other disciplines.
