Alteration

Alteration is the process of changing the form or content of a musical work. This can be a change in key, size, tempo, harmony, rhythm and other elements of music. Alteration can be used to create new musical images, as well as to express the emotions and feelings of the composer.

Alteration can be used both in classical and modern music. For example, in jazz music alteration is used to create unusual harmonies and rhythms. In rock music, alternation is often used to create tension and dynamics in the music.

One of the most famous examples of alteration is the use of alteration in Bach's music. He used alterations to create unusual harmonic combinations and to express his emotions. Alteration is also widely used in modern music, for example, by composers such as John Cage and Luciano Berio.

Alteration is a concept in music that means modification, arrangement of a musical work created by other composers, other (usually alien, but in some cases organically introduced) content into a musical work, or modification of a mood or harmonic theme while maintaining its form and structure. Typically performed in opera, ballet, symphonic or choral works. It is also found in some chamber musical works, in couplets of opera parts and romances. To characterize changes and additions in a musical text, the adjective “alternative” is used, that is, “different”. For example, “Mozart created an alternative form of symphony - one-movement.”

Altergeist is a genre of horror literature in a fantasy setting, beginning with a fantastic investigation into a criminal event and leading to the characters’ gradual contact with supernatural forces. In addition to the work of Joss Whedon, there is a literary altergeist for adult audiences known as alterism.
