diatonisena

Diatonisena is a term used in music theory to describe a scale that is derived from the diatonic scale but with a specific alteration. The diatonic scale is a seven-note scale that is the foundation of Western music, consisting of the notes A, B, C, D, E, F, and G. The diatonisena scale is formed by raising the third degree of the diatonic scale by a semitone. This alteration creates a unique sound that is often used in various musical genres, including jazz and classical music.

The diatonisena scale can be constructed from any major or minor key. For example, in the key of C major, the diatonisena scale would be C, D, E♯, F, G, A, B. In the key of A minor, the diatonisena scale would be A, B, C♯, D, E, F, G. This scale is also known as the altered scale or the whole-tone scale in some contexts, although the term "whole-tone scale" typically refers to a different scale with a different structure.

The diatonisena scale is used in various musical contexts, including improvisation, composition, and arrangement. It provides a unique sound that can add color and interest to a piece of music. Musicians often use this scale to create tension and release, as the altered third degree can create a sense of dissonance that is resolved by the other notes in the scale. The diatonisena scale is a versatile tool that can be used in a variety of musical styles and genres.
