Diatonisation

Diatonisation is a musical technique used to create a sense of tonality or key within a piece of music that is otherwise atonal or non-tonal. This process involves the use of diatonic scales, which are scales consisting of seven notes that are arranged in a specific pattern, typically major or minor. By incorporating diatonic scales into a composition, a musician can establish a clear sense of tonality, even if the rest of the piece is atonal.

Diatonisation can be achieved through various means, including the use of diatonic chords, melodies, or harmonies. For example, a composer might use a diatonic chord progression to establish a key, even if the rest of the piece is composed of dissonant or non-tonal harmonies. Similarly, a melody that is otherwise atonal can be diatonised by incorporating diatonic scales or patterns.

Diatonisation is often used in contemporary music to create a sense of tonality or key within a piece that is otherwise atonal. It can also be used to create a sense of tension or release within a piece, as diatonic harmonies can create a sense of resolution or stability, even if they are used sparingly or in unexpected contexts.

In summary, diatonisation is a musical technique used to create a sense of tonality or key within a piece of music that is otherwise atonal or non-tonal. This process involves the use of diatonic scales, chords, melodies, or harmonies, and can be used to create a sense of tension or release within a piece.
