Augmented Scale: A symmetrical musical scale constructed by alternating whole and half steps. This structure gives the scale a unique and somewhat dissonant sound, often used to create tension in compositions.

Context and Significance

The augmented scale is significant in jazz and modern classical music due to its ability to produce intriguing harmonic and melodic colors. Its alternating whole and half steps create a sense of ambiguity and tension, making it a powerful tool for musicians seeking to add complexity to their compositions. Jazz guitarists and pianists frequently use the augmented scale to craft solos that stand out with their distinctive sound.

Historical Background

The augmented scale emerged from the exploration of symmetrical scales in the 19th and 20th centuries. Composers like Franz Liszt and later jazz musicians experimented with this scale to generate novel harmonic landscapes. Its symmetrical nature allows for seamless transposition and modulation, which became particularly appealing in the development of modern jazz and avant-garde music.

Examples

In jazz, the augmented scale is often employed by musicians such as John Coltrane and Miles Davis. Coltrane’s “Giant Steps” showcases the scale’s potential for creating complex harmonic progressions. Classical composers, including Olivier Messiaen, have also utilized the augmented scale in works like “Mode de valeurs et d’intensités,” where it contributes to the piece’s avant-garde character.
