How to Use the Altered Scale in Jazz

The altered scale, also known as the diminished scale, is a powerful tool in the jazz musician’s arsenal. It adds a unique flavor to improvisations and can transform a simple melody into a sophisticated musical statement. In this article, we will explore how to use the altered scale in jazz, including its origins, structure, and practical applications.

The altered scale is derived from the diminished scale, which is a seven-note scale that spans an octave. The diminished scale is characterized by alternating whole and half steps, which creates a sense of tension and resolution. To create the altered scale, you start with the diminished scale and then flatten the third, fifth, and seventh notes. This results in a scale that contains a combination of major and minor second intervals, creating a rich and complex sound.

Understanding the Structure of the Altered Scale

The altered scale consists of the following notes: root, minor second, major second, minor third, flat fifth, flat seventh, and major seventh. The key to using the altered scale effectively is to understand its intervals and how they interact with other scales and chords. For example, the altered scale can be used over dominant seventh chords, providing a unique approach to improvisation.
