Altered Scale

Altered scales are used predominantly by jazz musicians to produce interesting tensions when improvising over dominant seventh chords. Altered scales are the same as jazz minor scales played a semitone higher, so you only really have to learn one to play the other. For example, the A altered Scale uses the same notes as a Bb jazz minor scale. If you know the Bb jazz minor scale, you also know the A altered scale!

Altered Scale Theory

An altered scale contains the same notes as a jazz minor scale played a semitone higher, e.g.: an G altered scale contains the same notes as an A flat jazz minor scale.

When played over Dominant Seventh chords, altered scales provide the following altered notes that will create tension: b5, #5, b9, #9

Notes in an altered scale

The notes in a G altered scale are: G, Ab, Bb, Cb, Db, Eb, F, G

The A flat and B flat are respectively the flat nine and sharp nine tones, the C flat and D flat notes are respectively the flat and sharp five notes.
