What chords can you play altered scale over? This is a question that often arises among musicians looking to expand their harmonic palette and explore more complex and expressive sounds. The altered scale, also known as the super locrian mode, is a seven-note scale that is derived from the diminished scale by raising the sixth and seventh degrees by a half step. This creates a unique and dissonant sound that can be used over a variety of chords to add depth and tension to your music.

The altered scale can be played over a wide range of chords, but some of the most common include:

1. Dominant 7th Chords: The altered scale is a perfect fit for dominant 7th chords, as it provides a rich and complex sound that can add tension and release. It can be used over dominant 7th chords in all keys, such as G7, Bb7, and E7.

2. Minor 7th Chords: The altered scale can also be used over minor 7th chords, particularly those that have a diminished quality. For example, it works well over Dm7b5, Cm7b5, and Abm7b5.

3. Diminished 7th Chords: Since the altered scale is derived from the diminished scale, it is naturally suited for diminished 7th chords. It can be used over chords like Bdim7, Ebdim7, and Abdim7 to create a sense of tension and resolution.

4. Major 7th Chords: While the altered scale is not traditionally used over major 7th chords, it can still be an interesting choice for adding dissonance and tension. It works well over chords like A7, E7, and G7 when you want to explore a more complex harmonic language.

5. Augmented Chords: The altered scale can also be played over augmented chords, such as C+ and E+. This combination creates a dissonant and unresolved sound that can be used to great effect in more avant-garde or experimental music.

When playing the altered scale over these chords, it’s important to consider the overall harmonic context of your music. The altered scale can add tension and release, so it’s best used in moderation and in combination with other chords and scales. Experimenting with different inversions and fingerings can also help you find the most expressive and musical way to play the altered scale.

In conclusion, the altered scale is a versatile and powerful tool for any musician looking to expand their harmonic vocabulary. By understanding which chords it works well over, you can create more complex and expressive music that pushes the boundaries of traditional harmony. So, the next time you ask yourself “what chords can you play altered scale over?” remember that the possibilities are endless, and the only limit is your imagination.
