The altered scale is a powerful tool in modern bass playing, especially on a 6-string bass. It allows bassists to add tension and color to their lines, creating more expressive and complex sounds. Understanding how to use this scale can significantly enhance your musical vocabulary and improvisational skills.
What Is the Altered Scale?
The altered scale, also known as the superlocrian scale, is a mode derived from the melodic minor scale. It consists of a root, a flattened second, a flattened third, a flattened fifth, a flattened sixth, and a flattened seventh. This scale is typically used over dominant chords with altered tensions, such as 7♯9, 7♭9, or 7♯5.
Why Use the Altered Scale on a 6-String Bass?
The 6-string bass extends the range of the instrument, allowing bassists to access higher notes and create more melodic lines. Using the altered scale in this context provides a richer palette for expression, especially when soloing or comping over complex chords. It enables the bassist to add dissonance and tension that resolve beautifully within a musical progression.
Advantages of the 6-String Bass
- Access to higher registers for melodic lines
- Enhanced harmonic possibilities
- Greater flexibility in improvisation
- Ability to play complex scales and modes easily
How to Incorporate the Altered Scale
Start by learning the scale patterns across the fretboard. Practice applying the altered scale over dominant chords in different keys. Focus on resolving dissonant notes to more stable tones to create tension and release. Incorporate the scale into your improvisations during jam sessions or recordings to develop your ear and technique.
Practical Tips
