Incorporating whole tone scales into bass soloing can add a unique, floating sound to your improvisation. This approach works especially well over dominant chords and jazz progressions that call for a mysterious or ambiguous tone. Understanding how to use these scales effectively can elevate your bass playing and provide fresh harmonic ideas.
Understanding the Whole Tone Scale
The whole tone scale consists of six notes, each separated by a whole step. Unlike major or minor scales, it has a symmetrical structure, which creates a sense of ambiguity and dreamlike quality. The scale can be built starting from any root note, but the most common is:
- Root
- Whole step
- Whole step
- Whole step
- Whole step
- Whole step
- Back to root
For example, a C whole tone scale would be: C, D, E, F#, G#, A#, and back to C. This symmetrical pattern makes it easy to transpose and adapt over different chords.
Applying Whole Tone Scales Over Chord Changes
While the whole tone scale is often associated with jazz and impressionist music, it can be effectively used over dominant chords, especially those with altered tensions. When soloing, consider the following tips:
- Use the scale over dominant seventh chords to add a mysterious or unresolved sound.
- Target specific notes within the scale that highlight tension tones like #5 or #7.
- Experiment with shifting the scale to fit different roots as the harmony changes.
Example: Soloing Over a Dominant Chord
Suppose you’re soloing over a G7 chord. You can use a G whole tone scale: G, A, B, C#, D#, F, and G. Focus on emphasizing the C# and D# notes to highlight altered tensions, creating a more colorful sound.
Integrating Whole Tone Scales into Your Playing
To effectively incorporate whole tone scales, practice them slowly over backing tracks or with a metronome. Try improvising simple motifs or motifs based on the scale’s intervals. Over time, you’ll develop a more intuitive feel for when and how to use these scales in your solos.
Remember, the key to mastering the whole tone scale is experimentation. Use it to add color and interest to your bass solos, especially when aiming for a surreal or unresolved sound.
