How to Compose Entire Bass Lines Using Only Whole Tone Scales

by

Composing bass lines using only whole tone scales offers a unique and intriguing sound that can add a surreal and mysterious quality to your music. The whole tone scale, consisting entirely of whole steps, creates an ambiguous and floating musical atmosphere. This article explores how to craft compelling bass lines within this scale, perfect for experimental and jazz compositions.

Understanding the Whole Tone Scale

The whole tone scale is built by stacking six whole steps. For example, starting on C, the scale is: C – D – E – F♯ – G♯ – A♯ – (and back to C). Because of its symmetrical structure, the scale lacks the traditional leading tones and creates a sense of ambiguity, making it ideal for creating tension and unresolved sounds in your bass lines.

Key Characteristics for Bass Lines

When composing bass lines in a whole tone scale, focus on the following characteristics:

  • Repetition of intervals: Use consistent intervals to create a hypnotic effect.
  • Minimal movement: Move stepwise or in small intervals to maintain cohesion.
  • Emphasis on tone color: Explore different positions and fingerings on your instrument to highlight the scale’s unique sound.

Steps to Compose a Bass Line

Follow these steps to craft your bass line:

  • Choose a root note: Decide on the starting point of your scale.
  • Establish a motif: Create a simple motif or pattern based on the scale’s intervals.
  • Develop the motif: Repeat and vary the pattern to build interest.
  • Use stepwise motion: Keep movement smooth and fluid, emphasizing the scale’s characteristic sound.
  • Experiment with rhythm: Incorporate different rhythmic patterns to add groove and dynamics.

Example Bass Line

Starting on C, a simple bass line could be:

  • C – D – E – F♯ – G♯ – A♯ – C (ascending)
  • C – A♯ – G♯ – F♯ – E – D – C (descending)
  • C – E – G♯ – A♯ – G♯ – E – C (arpeggio-like pattern)

By repeating and varying these patterns, you can create a hypnotic bass line that emphasizes the unique qualities of the whole tone scale.

Tips for Success

To make the most of your compositions:

  • Experiment with different starting notes: Each root creates a different mood.
  • Combine with other scales: Mix in chromatic passing tones for variety.
  • Focus on tone: Use dynamics and articulation to highlight the scale’s enigmatic sound.

Using only whole tone scales in your bass lines can lead to innovative and captivating musical ideas. Embrace the ambiguity and explore new sonic landscapes with these techniques.
