Designed for Practitioner Use

A complete scale provides greater flexibility when designing and facilitating sound experiences.

This collection supports:

• Harmonic and melodic exploration
• Layered sound facilitation
• Movement between neighbouring notes
• Building tension and resolution
• Creating gradual tonal transitions
• Structured and intuitive sound practice
• Individual and group sound sessions

The seven-bowl format offers a broad tonal vocabulary while remaining centred within one octave.

Frosted Crystal Tone

Frosted quartz crystal singing bowls produce strong, sustained tones with rich harmonic overtones.

Their resonance and projection allow the bowls to be played individually, sequentially or in layered combinations.

Each collection is selected for tonal compatibility and consistent tuning across the complete scale.
