Four Bowl Key Of C Harmonic Binaural Crystal Singing Bowl Set
A Therapeutic Approach
This 4-bowl set combines two foundational approaches to sound work: harmonic relationships and binaural interaction.
Each bowl is selected for its clarity of tone and precise tuning—creating a sound field that is both stable and dynamic.
What This Set Includes
2x 14" C, 1x 12" E and 1x 10" G
These combine to make both a harmonic, and a binaural set. One 14" C pairs with the 12" E and 10" G to make a harmonic set. You can choose to have this in 440hz or 432hz. You will then get a second 14" C bowl that will make a 6hz theta binaural when the two 14" C bowls are played together.
Harmonic Field
With three unique tones available, this set forms a complete harmonic structure.
This creates a sound field that is:
- full and balanced
- rich in harmonic content
- immersive and continuous
The presence of the third and fifth introduces both stability and tonal color, creating a more complete harmonic experience.
Binaural Field
The paired root bowls introduce a subtle oscillation when played together.
This adds:
- a gentle rhythmic pulse within the sound
- a sense of internal movement
- a shift in perception and awareness
The binaural effect exists within the harmonic field, adding depth without disrupting coherence.
Working in Practice
This set allows for multiple approaches:
- establishing a full harmonic field
- introducing binaural pulsing within that field
- moving between stillness and motion
You can move between:
- coherence → depth → integration
A Balanced System
With four bowls, the experience becomes:
- more immersive than a 3-bowl set
- more structured than larger systems
- balanced between simplicity and depth
A system that offers both:
- stability and movement
- within the same field.
Quality & Craft
Each bowl undergoes multiple quality checks for:
- tone clarity
- ease of play
- surface quality
- tuning accuracy
Ensuring each set functions as a cohesive and reliable instrument.
