14" A + C Gamma Acoustic Relationship Set

Two tones. One evolving field of sound.

This set includes two 14" frosted crystal singing bowls selected for their intentional musical and frequency relationship:

• One 14" A bowl tuned to 440 Hz
• One 14" C bowl tuned to 440 Hz
• Two silicone crystal bowl mallets
• Two protective O-rings

Unlike the same-note acoustic beating sets, this pairing brings together two different notes within the same tuning system. When sounded together, the relationship between A and C creates a faster pattern of acoustic interaction within the shared sound field.

This naturally occurring phenomenon emerges through the interaction of the bowls’ frequencies.

Rather than remaining completely still, the combined sound develops a rich sense of texture, movement and tonal complexity. The relationship may be perceived as a rapid acoustic shimmer within the surrounding sound.

The result is a listening experience that may feel:

• Bright and multidimensional
• Active and harmonically complex
• Rich in movement and texture
• Dynamic rather than static
• Supportive of focused and engaged listening

Why Acoustic Beating?

The term binaural beat is often used broadly within the sound wellness community. Technically, however, binaural beats are generally created when two different tones are delivered separately to the left and right ears, most commonly through headphones.

These crystal bowls create something different.

Because both tones are sounded together in the same physical space, their sound waves interact acoustically. The resulting movement can be heard within the room without headphones.

For this reason, Mystic Meditations refers to these collections as Acoustic Beating Sets.

The Gamma Relationship

The frequency relationship created by this pairing produces an acoustic interaction of approximately 41 Hz, within the gamma range.

Gamma activity is commonly associated with active states of awareness, including:

• Focused attention
• Cognitive engagement
• Information processing
• Heightened awareness
• Integrated sensory experience

The bowls do not generate a specific brainwave state or produce the same experience for every listener. Instead, their tonal relationship creates a distinctive acoustic environment that may complement focused listening, creative exploration and intentional sound practices.

The Sound of Frosted Quartz

Frosted quartz crystal singing bowls produce a strong, sustained tone with rich harmonic content.

Their volume, resonance and long decay allow the relationship between these two tones to be clearly perceived. The interaction may be heard as a rapid shimmer, added texture or subtle movement within the surrounding sound field.

Each bowl may also be played independently or incorporated into a larger crystal singing bowl collection.
