6.5-8" 2-Note Zen Bioconcert Series Singing Bowl Set #zbcset110
This 2-bowl Zen BioConcert harmonic set features the notes D# and A, creating a bold and spacious tonal relationship built on contrast and openness. Rather than a close stepwise progression, this pairing forms a wider interval that introduces both grounding presence and expansive lift, giving the set clarity and depth. Each bowl carries a strong fundamental — the lowest dominant tone — supported by a clearly audible overtone that adds shimmer and harmonic richness, allowing the sound to feel dimensional and alive.
The interplay between D# and A creates a resonant dialogue that feels stable yet expressive, with subtle internal movement generated by their overtone structures. This configuration is ideal for practitioners who appreciate strong interval relationships and a clean, open sound field. When played together, the bowls blend into a cohesive yet spacious resonance that feels immersive, balanced, and dynamically engaging.
