6.5-7.75" 2-Note Zen Bioconcert Series Singing Bowl Set #zbcset111
This 2-bowl Zen BioConcert harmonic set features the notes F# and C, creating a bold and expressive tonal pairing with depth, contrast, and natural movement. The ZBC900 bowl carries a strong, grounding fundamental supported by a beautifully clear overtone, while the ZBC700 offers a focused, projecting tone with rich harmonic presence. Each bowl produces a dominant fundamental — the lowest primary tone — accompanied by an audible overtone that adds shimmer and dimensionality to the sound.
What makes this pairing especially compelling is that the luminous overtone of the ZBC900 aligns beautifully with the fundamental of the ZBC700, creating a natural octave relationship between the bowls. This octave reinforcement strengthens the resonance field and allows the tones to lock in with clarity and cohesion while still preserving the expressive tension between F# and C. When played together, the bowls produce a layered, immersive soundscape that feels powerful, spacious, and harmonically alive.
