Code: U312D2

Note: The "Ultabati" category remains a topic of fascinating debate among antiquities scholars. While some research suggests these large, flared-rim vessels originally served domestic or utilitarian purposes in the Himalayas, their acoustic properties are undeniable. This captivating ambiguity only adds to the unique history of the piece.

Historical Classification & Form

• Type: Ultabati

• Form Profile: Features a sweeping, expansive calabash silhouette with a distinctive under-rim curvature. This structural contour creates a massive acoustic chamber designed for maximum bass resonance.

Musical Signature & Acoustics

• Fundamental Pitch: D2 (Sub-bass range)

• Sonic Profile: Emits a profoundly deep, primordial "Ohm" vibration that offers exceptional grounding qualities for therapeutic sound work.

• Acoustic Presence: This instrument commands the room with a powerful, immersive sonic presence. The expansive bronze walls allow the ultra-low D2 frequencies to build smoothly and sustain beautifully, washing over the listener in deep, undulating waves of sound.

Physical Specifications

• Diameter: 31.2 cm

• Weight: 2.1 kg

• Architecture: The generous 31.2 cm aperture combined with a substantial 2.1 kg mass provides the exact physical volume needed to support ultra-low, sustained acoustic energy cleanly, without distortion.

Patina & Surface Characteristics

• Exterior Aesthetics: Showcases a striking visual contrast, featuring a deep, dark charcoal finish along the lower basin that transitions gracefully into a lighter, golden-bronze band just below the rim.

• Interior Finish: The interior reveals a warm, golden brass complexion that catches the light beautifully, highlighting centuries of natural aging.

• Artisanal Markings: Prominent, authentic hand-hammering marks are visible across the entire surface, showcasing the immense master-craftsmanship required to forge a bronze vessel of this scale.

Archival Notes

• A rare find of impressive scale and low-frequency gravity. The combination of visual drama, historical mystery, and deep acoustic power makes this an extraordinary foundational instrument for any dedicated sound therapist or collector.
