The extended range delivers the broadest tonal palette available in a shruti box, giving the player room to build deep grounding drones in the lower octave, supportive mid-range chord beds, and bright carrying tones in the upper octave, all from a single instrument. This makes the three-octave box the natural choice for serious practitioners, professional sound therapists, working musicians, and recording artists who need a single drone instrument capable of supporting any vocal range, any key, and any layered harmonic arrangement. It excels in studio work where the drone needs to sit in specific frequency pockets, in ensemble settings where multiple vocalists or instruments require different anchor tones, in advanced sound therapy sessions where the practitioner shifts between octaves to work different energy centers, and in any kirtan or devotional setting where the music moves freely through changing keys. The larger body also delivers exceptional resonance and bellows capacity, with strong projection that carries through large rooms, group sessions, and live performance settings without losing presence. Crafted from solid teak with metal corner reinforcements and a polished finish, the box is built to hold its tone and travel well for years of regular use.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe shruti box has its roots in the classical music traditions of India, where it evolved as a portable hand-pumped reed instrument designed to hold a steady drone behind vocalists and other musicians. Its name comes from the Sanskrit word shruti, meaning \"that which is heard,\" a term that in Indian musical theory refers to the smallest perceptible interval of pitch and to the foundational tones around which raga melodies are built. Historically, the shruti box replaced the older tanpura in many traveling settings, since it offered the same continuous drone in a far more compact and durable form. Today the instrument is used well beyond its classical origins, finding a place in sound therapy, meditation, kirtan and devotional singing, yoga and chanting practice, songwriting, and any setting where a sustained, breathing drone is needed to anchor voice or melody.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003ePlease note that the Thetazen Shruti Box is handcrafted from solid wood by skilled artisans, and small variations from instrument to instrument are a natural part of that process. \u003c\/span\u003e\u003c\/div\u003e","brand":"HK Higher Knowing, LLC","offers":[{"title":"Default Title","offer_id":67782841630890,"sku":null,"price":409.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1117\/0846\/files\/large440shruti1.webp?v=1793306242"},{"product_id":"large-440hz-26-note-two-octave-c3-c5-thetazen-shruti-box","title":"Large 440Hz 26-Note Two Octave C3-C5 Thetazen Shruti Box","description":"\u003cdiv\u003e\u003cspan\u003eLarge 440Hz 26-Note Two Octave C3-C5 Thetazen Shruti Box with Carry Case\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e• Size: 16.25\" x 12.5\" x 3.5\"\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e• Average weight: 3810g\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e• Scale: Third Octave and Fourth Octave 26-Note C3-C5\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e• Includes: Carrying Case\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThis is the large two-octave model in our Thetazen Shruti Box lineup, tuned to 440Hz with a full 26-note range spanning two octaves from C3 to C5 (covering the complete chromatic scale across both octaves, plus the upper C). The extended range opens up significantly more tonal flexibility than the single-octave models, letting the player build richer harmonic beds, support a wider range of vocalists, and shift between lower grounding tones and higher carrying tones within the same instrument. This makes the two-octave box especially well suited to practitioners who work with multiple singers, sound therapy sessions where the drone needs to move between root and upper-register tones, kirtan and devotional music with shifting keys, and recording or performance settings where one instrument needs to cover what would otherwise require two. The larger body also delivers the fullest, most resonant voice in the lineup, with deep bellows capacity and strong projection that carries through larger rooms and group settings without losing presence.

Variation in wood grain, color, finish tone, and slight shifts in hardware placement are normal and expected, and may differ a little from the photos shown. Every box is tested and tuned before it ships, but because the reeds are set by hand, subtle differences in tone and bellows response are part of what gives each instrument its own character rather than making it a copy of the next.

The third octave sits in the lower-mid vocal range, which makes this size especially well suited to chant work, mantra practice, kirtan, and any setting where the drone needs to support a male vocal range or sit beneath a singer rather than above. The lower tonal placement also gives the drone a grounding, meditative quality that pairs naturally with sound therapy sessions, breathwork, yoga nidra, and contemplative practice. The medium size strikes a practical balance in the lineup, offering a fuller resonance and stronger bellows projection than the smallest box while remaining easy to carry to retreats, sessions, classes, and group circles. Crafted from solid teak with metal corner reinforcements and a polished finish, the box is built to hold its tone and travel well for years of regular use.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe shruti box has its roots in the classical music traditions of India, where it evolved as a portable hand-pumped reed instrument designed to hold a steady drone behind vocalists and other musicians. Its name comes from the Sanskrit word shruti, meaning \"that which is heard,\" a term that in Indian musical theory refers to the smallest perceptible interval of pitch and to the foundational tones around which raga melodies are built. Historically, the shruti box replaced the older tanpura in many traveling settings, since it offered the same continuous drone in a far more compact and durable form. Today the instrument is used well beyond its classical origins, finding a place in sound therapy, meditation, kirtan and devotional singing, yoga and chanting practice, songwriting, and any setting where a sustained, breathing drone is needed to anchor voice or melody.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003ePlease note that the Thetazen Shruti Box is handcrafted from solid wood by skilled artisans, and small variations from instrument to instrument are a natural part of that process.
