Nada Yantra - Chakra Resonance Workstation
Nada Yantra - Chakra Resonance Workstation
Nāda Yantra — a resonance instrument for the seven chakras. A pure-synthesis chakra instrument that weaves tanpura, singing bowls, and brainwave entrainment into a single living drone — tuned to breathe with you.
Choose a gate and the instrument awakens — a tanpura turning beneath a reed pad, a flute breathing somewhere in the distance, singing bowls struck from the gate's own pitch. Underneath it all, a brainwave-entrainment carrier and a slow breath pacer move together, so that color, sound, and breath fall into one rhythm. Nāda Yantra isn't a playlist or a loop; it's an instrument you settle into. Sit with a single chakra to hold an intention, or surrender to a guided journey that rises through all seven gates of the sushumna.
What it is
Built entirely from live synthesis — not a single sample — Nāda Yantra generates everything you hear in the moment: a cyclic tanpura drone, a sustained harmonium pad, a breathy bansuri voice with a slow generative rāga, inharmonic singing-bowl strikes, and a high airy shimmer. Every voice retunes to the gate you select, anchored in either standard 440 Hz or the warmer 432 Hz. The result is a sound bath that never quite repeats and never runs out.
Feature highlights
Seven gates, fully voiced Each chakra carries its own note, color, element, and seed-sound. Select a gate and the whole instrument retunes around it; the on-screen yantra glows to match.
Living, sample-free sound Tanpura, harmonium, bansuri, singing bowls, and shimmer — pure Web Audio synthesis with a slow, ever-shifting generative melody. Nothing loops. Nothing repeats.
Brainwave entrainment, woven in Binaural and isochronic carriers sit beneath the music, each gate carrying a default target rate (theta, alpha, gamma). A depth control lets the pulse stay subtle under the drone or step gently forward. (Binaural beats are best experienced on headphones.)
A breath that paces you The yantra expands and softens with an adjustable breath pacer — set it near five to six breaths a minute for a slow, settling rhythm — with an optional ujjayi-style ocean cue to breathe along with.
Studio space and movement A convolution reverb engine (Hall · Cavern · Cloud · Canyon) with adjustable mix and decay, plus a lowpass filter with an optional LFO that breathes the tone open and closed.
432 or 440 Hz, your choice Switch concert pitch with a single toggle. Only the musical pitch shifts — the entrainment beat-rates stay exactly where they are.
Save the whole panel "Save Current Settings" captures every control — gate, voices, entrainment, filter, reverb, breath, tuning — and recalls it instantly. Your presets persist between sessions.
Atrium-ready, or standalone Run it on its own, or route its output to AudioSpire CH4 to feed the Atrium mixer — one button, no setup.
A guide built in An in-app companion covers the history of the chakras, a full table of traditional and modern correspondences, and a clear, honest primer on how brainwave entrainment actually works.
