Air Qin · Stringless Guqin

Camera meets hands, strings in the air. Seven strings and thirteen hui float before you. Record a piece, seal it in vermilion, share it with a kindred spirit.

Air Qin — a guqin suspended in the air.

Open the camera and seven strings with thirteen hui appear before you. Raise a hand and the qin answers—no instrument, no strings; your body is the instrument.

THE INSTRUMENT — ALWAYS FREE · Seven strings, thirteen hui at true string-length ratios, standard tuning · San (open), pressed, harmonics, sliding tones, rolls, damping—gestures are the fingering · Point to press, pinch for harmonics, fist to pass silently, heart-sign to record · Predictive plucking engine—gesture and sound nearly in sync · A voice like jade chimes and bone flutes: string inharmonicity, sympathetic resonance, and body resonance, each with a physical origin · Record a video of playing in the air, sealed with a vermilion stamp, and share it

GUIDED START In seven steps, from your first wave of sound to playing the opening of "Xianweng Cao"—two minutes from zero, and you earn your first seal.

A PATH OF PRACTICE Four volumes of scores, four stars per piece (finish · 80% · flawless · blind score), a daily phrase, and a chapter map—every piece you play becomes a mark.

ZHIYIN (KINDRED SPIRIT) — ONE-TIME PURCHASE All three score volumes, with new pieces added over time; Carve your own one-to-four-character seal, stamped on every recording; "Voice of Jade" tone presets: Secluded Valley, Old Temple, Snowy Night.
