In the summer of 1977, NASA prepared to launch two spacecraft beyond the solar system. Aboard each was a golden record — a message to whatever intelligence might one day find it. Among the twenty-seven pieces of music chosen to represent all of human civilization, one stood apart: Liú Shuǐ (流水, “Flowing Streams”), performed on the guqin by Guǎn Pínghú (管平湖).
This was the only Chinese music on the record. At seven minutes and thirty-seven seconds, it was the longest piece of all — longer even than Beethoven’s Fifth Symphony (7:20).
The Man Who Made the Case
When NASA’s team sought a piece of Chinese music for the Golden Record, they turned to Chou Wen-chung (周文中, 1923–2019) — composer, musicologist, and director of the Center for U.S.-China Arts Exchange at Columbia University. His answer was immediate: Flowing Streams.
The NASA team hesitated. The piece was abstract, without melody in any Western sense. It was too long. It was, they felt, something an alien civilization could not possibly understand.
Chou Wen-chung disagreed. He worked through the night, drafting a case for the selection. His argument was precise: the guqin is an instrument that has existed since the time of Confucius — the unbroken voice of a civilization spanning three thousand years. Flowing Streams is not a simple melody. It is a meditation on human consciousness and its resonance with the cosmos. And Guǎn Pínghú’s performance, with its seventy-two cascading rolls of the liú shuǐ passage, represented the absolute summit of the guqin tradition.
The three tones of the guqin — open strings, stopped strings, harmonics — produce a sound unlike any other instrument on earth. It is, Chou argued, precisely the kind of sound most likely to be understood across species and millennia: not a tune, but a texture; not a statement, but a presence.
NASA passed the selection unanimously.
The Instrument, the Player, the Piece
Guǎn Pínghú (管平湖, 1897–1967) was the foremost guqin master of the modern era — the definitive interpreter of the Sichuan school’s Flowing Streams, a tradition descending from Zhāng Kǒngshān (张孔山) through Qín Hèmíng (秦鹤鸣). His 1956 recording, made on a Tang Dynasty guqin named Qīng Yīng (清英) — an instrument already more than a thousand years old at the time — captured a performance that has never been surpassed.
Flowing Streams itself traces its origins to one of the oldest stories in Chinese musical culture: the friendship between the musician Bó Yá (伯牙) and his listener Zhōng Zǐqī (钟子期). Their bond was so complete that Bó Yá’s music needed no explanation — Zhōng Zǐqī heard mountains in the high notes, and flowing water in the low. When Zhōng Zǐqī died, Bó Yá broke his strings and never played again. There was no one left who could truly listen.
NASA sent the piece into space anyway. An act of faith that somewhere, someone — or something — might listen.
What This Means
Voyager 1 has now left the solar system entirely. It travels at roughly 17 kilometres per second. The golden record it carries will outlast every human institution, every language, every civilization on earth. In forty thousand years, it will make its closest approach to another star.
The guqin will be there.
A Tang Dynasty instrument. A twentieth-century master. A three-thousand-year tradition. Chosen, above all others, to speak for humanity.
At Seven String Qin, we carry this tradition forward. The guqin that Guǎn Pínghú played is gone beyond reach — but the lineage it represents is alive. Every instrument we make is part of that same unbroken thread.
