How to Tune to C6 Tuning (CACGCE)
The C6 tuning (C-A-C-G-C-E) Jimmy Page used for Led Zeppelin's acoustic instrumental "Bron-Yr-Aur" and the funky "Friends." Strumming the open strings gives a C major sixth chord — bright, folky and slightly jazzy. The tuning's stacked C notes and open A give it a distinctive ringing, harp-like quality perfect for cascading fingerpicked lines.
| String | Note | Frequency |
|---|---|---|
| String 6 | C2 | 65.41 Hz |
| String 5 | A2 | 110.00 Hz |
| String 4 | C3 | 130.81 Hz |
| String 3 | G3 | 196.00 Hz |
| String 2 | C4 | 261.63 Hz |
| String 1 | E4 | 329.63 Hz |
Fun Fact
"Bron-Yr-Aur" is named after the 18th-century cottage in Wales where Robert Plant and Jimmy Page retreated in 1970 to write much of Led Zeppelin III. Page composed the delicate solo-guitar piece in this C6 tuning; it was recorded then, but not released until Physical Graffiti in 1975.
String Tension & Setup Tips
Recommended Gauge:Medium acoustic gauges (.012-.054) are ideal. The low E drops to C so a heavier 6th string helps; the high E drops to E only relative to... it stays E, and the B raises to C (a half step, safe). Overall tension is slightly below standard.
Frequently Asked Questions
What tuning is Bron-Yr-Aur by Led Zeppelin in?
"Bron-Yr-Aur" uses C6 tuning: C-A-C-G-C-E (low to high). Jimmy Page fingerpicks the entire piece in this tuning, using the open strings as drones under a moving melody. Note this is different from the electric "Bron-Y-Aur Stomp."
How do I tune to C6 (CACGCE)?
From standard: drop the low E two whole steps to C, drop the A... keep A, drop the D a whole step to C, keep G, raise the B a half step to C, keep the high E. So only three strings move: E→C, D→C, B→C. Use the tuner above to confirm.
Is Friends by Led Zeppelin the same tuning?
Yes — "Friends" from Led Zeppelin III uses the same C6 tuning. Its aggressive, orchestrated acoustic riff shows the tuning's heavier side, while "Bron-Yr-Aur" shows its delicate, melodic side.
