How to Tune to Open B Tuning
A massive open B major tuning (B-F#-B-F#-B-D#) that Devin Townsend uses to build his signature wall of sound. Every open string belongs to a B major chord, and the very low B gives an enormous, chiming foundation for layered ambient guitar. Strumming open produces a huge, ringing B major that suits Townsend's cinematic, reverb-drenched productions.
| String | Note | Frequency |
|---|---|---|
| String 6 | B1 | 61.74 Hz |
| String 5 | F#2 | 92.50 Hz |
| String 4 | B2 | 123.47 Hz |
| String 3 | F#3 | 185.00 Hz |
| String 2 | B3 | 246.94 Hz |
| String 1 | D#4 | 311.13 Hz |
Fun Fact
Devin Townsend layers dozens of guitar tracks in open tunings like this to create his trademark 'wall of sound.' Because every open string is part of the chord, he can stack shimmering, capoed and harmonic-laden parts that all lock together into one gigantic, choir-like texture.
String Tension & Setup Tips
Recommended Gauge:Heavy strings (.011-.056 or a baritone set) are important because the low string drops all the way to B, well below standard. Extra mass keeps the low B and F# tight and defined rather than floppy.
Frequently Asked Questions
What is Open B tuning?
Open B (B-F#-B-F#-B-D#) tunes all six strings to notes of a B major chord, so strumming the open strings sounds a full, low B major. It is essentially Open E or Open D shifted down to a deep, heavy register.
How do I tune to Open B?
This is a big detune from standard — the low E drops to B, and most strings move down substantially. Use heavier strings and tune slowly: B-F#-B-F#-B-D#. The tuner above will help you reach each low target.
Who uses Open B tuning?
Devin Townsend is closely associated with low open tunings like this for his ambient, wall-of-sound style. The deep open B major is ideal for layered, atmospheric rhythm and lead work.
