12 string Whole Step Tuning (Lower half)
This is a unique and specialized tuning designed for the Guitar, specifically described as the "Lower half" of a 12-string setup. It offers a departure from standard tunings, aiming for a distinct sonic palette.
Technical Analysis
The open strings are tuned to B1, C#3, D#3, F2, G2, A2 (from thickest to thinnest). While the name suggests a "whole step" characteristic, the tuning notes themselves present an interesting mix of intervals rather than a continuous whole-step scale across all strings. Notably, there are whole step intervals between the 5th and 4th strings (C#3 to D#3), and a consecutive sequence of whole steps between the 3rd, 2nd, and 1st strings (F2 to G2 to A2). The overall range spans from a very deep B1 on the 6th string to A2 on the 1st string, offering a broad spectrum with a resonant low end.
This tuning does not immediately lend itself to common open major or minor chords, which encourages exploration of more unconventional voicings. Instead, it provides a foundation for modal, atmospheric, or even dissonant harmonic structures. The deep B1 and F2 can create a powerful drone effect, while the whole-step clusters (F-G-A and C#-D#) offer distinct melodic possibilities. Players may find themselves exploring extended chords, suspended voicings, or unique melodic lines that capitalize on the specific open string relationships rather than relying on traditional chord shapes.
How to Tune
To achieve the 12 string Whole Step Tuning (Lower half), follow these precise adjustments for each string. Please note that several strings require significant tuning changes, and considering a different string gauge may be advisable for optimal tension and playability.
- 6th String (B1): Tune up 5 semitones. Warning: Tuning up 5 semitones is a significant change. A heavier gauge string is strongly advised for stability and to prevent potential string breakage or neck damage.
- 5th String (C#3): Tune up 2 semitones.
- 4th String (D#3): Tune down 1 semitone.
- 3rd String (F2): Tune down 4 semitones. Warning: Tuning down 4 semitones is a significant change. A lighter gauge string is strongly advised to maintain adequate tension and playability.
- 2nd String (G2): Tune down 7 semitones. Warning: Tuning down 7 semitones is a very significant change. A lighter gauge string is strongly advised to maintain adequate tension and playability.
- 1st String (A2): Tune down 10 semitones. Warning: Tuning down 10 semitones is an extremely significant change. A much lighter gauge string is strongly advised to maintain adequate tension and playability.
The open notes for this "12 string Whole Step Tuning (Lower half)" are:
