Verbal and Technical Analysis

This is an intriguing "Open C" tuning, explicitly named "open c bon iver", and famously associated with the unique sound of Bon Iver, particularly for tracks like "Skinny Love". On a technical level, the open strings of this Guitar tuning resolve to the notes C2-G2-E2-G3-C4-C4 (from lowest to highest string). When strummed open, these notes collectively form a robust C Major chord (C-E-G), making it an "Open C" tuning.

The configuration features a powerful low C, a perfect fifth (G), a major third (E), followed by an octave and a half higher G, and then two high C notes. This arrangement provides a rich, resonant sound with a strong fundamental C. The repeated C and G notes across different octaves contribute to a full, harmonically rich texture. Guitarists will find this tuning conducive to creating expansive soundscapes and folk-inspired melodies.

The close proximity of the 2nd and 1st strings to C4 and C4, respectively, creates a unison effect, which can be used for drones or ringing out. The interval between the 3rd and 2nd strings (G3 to C4) is a perfect fourth, while the 4th to 3rd string (E2 to G3) is a minor third, suggesting interesting melodic and harmonic possibilities within the middle register. Chords like C major (of course, by barring), G major, F major, and A minor often become accessible with simplified fingerings due to the open C foundation, allowing for melodic exploration without complex fretting. Barre chords across certain frets will immediately yield major or minor chords, shifting the entire tonal center.

How to Tune

Achieving this "open c bon iver" tuning requires specific adjustments. Please follow the instructions below carefully for each string. Remember to proceed slowly and use a reliable tuner to reach the target notes.

• 6th String (Target: C2): Tune up 1 semitones.
• 5th String (Target: G2): Tune up 3 semitones.
• 4th String (Target: E2): Tune down 5 semitones. For this significant drop, consider using a thicker gauge string to maintain proper tension and tone.
• 3rd String (Target: G3): Tune up 5 semitones. For this significant increase in pitch, a lighter gauge string is advised to prevent excessive tension and potential string breakage.
• 2nd String (Target: C4): Tune up 5 semitones. For this significant increase in pitch, a lighter gauge string is advised to prevent excessive tension and potential string breakage.
• 1st String (Target: C4): Tune down 4 semitones.

Please note: The provided tuning movements are specific instructions. Always tune cautiously, especially when making large pitch changes. If you are unsure, consult a professional.
