Verbal Analysis

While the initial naming for this tuning was provided as 'fadgce capo7', the actual open notes of the guitar are C E A D G B. This unique tuning provides a deep and resonant sonic foundation, setting it apart significantly from standard EADGBe tuning. The lowest string is tuned down to C, creating a powerful bass register that lends itself to a full, rich sound. The combination of open notes—C, E, A, D, G, B—forms a complex harmony that isn't immediately an open major or minor chord, but offers a versatile palette for creative songwriting across various genres, from folk and fingerstyle to more experimental soundscapes. The overall significant downtuning across most strings means the string tension will be considerably lower than in standard tuning, which might make playing easier for some, but could also benefit from a heavier string gauge to maintain clarity and avoid fret buzz, especially if played aggressively.

Technical Analysis

Intervalic Structure:

• String 6 (C2) to String 5 (E2): A Major 3rd interval.
• String 5 (E2) to String 4 (A2): A Perfect 4th interval.
• String 4 (A2) to String 3 (D3): A Perfect 4th interval.
• String 3 (D3) to String 2 (G3): A Perfect 4th interval.
• String 2 (G3) to String 1 (B3): A Major 3rd interval.

This distinct pattern of two major thirds bracketing three consecutive perfect fourths (C-E | E-A-D-G | G-B) creates a unique sonic signature, offering both stable harmonic anchors and open, ringing fourths.

Open Chord Possibilities:

• C Major (implied Cmaj7/9): With C (string 6), E (string 5), G (string 2), and B (string 1), an open C Major chord with extended harmonies is very accessible. Playing strings 6, 5, 2, 1 offers C-E-G-B, a Cmaj7.
• A Minor: The notes A (string 4), C (string 6), and E (string 5) are all present. An open A minor triad (A-C-E) is easily formed. Strumming strings 6, 5, 4 (C-E-A) creates an A minor second inversion.
• G Major (implied Gmaj7/9): The notes G (string 2), B (string 1), and D (string 3) are available. Playing strings 3, 2, 1 (D-G-B) forms a G major chord with a D in the bass, which is very common.
• D Sus4/Sus2: D (string 3), G (string 2), and A (string 4) are present, allowing for easy open Dsus4 (D-G-A) or Dsus2 (D-E-A, by fretting string 5 at 2nd fret for E) voicings.

Fretboard Navigation:

The series of three perfect fourths in the middle strings (E-A-D-G on strings 5-2) can make some familiar patterns from the lower strings of standard tuning transferable. However, the significantly altered low C and high B strings will necessitate adapting traditional chord shapes and scale patterns, encouraging exploration and discovery of new voicings unique to this tuning. The overall low pitch creates a deeper, darker timbre suitable for powerful accompaniment or intricate melodic work.

How to Tune: Open C E A D G B Tuning

To achieve the Open C E A D G B Tuning from standard EADGBe, follow these string-by-string instructions. Please be aware that several strings require significant downward tuning. For any string movement exceeding 4 semitones down or up, it is generally recommended to consider using a different string gauge to maintain optimal string tension, intonation, and playability, as well as to prevent string breakage or damage.

For reference, standard tuning notes are E2 A2 D3 G3 B3 E4.

• String 6 (Lowest String): Start from E2. Tune down 4 semitones to reach C2.
• String 5: Start from A2. Tune down 5 semitones to reach E2.
  Caution: This is a substantial drop. If you plan to use this tuning frequently, a heavier gauge string is advised for this string.
• String 4: Start from D3. Tune down 5 semitones to reach A2.
  Caution: This is a substantial drop. If you plan to use this tuning frequently, a heavier gauge string is advised for this string.
• String 3: Start from G3. Tune down 5 semitones to reach D3.
  Caution: This is a substantial drop. If you plan to use this tuning frequently, a heavier gauge string is advised for this string.
• String 2: Start from B3. Tune down 4 semitones to reach G3.
• String 1 (Highest String): Start from E4. Tune down 5 semitones to reach B3.
  Caution: This is a substantial drop. If you plan to use this tuning frequently, a heavier gauge string is advised for this string.
