This unique and powerful tuning, famously associated with Chris Cornell for 'Seasons', transforms the standard guitar into a resonant soundscape. It's built around the core notes of F and C, predominantly presenting a deep and full F5 power chord across its open strings.

Verbal Analysis

The FFCCCF tuning delivers an incredibly rich, dark, and almost orchestral sound. With two low Fs and two middle Cs, it creates a massive sonic foundation, ideal for heavy, droning riffs, percussive strumming, or introspective, brooding textures. The absence of a major or minor third (like 'A' in F major) means the tuning is inherently ambiguous and powerful, making it versatile for both heavy rock and atmospheric soundscapes. The doubled notes on the low F and middle C strings contribute to an immense sustain and thickness, allowing single notes or simple chord shapes to fill a large sonic space. This tuning would lend itself well to compositions demanding a weighty, unyielding presence, where the interplay of open strings can create a sense of vastness.

Technical Analysis

Technically, this is an open F5 power chord tuning. The notes, from low to high, are F2, F2, C3, C3, C4, F4. This consists solely of the root (F) and the perfect fifth (C) of an F major chord, spread across several octaves. The arrangement of these notes provides:

• Unison Roots: The 6th and 5th strings are both tuned to F2, creating a powerful, unison bottom end.
• Unison Fifths: The 4th and 3rd strings are both tuned to C3, reinforcing the fifth.
• Octaves: The 3rd string (C3) and 2nd string (C4) form a perfect octave, adding brightness and clarity to the fifth.
• Perfect Fourth: The top two strings, C4 and F4, form a perfect fourth, a common interval in many tunings, allowing for melodic possibilities on the higher register.

This structure means that simply strumming all open strings produces a full, resonant F5 chord, which is immensely satisfying for heavy riffing or a sustained drone. Other power chords can be easily formed by barring across frets. For example, barring at the 1st fret yields an F#5, the 3rd fret a G5, and so on. The inherent F5 structure makes complex fingerings less necessary for a full sound, encouraging exploration of rhythm and dynamics. Exploring single-string melodies or two-note harmonies on the higher strings can reveal interesting intervallic relationships within this F-C framework. Due to the extreme string movements (especially the 3rd string down 7 semitones and the 5th string down 4 semitones), players should consider using heavier gauge strings to maintain proper tension and intonation, especially on the 3rd string.

Target Notes

Here are the notes for each string in FFCCCF tuning, from the thickest (6th) to the thinnest (1st):

• 6th String (Low E string in standard tuning): F2
• 5th String (A string in standard tuning): F2
• 4th String (D string in standard tuning): C3
• 3rd String (G string in standard tuning): C3
• 2nd String (B string in standard tuning): C4
• 1st String (High e string in standard tuning): F4

How to Tune

To achieve FFCCCF tuning from standard EADGBe, follow these steps for each string:

• 6th String: Tune up 1 semitone from E to F2.
• 5th String: Tune down 4 semitones from A to F2. (Note: Tuning down 4 semitones is significant; a heavier gauge string is advised for optimal tension and playability.)
• 4th String: Tune down 2 semitones from D to C3.
• 3rd String: Tune down 7 semitones from G to C3. (Warning: Tuning down 7 semitones is an extreme change. A much heavier gauge string is strongly advised to maintain proper tension, intonation, and to prevent string floppiness.)
• 2nd String: Tune up 1 semitone from B to C4.
• 1st String: Tune up 1 semitone from e to F4.
