The 'facfae' tuning transforms your guitar into a vibrant, resonant soundscape, specifically creating an F Major 7th chord when strummed open. This is a delightful tuning for exploring lush harmonies and open-string drones, building upon the foundational elements of a typical 'FAC' type variant but with a sophisticated seventh.

Technically, the strings are tuned from low to high as F2-A2-C3-F3-A3-E4. This arrangement provides the root (F), major third (A), perfect fifth (C), and major seventh (E) of an F major 7th chord. The root, major third, and perfect fifth are doubled across different octaves (F2/F3, A2/A3, C3), creating a full and rich harmonic foundation. The highest string, E4, acts as the major seventh, adding a bright and articulate top end to the chord.

This tuning is an excellent choice for guitarists seeking an expansive, open sound, particularly suited for fingerstyle playing, ambient textures, or songwriting that benefits from readily available sophisticated voicings. The inherent Fmaj7 chord allows for easy access to beautiful jazz, folk, and contemporary harmonies. One of the significant advantages is the simplification of barre chords: by barring all six strings at any fret, you instantly achieve a Major 7th chord. For example, barring at the 1st fret yields an F#maj7, at the 2nd fret a Gmaj7, and so on. The strategic presence of the high E string as the major seventh provides a shimmering quality, perfect for melodic lines or expressive chord extensions over the open drone.

Tuning Notes:

• String 6 (Low E): F2
• String 5 (A): A2
• String 4 (D): C3
• String 3 (G): F3
• String 2 (B): A3
• String 1 (High E): E4

How to Tune:

To achieve the 'facfae' tuning from standard E Standard tuning (E-A-D-G-B-E), carefully adjust each string as follows:

• String 6 (Low E): Tune up 1 semitone to F2.
• String 5 (A): Keep as is; no change (0 semitones).
• String 4 (D): Tune down 2 semitones to C3.
• String 3 (G): Tune down 2 semitones to F3.
• String 2 (B): Tune down 2 semitones to A3.
• String 1 (High E): Keep as is; no change (0 semitones).
