FCFACGCE Open Fmaj9 8 String Tuning, Rob Scallon. - Guitar tuning, chords & scales
This 8-string guitar tuning, famously used by Rob Scallon in tracks like "Anchor," "Homehomehome," "Theater Girl," and "8 String + Loop Pedal," offers a rich and expansive sonic palette.
Verbal Analysis
True to its name, the Open Fmaj9 tuning provides a massive, resonant chord when played open. The arrangement of notes across eight strings creates an immediate sense of grandeur and harmonic complexity. It's a tuning that lends itself to atmospheric soundscapes, intricate fingerstyle, and heavy, melodic riffs, characteristic of Rob Scallon's innovative style. The extended low range of the 8-string combined with the open Fmaj9 voicings allows for deep, organ-like drones and sparkling upper harmonics, giving the instrument a full, orchestral feel, ideal for both rhythm and lead applications.
Technical Analysis
The open strings are tuned to F1-C2-F2-A2-C3-G3-C4-E4 (from lowest to highest). Analyzing these notes reveals the foundation of an Fmaj9 chord extended across the entire range of the 8-string instrument:
- F (Root): Present on strings 8 (F1) and 6 (F2). These provide a powerful fundamental and octave drone.
- A (Major 3rd): Found on string 5 (A2), establishing the major tonality.
- C (Perfect 5th): Repeated on strings 7 (C2), 4 (C3), and 2 (C4). The abundance of the fifth offers strong harmonic support and a broad resonance.
- G (Major 9th): On string 3 (G3), adding a sophisticated, jazz-influenced extension to the chord.
- E (Major 7th): On string 1 (E4), completing the dominant seventh quality and giving the chord its lush character.
How to Tune
To achieve the Open Fmaj9 tuning, adjust your 8-string guitar as follows:
- String 8 (lowest): To achieve F1, tune down 1 semitone.
- String 7: To achieve C2, tune up 1 semitone.
- String 6: To achieve F2, tune up 1 semitone.
- String 5: To achieve A2, keep as is; no change (0 semitones).
- String 4: To achieve C3, tune down 2 semitones.
- String 3: To achieve G3, keep as is; no change (0 semitones).
- String 2: To achieve C4, tune up 1 semitone.
- String 1 (highest): To achieve E4, keep as is; no change (0 semitones).
While no extreme string tension changes are required for this tuning, always pay attention to your guitar's intonation and string tension after any tuning adjustments.
