This is a truly unique and deeply resonant tuning, specifically crafted to evoke the powerful, atmospheric sound of a pipe organ. It draws direct inspiration from Hans Zimmer's iconic "Davy Jones" theme, aiming to emulate its characteristic dark and brooding soundscape. The extreme low tuning transforms the guitar into a sonic landscape of immense depth, perfect for cinematic scores, ambient soundscapes, or heavy, downtempo genres. The deep F foundation provides an immense gravitational pull, offering a rich, sustained drone quality that will resonate profoundly.

Technical Analysis:

This tuning, set for a Guitar, establishes its fundamental at a remarkably low F1 on the 6th string. The full open string voicing is F1-C2-F2-A#3-D#4-G#4. Analyzing these notes reveals a complex and rich harmonic structure. The foundation F1-C2-F2 provides a strong F power chord across the lowest strings, establishing a clear root and fifth.

The subsequent notes, A#3 (Bb3), D#4 (Eb4), and G#4 (Ab4), build upon this to form a dense F minor 7 (F-Ab-C-Eb) with an added suspended 4th (Bb). This results in an incredibly full and resonant open chord that, when strummed, delivers a profound, organ-like drone. Due to the extreme down-tuning, traditional open major or minor chords will require significant re-fingering. However, this tuning excels at:

• Deep F Power Chords: Easily accessible across the lower strings (e.g., F1-C2-F2 on strings 6, 5, 4).
• Drones and Sustained Chords: The open string resonance is exceptional for sustained, ambient textures, aligning perfectly with the organ emulation goal.
• Minor and Suspended Voicings: The inherent F minor 7 sus4 quality of the open strings makes it easy to construct dark, moody harmonies by barring or simple two-finger shapes.
• Open F Minor 7sus4: The open strings themselves form a complete and usable chord for immediate harmonic impact, providing a rich, complex sonority ideal for cinematic moods.

Important Note on String Gauge:

All strings in this tuning are significantly downtuned (between 8 and 11 semitones). This degree of tuning change is substantial, and it is strongly recommended to use a much heavier gauge of strings than standard to maintain adequate tension, intonation, and prevent string flop or breakage. If you exceed 4 semitones up or 4 semitones down from standard, a different gauge string is generally advised. This tuning far exceeds that threshold, making heavier strings essential.

How to Tune from Standard EADGBE:

6th String (Low E): Tune down 11 semitones from its standard E2 note to F1.

5th String (A): Tune down 9 semitones from its standard A2 note to C2.

4th String (D): Tune down 9 semitones from its standard D3 note to F2.

3rd String (G): Tune down 9 semitones from its standard G3 note to A#3.

2nd String (B): Tune down 8 semitones from its standard B3 note to D#4.

1st String (High E): Tune down 8 semitones from its standard E4 note to G#4.
