The All F Unison Tuning is an extremely unique and experimental guitar tuning where every open string resonates with the note F, across various octaves. This creates a powerful, resonant, and almost drone-like sound when strummed openly, providing a rich, full-bodied F Major sonority without any fretting.

Verbal Analysis

This tuning transforms the guitar into a monophonic F instrument, perfect for composers and players looking to explore ambient soundscapes, experimental music, or pieces that center around a strong F tonic. The pervasive F note across all strings lends itself well to drone-based music, creating a dense harmonic foundation. While traditional chord shapes will be completely redefined, this tuning encourages new ways of thinking about harmony and melody, making it an excellent playground for slide guitarists or those keen on percussive and textural playing.

Technical Analysis

• Open Chords: The open tuning itself is a massive F Major chord, featuring multiple Fs across different octaves (F2, F2, F3, F3, F4, F4). This means that simply strumming the open strings will produce a full and commanding F Major sound.
• Chord Shapes & Intervals: The distinct pattern of Unison-Octave-Unison-Octave-Unison between adjacent strings (F2-F2, F2-F3, F3-F3, F3-F4, F4-F4) simplifies playing across octaves and creates rich, dense textures. Barre chords become powerful unison chords, where a single finger across a fret produces that specific note across multiple octaves (e.g., barring at the 5th fret yields all 'A' notes). This tuning is fantastic for creating massive sounding power chords or drones with minimal effort.
• Potential: Its uniformity makes it ideal for exploring modal music built around F, creating hypnotic ostinatos, or generating a wall of sound. Slide playing would be particularly effective, allowing smooth transitions through unison tones.

How to Tune

Please exercise caution, particularly with significant string tension changes. For movements exceeding 4 semitones in either direction, it is highly recommended to consider using a different string gauge to prevent string breakage and potential damage to your instrument's neck.

• 6th String (Low E): Tune up 1 semitone from E2 to F2.
• 5th String (A): Tune down 4 semitones from A2 to F2. (Note: Tuning down 4 semitones is a significant drop; monitor string tension and consider a different gauge string.)
• 4th String (D): Tune up 3 semitones from D3 to F3. (Note: Tuning up 3 semitones is a notable increase; monitor string tension and consider a different gauge string.)
• 3rd String (G): Tune down 2 semitones from G3 to F3.
• 2nd String (B): Tune up 6 semitones from B3 to F4. (Extreme Caution: Tuning up 6 semitones is a very drastic increase. A much lighter gauge string for this position is strongly advised to prevent string breakage and potential neck damage.)
• 1st String (High E): Tune up 1 semitone from E4 to F4.
