The "nandemoniya" tuning is a unique and highly expressive setup for the guitar, specifically designed for the song of the same name, as found in a YouTube tab. It moves far beyond standard tuning, offering a fresh sonic palette ideal for intricate melodic lines and atmospheric soundscapes.

Technical Analysis:

This tuning presents an intriguing and somewhat complex structure. The open strings are tuned to: D#3 - A#3 - F#4 - C#4 - G#4 - D#5 (from the lowest pitch String 6 to the highest pitch String 1). A key feature of this tuning is its re-entrant nature, where the 3rd string (C#4) is tuned lower in pitch than the 4th string (F#4). This creates unexpected harmonic possibilities and requires a re-thinking of traditional fretboard navigation.

Analyzing the intervals between adjacent strings reveals a mix of perfect fifths and other intervals:

• String 6 (D#3) to String 5 (A#3): Perfect 5th (7 semitones)
• String 5 (A#3) to String 4 (F#4): Minor 6th (8 semitones)
• String 4 (F#4) to String 3 (C#4): Descending Perfect 4th (5 semitones down)
• String 3 (C#4) to String 2 (G#4): Perfect 5th (7 semitones)
• String 2 (G#4) to String 1 (D#5): Perfect 5th (7 semitones)

The open string notes themselves (D#3, A#3, F#4, C#4, G#4, D#5) form a rich harmony. If we order them chromatically and consider D# as the root, the notes are D#, F#, G#, A#, C#, D#. This structure closely resembles a D# minor 7 (add11) chord, providing a dark, suspended, and harmonically sophisticated foundation. The repeated Perfect 5th intervals on the lower two and upper three strings will naturally facilitate power chords, drone notes, and specific arpeggio patterns within those groups.

Chordal Opportunities:

With the open strings resonating as D#m7(add11), strumming all open strings will yield a complex yet coherent minor chord. This open voicing is immediately evocative and melancholic. The re-entrant 3rd string significantly alters traditional chord shapes, encouraging players to explore new fingerings and inversions, potentially uncovering unique voicings and melodic ideas that are impossible in standard tuning. Chords based around D# minor and its related modes will likely feel natural, and the presence of the C# (minor 7th) and G# (11th) suggests a bluesy or jazzy sensibility when explored creatively, offering depth and color for intricate compositions.

This tuning is an excellent choice for players looking to break away from conventional sounds and explore new sonic territories, especially for expressive fingerstyle or ambient playing.

Open String Notes:

• String 6 (Low E String): D#3
• String 5 (A String): A#3
• String 4 (D String): F#4
• String 3 (G String): C#4
• String 2 (B String): G#4
• String 1 (High E String): D#5

How to Tune:

To achieve the "nandemoniya" tuning from standard EADGBe, follow these string-by-string adjustments:

• String 6 (Low E String): Tune down 1 semitones from its standard E pitch to reach D#3.
• String 5 (A String): Tune up 1 semitones from its standard A pitch to reach A#3.
• String 4 (D String): Tune up 4 semitones from its standard D pitch to reach F#4. Caution: Tuning up 4 semitones is a significant adjustment. For permanent use, a lighter gauge string is often advised to prevent excessive tension.
• String 3 (G String): Tune down 6 semitones from its standard G pitch to reach C#4. Warning: Tuning down 6 semitones is a very large adjustment. To maintain proper string tension, tone, and prevent buzzing, a different gauge string (likely heavier) is typically required.
• String 2 (B String): Tune down 3 semitones from its standard B pitch to reach G#4.
• String 1 (High E String): Tune down 1 semitones from its standard E pitch to reach D#5.

Always tune carefully and check string tension, especially with larger movements, to prevent string breakage or potential damage to your instrument.
