Verbal Analysis:

This experimental tuning, referred to by its creator as "very cool sounding," offers a unique blend of deep resonance and bright, shimmering overtones. It's built upon a solid low D foundation, providing a powerful drone, while the upper strings introduce wide, open intervals that evoke a sense of space and complexity. The exceptionally high F# on the first string gives this tuning a distinctive, almost chime-like quality, making it potentially inspiring for ambient soundscapes, intricate fingerstyle pieces, or experimental compositions where a rich, sustained harmony is desired. It encourages exploration beyond conventional chord shapes, inviting players to discover new melodic and harmonic possibilities.

Technical Analysis:

The tuning notes are D2-A2-D3-B3-E3-F#5. At its core, this tuning establishes a robust D5 power chord (D-A-D) on the lowest three strings, providing a strong, resonant bass foundation. When all open strings are played together, they form a rich D Major 6/9 chord, with the notes D (root), A (perfect 5th), D (octave), B (major 6th), E (major 9th), and F# (major 3rd, albeit two octaves higher). The high F#5 is particularly notable for its extreme pitch.

• The intervals between the strings are highly varied, creating a distinctive harmonic texture:
• String 6 to 5 (D2 to A2): Perfect 5th
• String 5 to 4 (A2 to D3): Perfect 4th
• String 4 to 3 (D3 to B3): Major 6th
• String 3 to 2 (B3 to E3): Perfect 4th
• String 2 to 1 (E3 to F#5): A remarkable Major 2nd spanning two octaves, creating a very bright and piercing top voice.

The presence of the D-A-D on the bottom strings means that traditional open D power chord shapes are readily available and provide a strong rhythmic and harmonic anchor. The B (6th) and E (9th) add color and suspension to the underlying D chord. Chords built around the low D string will benefit from its open resonance, and simple one-finger barres across the middle strings can yield interesting voicings due to the unique intervals. The extremely high F#5 string suggests a potential for soaring melodies, drone notes, or percussive accents that stand out prominently above the rest of the tuning.

Tuning Notes:

• String 6 (Low E string position): D2
• String 5 (A string position): A2
• String 4 (D string position): D3
• String 3 (G string position): B3
• String 2 (B string position): E3
• String 1 (High E string position): F#5

How to Tune:

Carefully adjust each string from standard tuning (E-A-D-G-B-E) according to the following instructions. Pay close attention to the semitone movements, especially for larger adjustments.

• String 6 (Low E): Tune down 2 semitones to D2.
• String 5 (A): Keep as is; no change (0 semitones) at A2.
• String 4 (D): Keep as is; no change (0 semitones) at D3.
• String 3 (G): Tune up 4 semitones to B3. (Caution: Tuning up 4 semitones is a significant increase in tension. Consider a lighter gauge string if this tuning is played frequently.)
• String 2 (B): Tune down 7 semitones to E3. (Caution: Tuning down 7 semitones is a substantial drop and may result in a looser string feel or potential fret buzz. A heavier gauge string might be beneficial here.)
• String 1 (High E): Tune up 2 semitones to F#5.

General Gauge Advisory: For string movements exceeding negative 4 or positive 4 semitones, it is generally advised to consider a different gauge string to maintain optimal playability, intonation, and string tension.
