This is a unique and powerful 7-string guitar tuning, officially named "Drop G# Alternative tuning. DADGAD variation." and further described as a "DADGAD variation for 7 string." It delves into lower registers, emphasizing deep, resonant tones perfect for heavy genres, progressive music, or experimental soundscapes where a rich, open voice is desired.

Technical Analysis

The open strings are tuned to G#2 C#3 G#3 C#4 F#4 G#4 C#5. This tuning establishes a strong drone foundation on G# and C#, effectively creating a massive C#sus4 chord voicing across multiple octaves (C#-F#-G#). The prevalent Perfect 4th intervals between many of the strings (G#2-C#3, G#3-C#4, C#4-F#4, G#4-C#5) offer logical fretboard navigation and facilitate unique chord voicings and arpeggios, reminiscent of all-fourths tuning in places. The single Major 2nd interval between the 3rd and 2nd strings (F#4-G#4) adds a distinct color and prevents the tuning from being purely intervallic, introducing melodic tension and release points. The 'Drop G#' aspect means the lowest string is significantly lowered, providing an extended bass range for earth-shattering riffs and powerful low-end articulation, characteristic of modern metal and djent styles. The 'DADGAD variation' suggests an emphasis on open string drones and modal playability, making it surprisingly versatile for both heavy chugging and intricate fingerstyle passages.

Accessible Chords & Voicings

• C#sus4 Chord: The open strings readily form a huge C#sus4 chord (C#-F#-G#) across the neck, offering a naturally rich and suspended sound that can be easily droned.
• G# Power Chords: Given the G#-C#-G# pattern on the lowest three strings, heavy G#5 power chords are extremely accessible with minimal effort, perfect for metal and rock.
• Modal Exploration: The open, intervallic nature, similar to DADGAD, encourages modal playing and the use of open string drones under various chord shapes. This makes it suitable for creating atmospheric textures and exotic soundscapes.
• Barre Chords: The consecutive Perfect 4th intervals simplify barre chord shapes across groups of strings, allowing for easy shifting and complex harmonic structures.

How to Tune

To achieve this "Drop G# Alternate DADGAD (7-string)" tuning from standard 7-string tuning (B E A D G B E), please follow these steps carefully:

• String 7 (lowest): Tune down 3 semitones from B to G#2.
• String 6: Tune down 3 semitones from E to C#3.
• String 5: Tune down 1 semitones from A to G#3.
• String 4: Tune down 1 semitones from D to C#4.
• String 3: Tune down 1 semitones from G to F#4.
• String 2: Tune down 3 semitones from B to G#4.
• String 1 (highest): Tune down 3 semitones from E to C#5.

Please note that several strings require tuning down by 3 semitones. While generally safe, extreme changes in pitch can affect string tension and intonation. If you frequently use tunings that require movements of more than 4 semitones up or down, considering a different string gauge might be beneficial for optimal playability and string longevity.
