Verbal Analysis

TK's Seacret D# Octave Jump is an exceptionally unique and avant-garde guitar tuning, famously employed by TK from the Japanese band Ling Tosite Sigure, particularly for tracks like 'Seacret CM'. This setup fundamentally redefines the guitar's sonic capabilities, creating a landscape that is both profoundly dark and intensely bright. It masterfully combines deep, resonant bass notes with incredibly high, shimmering trebles, resulting in an extraordinary dynamic and pitch range. This tuning challenges traditional playing techniques and encourages the guitarist to explore unconventional harmonies, dissonant textures, and intricate, wide-ranging arpeggios that are simply not achievable in standard tunings. It's a tuning for those seeking to break free from conventional chord shapes and embrace a highly experimental and expressive approach to the instrument.

Technical Analysis

The open string configuration for this tuning is D#3 A#3 F3 C#5 G#4 D#5, ordered from the 6th (lowest) to the 1st (highest) string. The tuning establishes a powerful D# root, providing a deep, heavy foundation. The interval structure is highly unconventional: the 5th string (A#3) is a perfect fifth above the 6th (D#3), but notably, the 4th string (F3) is a major second above the 6th, placing it lower in pitch than the 5th string. This non-linear arrangement creates fascinating melodic possibilities and unique open string voicings. The most striking feature is the extreme pitch of the 3rd string, C#5, which is two octaves higher than a typical G3 in standard tuning. This piercing note, along with the high G#4 (2nd string) and D#5 (1st string), creates a vast intervallic spread across the neck, extending the guitar's upper register dramatically. Open chords formed by these strings are far from traditional; the open notes collectively suggest a complex D#sus2-like voicing with added tensions (Root, Major 2nd, Perfect 4th, Perfect 5th, minor 7th, Octave), indicating an emphasis on specific melodic lines, open drones, and arpeggiated figures rather than simple strummed chords. Despite its complexity, open D#5 power chords (D#3, A#3) remain readily available on the lowest two strings.

How to Tune

To achieve TK's Seacret D# Octave Jump tuning, assuming an unspecified starting point, follow these precise instructions for each string:

• 6th String (Low E equivalent): Tune down 1 semitone to D#3.
• 5th String (A equivalent): Tune up 1 semitone to A#3.
• 4th String (D equivalent): Tune up 3 semitones to F3.
• 3rd String (G equivalent): Tune up 6 semitones to C#5. Caution: Tuning up 6 semitones places extreme tension on the string. A significantly lighter gauge string is strongly advised to prevent breakage or potential damage to your instrument's neck.
• 2nd String (B equivalent): Tune down 3 semitones to G#4.
• 1st String (High E equivalent): Tune down 1 semitone to D#5.

For any string movements exceeding 4 semitones (either up or down), it is generally recommended to consider using a different gauge string to ensure optimal playability and to safeguard against potential damage to your instrument due to excessive or insufficient tension.

6th String: D3# (The lowest string, providing a deep, resonant foundation for the tuning.)

5th String: A3# (A perfect fifth above the 6th string, adding depth and power to the bass register.)

4th String: F3 (A major second above the 6th string, creating an unusual, non-linear interval relative to the 5th string.)

3rd String: C5# (An exceptionally high note, two octaves above its standard equivalent, designed for piercing melodies and unique textures. Extreme caution is advised when tuning this string due to high tension.)

2nd String: G4# (A high pitch that complements the upper register, though less extreme than the 3rd string, contributing to the wide tonal range.)

1st String: D5# (The highest string, an octave above the low D# on the 6th string, completing the vast dynamic and pitch spread of this unique tuning.)
