Verbal Analysis: The "Boris - Vomitself tuning" is an extreme and highly unconventional tuning specifically used for the track "Vomitself" by the Japanese experimental metal band Boris. This immediately signals a tuning designed for massive, resonant, and often dissonant soundscapes, characteristic of drone and doom metal genres.

Upon an open strum, this tuning produces a thick, dissonant cluster rather than a harmonious chord. The incredibly low E1 on the 6th string, an entire octave below the standard low E (E2), sets a foundation of immense depth, perfect for generating powerful, rumbling drones and heavily distorted riffs. The overall sound is dark, sprawling, and not intended for conventional melodic playing. It encourages unique textural exploration, single-note motifs, or two-note shapes over traditional chord voicings. The wide pitch range across the strings, combined with irregular intervals, makes standard chord shapes virtually impossible.

While traditional chords are largely out of reach, the presence of consecutive perfect fourths on strings 5, 4, and 3 (D#3-G#3-C#4) allows for easy two-finger power chord shapes across these specific strings, offering some structural familiarity within the chaos. However, the extreme drop in pitch for all strings, particularly the monumental -12 semitone drop on the 6th string, strongly suggests the necessity of much thicker gauge strings to maintain tension and intonation, and to avoid string floppiness.

Technical Analysis: This is a highly altered tuning for a 6-string Guitar. The tuning notes, from lowest to highest string, are:

• String 6: E1
• String 5: D3# (Eb3)
• String 4: G3# (Ab3)
• String 3: C4# (Db4)
• String 2: F3
• String 1: A4# (Bb4)

The absolute pitch range spans over three octaves, from E1 to A#4. Analyzing the intervals between adjacent strings (from low E string up):

• String 6 (E1) to String 5 (D#3): A massive Major 17th (2 octaves + Major 7th, 35 semitones) – a huge leap.
• String 5 (D#3) to String 4 (G#3): Perfect 4th (5 semitones).
• String 4 (G#3) to String 3 (C#4): Perfect 4th (5 semitones).
• String 3 (C#4) to String 2 (F3): Descending Perfect 5th (7 semitones down). Note that String 2 is pitched lower than String 3, which is highly unusual.
• String 2 (F3) to String 1 (A#4): Augmented 11th (1 octave + Augmented 4th, 17 semitones).

This highly asymmetric and wide-ranging interval structure means the tuning is not based on a traditional chord or melodic scale. The juxtaposition of a deep E1, a descending interval from String 3 to String 2, and large upward leaps creates a unique sonic landscape, ideal for experimental and heavy music where dissonance and texture are paramount.

Tuning Notes:

The final open notes for your guitar should be:

• String 6 (Low E): E1
• String 5 (A): D3#
• String 4 (D): G3#
• String 3 (G): C4#
• String 2 (B): F3
• String 1 (High E): A4#

How to Tune:

To achieve the "Boris - Vomitself tuning" from standard EADGBe tuning, follow these instructions. Please be aware that all strings require significant tuning down. For movements exceeding 4 semitones up or down, a different string gauge is highly recommended to ensure proper tension and intonation, and to prevent damage to your instrument.

• String 6 (Low E): Tune down 12 semitones to E1. This is a full octave drop. A much thicker gauge string is advised.
• String 5 (A): Tune down 6 semitones to D3#. A thicker gauge string is advised.
• String 4 (D): Tune down 6 semitones to G3#. A thicker gauge string is advised.
• String 3 (G): Tune down 6 semitones to C4#. A thicker gauge string is advised.
• String 2 (B): Tune down 6 semitones to F3. A thicker gauge string is advised.
• String 1 (High E): Tune down 6 semitones to A4#. A thicker gauge string is advised.
