Verbal Analysis: The "Deadnest Monuments" tuning is an expansive 8-string guitar setup, clearly designed for the sonically demanding landscapes of modern progressive and technical metal, heavily influenced by the band Monuments. With its extraordinarily low F0 on the 8th string, this tuning delves into frequencies typically reserved for bass guitars, providing a colossal foundation for crushing riffs and deeply resonant soundscapes. The interplay of F, A# (which can be interpreted as Bb), and D# (Eb) across the strings suggests a harmonic palette that is both heavy and complex, allowing for dissonant textures alongside powerful, open-string chugging.

Technical Analysis:

• Instrument Type: This tuning is specifically crafted for an 8-string Guitar, leveraging its extended range to achieve the signature deep resonance and wide melodic possibilities.
• Open Tuning Notes: The open strings are tuned to F0, A#2, F2, A#3, D#4, F3, A#4, D#5. When ordered by pitch from lowest to highest, the notes are F0, F2, A#2 (Bb2), F3, A#3 (Bb3), D#4 (Eb4), A#4 (Bb4), D#5 (Eb5).
• Harmonic Characteristics: The open strings reveal a rich, complex sonority. The primary notes are F, A# (Bb), and D# (Eb). This combination forms an open Fsus4(add6) or Fsus4(add b7) chord (F - Root, A# - Perfect 4th, D# - Minor 7th). It can also be perceived as an Eb Major triad (Eb, G, Bb) with an F in the bass, or a Bb Major 7th chord with a missing 3rd (D). This implies a dark, modal sound, characteristic of contemporary progressive metal, suitable for intricate arrangements and powerful, low-end driven passages.
• Chords and Playability: The prevalence of Fs, A#s, and D#s across the open strings allows for massive, resonant power chords and sustained drones. Single-finger barres across the lower strings will naturally yield powerful F, A#, or D# based chords. The tuning facilitates easy access to very low, heavy riffs, particularly those centered around F. The repeated octaves (F octaves across strings 8, 6, 3; A# octaves across strings 7, 5, 2; D# octaves across strings 4, 1) simplify chord shapes and lead lines, making complex voicings more approachable within this specific harmonic framework. The exceptionally wide interval between the 8th (F0) and 7th (A#2) string (29 semitones) means that traditional chord shapes will require significant adaptation to span such a vast range.

Open String Notes:

• String 8 (Low F): F0
• String 7 (A#): A#2
• String 6 (F): F2
• String 5 (A#): A#3
• String 4 (D#): D#4
• String 3 (F): F3
• String 2 (A#): A#4
• String 1 (High D#): D#5

How to Tune:

Please proceed with caution, especially for strings requiring significant tension changes. Generally, tuning up or down 3 or 4 semitones requires care. If a string movement exceeds -4 semitones (e.g., -5, -8) or is 4 semitones or above (e.g., 4, 5, 6), a different gauge string is advised to maintain proper tension, intonation, and prevent potential string breakage or neck damage.

• String 8 (Low F): Tune down 8 semitones to F0. This is a significant drop; a heavier gauge string is strongly advised.
• String 7 (A#): Tune up 4 semitones to A#2. Exercise caution; a lighter gauge string is advised.
• String 6 (F): Tune up 6 semitones to F2. This is a very substantial increase in tension; a lighter gauge string is highly recommended.
• String 5 (A#): Tune up 6 semitones to A#3. This is a very substantial increase in tension; a lighter gauge string is highly recommended.
• String 4 (D#): Tune up 6 semitones to D#4. This is a very substantial increase in tension; a lighter gauge string is highly recommended.
• String 3 (F): Tune up 3 semitones to F3. Proceed with care.
• String 2 (A#): Tune up 3 semitones to A#4. Proceed with care.
• String 1 (High D#): Tune up 4 semitones to D#5. Exercise caution; a lighter gauge string is advised.
