This unique 8-string Guitar tuning, which we've named Deathcore Doom Drop B 8-String, is meticulously crafted for the crushing soundscapes of Deathcore and Funeral Doom. As described, it builds upon a D Standard foundation for the higher strings, incorporates a "Drop C" characteristic (likely referring to the 4th string), and plunges the lowest string down to a formidable B, creating an exceptionally heavy and guttural sonic canvas.

Technical Analysis

The open strings are tuned as B1 C2 D2 G2 C3 F3 A3 D4 from the lowest (8th) to the highest (1st) string. This tuning features:

• Extreme Low End: The B1 on the 8th string and C2 on the 7th string provide an incredibly deep and resonant foundation, perfect for extended-range riffing and earth-shattering chugs.
• Dissonant Core: The lowest three strings (B1, C2, D2) form a tight, dissonant cluster. This close voicing is ideal for creating a menacing, atmospheric drone or incredibly dense power chords with an added minor 2nd, a hallmark of extreme metal genres.
• Familiar Power Chord Shapes: The string relationships from the 6th string upwards (D2 G2 C3 F3 A3 D4) largely preserve the perfect fourth intervals commonly found in standard guitar tuning (with the exception of the G-C-F-A interval, where F to A is a Major 3rd). This allows for easier adaptation of standard power chord shapes for heavy, rhythmic playing, particularly across the D2-G2-C3 (strings 6-5-4) and G2-C3-F3 (strings 5-4-3) groups.
• Harmonic Flexibility: While inherently dark, the tuning also offers interesting harmonic possibilities. For instance, the combination of C3, F3, and A3 (strings 4, 3, 2) forms an F Major triad (in second inversion), opening up avenues for melodic phrases or even brighter, contrasting voicings to cut through the extreme low end. Including the D4 on the 1st string creates richer extensions such as an Fmaj6 or Dm(add9) voicing, adding complexity to chordal passages.

Overall, this tuning is a powerful tool for musicians pushing the boundaries of heavy music, demanding both crushing impact and nuanced harmonic exploration across an 8-string instrument.

Open String Notes:

• String 8 (lowest): B1

How to Tune:

To achieve the Deathcore Doom Drop B 8-String tuning, follow these precise adjustments from your current tuning:

• String 8: Tune up 5 semitones to reach B1.
  Note: Tuning up by 5 semitones is a significant change. It is highly recommended to use a heavier gauge string for the 8th string to prevent breakage and ensure optimal tone and tension.
• String 7: Tune up 1 semitone to reach C2.
• String 6: Tune down 2 semitones to reach D2.
• String 5: Tune down 2 semitones to reach G2.
• String 4: Tune down 2 semitones to reach C3.
• String 3: Tune down 2 semitones to reach F3.
• String 2: Tune down 2 semitones to reach A3.
• String 1: Tune down 2 semitones to reach D4.
