This is an incredibly deep and resonant 8-string guitar tuning, aptly named "Bmaj w/ relative G#min" by its creator, who notes the use of bass strings to achieve its extreme low range. Starting with an unprecedented B0 on the lowest string, this tuning delves into a sonic landscape typically reserved for bass guitars or dedicated extended-range instruments, offering a massive, foundational sound.

Technically, the open string notes are B0-F#2-B1-F#3-G#3-D#4-F#4-B3. This arrangement immediately establishes a strong B major tonality, incorporating the root (B), perfect fifth (F#), and major third (D#). The inclusion of G# further expands the harmonic possibilities, allowing for both B Major 6 (B-D#-F#-G#) and its relative minor, G# minor (G#-B-D#), to be readily available in open position. The multiple octaves of B and F# across the strings create a powerful drone effect, adding immense depth and sustain to any chord or riff.

The wide intervallic jumps, such as the 14 semitones between B0 and F#2, or the 17 semitones between B1 and G#3, create a truly unique harmonic spread. Open chords ring out with a full, orchestral quality, making this tuning ideal for heavy metal, djent, ambient soundscapes, or any genre requiring a vast and imposing sonic palette. Players will find open B major chords and G# minor chords to be particularly rich and easy to access, along with power chords based on B and F# on the lower strings. The structure also lends itself well to melodic ideas that exploit the natural harmony of B major and G# minor.

Open String Notes:

• String 8: B0 (Lowest string)
• String 7: F#2
• String 6: B1
• String 5: F#3
• String 4: G#3
• String 3: D#4
• String 2: F#4
• String 1: B3 (Highest string)

How to Tune:

This tuning involves significant drops for all strings. When tuning down 4 semitones or more, a heavier gauge string is strongly advised to maintain tension and optimal tone.

• String 8 (B0): Tune down 7 semitones from its standard E2. (Heavier gauge strongly advised)
• String 7 (F#2): Tune down 5 semitones from its standard A2. (Heavier gauge strongly advised)
• String 6 (B1): Tune down 5 semitones from its standard D3. (Heavier gauge strongly advised)
• String 5 (F#3): Tune down 3 semitones from its standard G3. (Consider a heavier gauge)
• String 4 (G#3): Tune down 6 semitones from its standard B3. (Heavier gauge strongly advised)
• String 3 (D#4): Tune down 4 semitones from its standard E4. (Heavier gauge strongly advised)
• String 2 (F#4): Tune down 5 semitones from its standard B4. (Heavier gauge strongly advised)
• String 1 (B3): Tune down 5 semitones from its standard E5. (Heavier gauge strongly advised)
