This is a highly experimental and deep tuning designed for a Guitar, originating from an "experimental" tuning description. The open strings, C#3, F#3, B2, F#4, B3, E4, present a truly unique soundscape, characterized by its remarkably low register and the prominent B and F# notes. The tuning drops the three lowest strings significantly, creating a dark, resonant, and almost industrial quality. The low C# provides a deep foundational bass, while the subsequent F# and an unusually low B (B2 on the 4th string!) create an intriguing, non-linear tonal progression across the lower strings.

The upper strings (F# B E) retain a more conventional perfect fourth relationship, reminiscent of some open chord tunings, but the overall structure is quite distinct and offers fresh possibilities for composition and improvisation. This tuning would be excellent for heavy, drone-like riffs, ambient soundscapes, or exploring dissonant, wide-interval voicings not typically found in standard guitar tuning. It leans towards a B minor or B suspended tonality, yet with the C# as the lowest note, it offers a unique, brooding flavor that challenges conventional harmony.

Technical Analysis

• Instrument: Guitar
• Tuning Type: This is a significantly modified drop tuning, with substantial lowering of the lowest strings. It doesn't neatly fit into common open chord categories but features a blend of perfect fourths and an unusual low B on the 4th string.
• Open Notes: The open strings are C#3, F#3, B2, F#4, B3, E4 (from low E string to high E string).
• Interval Relationships (low to high):
  • String 6 (C#3) to String 5 (F#3): Perfect Fourth (P4)
  • String 5 (F#3) to String 4 (B2): Descending Perfect Fourth + Octave Down. This creates a wide, non-linear jump and places B an octave below F#.
  • String 4 (B2) to String 3 (F#4): Compound Perfect Fifth (P12). This is a very wide ascending interval, spanning more than an octave.
  • String 3 (F#4) to String 2 (B3): Descending Perfect Fourth. Another wide interval, with B an octave below F#.
  • String 2 (B3) to String 1 (E4): Perfect Fourth (P4)
• Chordal Implications:
  • The unique open notes across the tuning are B, C#, E, F#. This collection strongly suggests a Bsus4 chord (B E F#) with an added 9th (C#).
  • Specifically, the highest three strings (F#4, B3, E4) form a clear F#sus4 voicing (F# P4 B P4 E), offering a solid foundation for melodic work.
  • The lowest three strings (C#3, F#3, B2) can be interpreted as a very wide, open voicing related to an F#sus4 inversion (F# B C#), providing a deep and resonant drone capability.
  • Due to the strong presence of B and F#, chords like Bsus4, Bsus2, or partial B minor shapes might be easily accessible and resonant across the neck, especially when incorporating the open strings.

How to Tune

To achieve this unique tuning from standard E Standard (EADGBe), follow these steps. Please exercise caution when adjusting string tension, especially for significant changes, and always ensure your guitar's neck is properly maintained.

• String 6 (Low E): Tune down 3 semitones to C#3. Caution is advised for this adjustment.
• String 5 (A): Tune down 3 semitones to F#3. Caution is advised for this adjustment.
• String 4 (D): Tune down 3 semitones to B2. Caution is advised for this adjustment.
• String 3 (G): Tune down 1 semitone to F#4.
• String 2 (B): Keep as is; no change (0 semitones) to B3.
• String 1 (High E): Keep as is; no change (0 semitones) to E4.

Note on String Gauges: While adjustments of -3 semitones are often manageable with standard string gauges, always proceed carefully, and be mindful of string tension. For changes exceeding 4 semitones (either up or down), considering a different string gauge (e.g., heavier for lower tunings, lighter for higher tunings) is generally recommended to optimize tone, maintain proper string tension, and prevent potential damage to your instrument.
