This is a highly unconventional and distinct 6-string guitar tuning, described by the user as something they use for their band. It deviates significantly from standard tuning and even common drop tunings, suggesting it's tailored for a very specific sonic palette and playing style.

Verbal Analysis

The most striking feature of this tuning is its extreme range and the reordering of pitches between adjacent strings. The lowest string is a very deep A1, providing a foundation for incredibly heavy and resonant riffs. However, the subsequent strings feature large interval jumps, sometimes even tuning up from a lower-pitched string to a higher one (e.g., 4th string A2 is lower than 5th string E3) and vice-versa (1st string B3 is lower than 2nd string F#4). This "crossed-string" arrangement creates a unique harmonic landscape that will make traditional chord shapes unplayable, demanding a fresh approach to the fretboard. It's likely designed for powerful, non-standard voicings, dissonant textures, or specific melodic runs across non-adjacent strings. The large semitone movements required for tuning also suggest the need for careful string gauge selection.

Technical Analysis

• Overall Range: The tuning spans a vast range from A1 to F#4, covering approximately 2.5 octaves, but with highly irregular steps.
• Lowest String: The 6th string at A1 provides a very low fundamental, typical of heavy genres, much lower than the standard low E2.
• Octave Pairing: The 6th string (A1) and 4th string (A2) form a perfect octave, which is excellent for thick, resonant power chords on the lowest registers.
• Unconventional Intervals:
  • String 6 (A1) to String 5 (E3): A massive jump of +31 semitones.
  • String 5 (E3) to String 4 (A2): A descending interval of -7 semitones, where the fifth string is higher than the fourth.
  • String 4 (A2) to String 3 (D3): A standard perfect fourth (+5 semitones).
  • String 3 (D3) to String 2 (F#4): Another large jump of +14 semitones (an octave and a major third).
  • String 2 (F#4) to String 1 (B3): A descending interval of -7 semitones, where the second string is higher than the first.
• Open String Chords / Voicings:
  • The open strings A1-E3-A2-D3-F#4-B3 do not form a conventional chord across all strings due to the irregular intervals and reordering.
  • However, the lowest two A strings (A1, A2) and the D3 (String 3) can be used to form a powerful A5 chord (A-A-D) by ignoring the 5th string (E3).
  • Strings 4, 3, 2 (A2, D3, F#4) explicitly spell out an A Major triad, offering a bright open major chord in the mid-range. This is a very useful voicing within the tuning.
  • The unique sequence encourages fingerings that span non-adjacent strings or employ open string drones for harmonic effect.

Here are the specific notes for each string of this tuning, from thickest to thinnest:

• String 6 (Low E): A1
• String 5 (A): E3
• String 4 (D): A2
• String 3 (G): D3
• String 2 (B): F#4
• String 1 (High E): B3

How to Tune

To achieve this unique tuning, start from standard EADGBe tuning and adjust each string as follows. Please exercise caution when tuning, especially with large semitone changes, and consider using appropriate string gauges.

• String 6 (Standard E2): Tune down 7 semitones to A1. (Warning: Tuning down 7 semitones is a significant drop; a much heavier gauge string is strongly advised for proper tension and tone.)
• String 5 (Standard A2): Tune up 7 semitones to E3. (Warning: Tuning up 7 semitones is a very large increase in tension; a lighter gauge string may be necessary to prevent breakage and avoid excessive neck tension.)
• String 4 (Standard D3): Tune down 5 semitones to A2. (Warning: Tuning down 5 semitones is a substantial drop; a heavier gauge string is advised.)
• String 3 (Standard G3): Tune down 5 semitones to D3. (Warning: Tuning down 5 semitones is a substantial drop; a heavier gauge string is advised.)
• String 2 (Standard B3): Tune down 5 semitones. (Warning: Tuning down 5 semitones is a substantial drop; a heavier gauge string is advised.)
• String 1 (Standard E4): Tune down 5 semitones to B3. (Warning: Tuning down 5 semitones is a substantial drop; a heavier gauge string is advised.)
