Verbal Analysis: This is a remarkably unconventional and intricate guitar tuning, far removed from standard configurations. It presents a rich tapestry of sounds, often leaning towards the atmospheric and experimental. The presence of both G# and G natural notes creates a distinct, often haunting dissonance that can be employed for dramatic effect, or as a foundation for complex harmonic structures. A prominent feature is its strongly re-entrant nature, where multiple strings are tuned to pitches lower than their higher-numbered counterparts (e.g., the 3rd string is lower than the 4th, and the 1st string is lower than the 2nd). This design encourages a departure from traditional chord voicings and opens up a realm of unique fingerpicking patterns, drones, and arpeggios that utilize the wide, sometimes unexpected, intervallic jumps. It's a tuning that rewards exploration and can inspire truly original compositions, particularly suited for ambient, folk, or avant-garde styles.

Technical Analysis: The absolute tuning from low to high is G#3 C#4 D#4 G3 D#5 F4.

• Re-entrant Structure: This tuning exhibits two significant re-entrant pairs:
  • The 3rd string (G3) is tuned lower than the 4th string (D#4).
  • The 1st string (F4) is tuned lower than the 2nd string (D#5).
  This creates a non-linear pitch progression across the fretboard, requiring players to rethink their approach to scale and chord construction.
• Open String Chords & Voicings:
  • The lowest three strings (G#3 C#4 D#4) naturally form an open G#sus4 chord, providing a strong tonal center.
  • The full open tuning (G#3 C#4 D#4 G3 D#5 F4) creates a complex voicing. The presence of G# and G natural can be used to generate tension or a bluesy inflection.
  • While traditional major/minor open chords are not immediately available, the tuning is ripe for drone effects, percussive muted strums, and specific interval-based melodic lines.
  • Unique chord shapes can be discovered by fretting across adjacent re-entrant strings, offering fresh harmonic possibilities that are challenging to achieve in standard tuning. For instance, fretting the 6th, 5th, and 4th strings at the first fret would yield A, D, E, retaining the suspended quality but in a new key.
• Dynamics & Playability: The significant upward tuning required for several strings (up to 4 semitones) means that players should monitor string tension. For sustained use, considering a slightly lighter string gauge might be beneficial for strings tuned up by 4 semitones to ensure optimal playability and prevent excessive stress on the instrument.

How to Tune

To achieve the G# Split Octave Re-entrant tuning, follow these string adjustments. Note that movements of 4 semitones or more (up or down) might warrant considering a different string gauge for optimal tension and guitar health.

• String 6: Tune up 4 semitones to G#3.
• String 5: Tune up 4 semitones to C#4.
• String 4: Tune up 1 semitones to D#4.
• String 3: Keep as is; no change (0 semitones) to G3.
• String 2: Tune up 4 semitones to D#5.
• String 1: Tune up 1 semitones to F4.

String 6 (Low E): Tuned up to G#3 (G sharp three)
String 5 (A): Tuned up to C#4 (C sharp four)
String 4 (D): Tuned up to D#4 (D sharp four)
String 3 (G): Tuned to G3 (G three)
String 2 (B): Tuned up to D#5 (D sharp five)
String 1 (High E): Tuned up to F4 (F four)
