This tuning, famously associated with experimental rock band Sonic Youth, plunges your guitar into a world of resonant drones and stark dissonances. It's not designed for traditional chord progressions but rather for creating rich, sustained textures, open-string reverberations, and clashing harmonies that demand attention. The repeated unisons and close intervals between certain strings create a thick, almost muddy sonic landscape that can be both beautiful and jarring, perfect for noise rock, avant-garde, or atmospheric music. It encourages exploration beyond standard fretboard shapes, inviting you to discover unique voicings and percussive possibilities. As the original description notes, this specific tuning was "found on sonicyouth.com," immediately signaling its experimental and unconventional nature.

Analyzing the open strings, the tuning presents D#3, D#3, C#4, C#4, G#4, G4. From low to high, the intervals are as follows:
The lowest two strings (6 & 5) are a unison D#3, providing a deep, foundational drone.
Strings 4 & 3 are a unison C#4, creating a minor second (semitone) interval with the D# drones below (D# to C#). This fundamental clash is key to the tuning's character.
String 2 is a G#4, forming a perfect fifth with the C# below (C# to G#). This offers a moment of consonant harmony within the otherwise tense structure.
The highest string, G4, introduces the most striking dissonance: a minor second down from the G#4 on string 2 (G# to G). This deliberate semitone clash on the top strings is a hallmark of many experimental tunings, providing a strong, ringing friction.

This tuning does not lend itself to easy formation of common major or minor triads in the open position. Instead, it offers a distinct C#sus2/sus4 type voicing (C#-G#-D#) with a D# drone and a highly dissonant G on top. Players might find interesting open power chords or two-string intervals by barring across the C# and G# strings (4, 3, 2). The close proximity of D# and C# (strings 6, 5, 4, 3) will naturally lead to minor second intervals being prominent. The open tuning itself is a resonant cluster, perfect for strumming as a single, complex chord.

Caution on String Tension: Players should note significant string tension changes for strings 5 and 3. These strings are tuned down by 6 semitones each, exceeding the general recommendation of -4 semitones for standard gauges. For these strings, a lighter gauge string is strongly advised to maintain playability, prevent excessive floppiness, and ensure optimal intonation. Playing with such a drastic drop in tension on a standard gauge string may lead to buzzing and difficulty staying in tune.

• String 6 (Low E): Tuned to D#3.
• String 5 (A): Tuned to D#3.
• String 4 (D): Tuned to C#4.
• String 3 (G): Tuned to C#4.
• String 2 (B): Tuned to G#4.
• String 1 (High E): Tuned to G4.

How to Tune:

To achieve this unique tuning from standard EADGBe, follow these steps:

• String 6 (Low E): Tune down 1 semitone to D#3.
• String 5 (A): Tune down 6 semitones to D#3. (Significant drop; a lighter gauge string is recommended).
• String 4 (D): Tune down 1 semitone to C#4.
• String 3 (G): Tune down 6 semitones to C#4. (Significant drop; a lighter gauge string is recommended).
• String 2 (B): Tune down 3 semitones to G#4.
• String 1 (High E): Tune up 3 semitones to G4.
