The "D#F#BD#A#C#" tuning, intriguingly described as "What Do You Want- German Error Message," is an experimental and harmonically rich setup for the Guitar. This tuning drops every string significantly from standard EADGBe, creating a deep, resonant, and somewhat melancholic soundscape.

Technical Analysis:

• The open strings sound as D#3, F#3, B2, D#4, A#4, C#5.
• When strummed open, these notes form a complex and lush D# minor 7 (add 6) chord:
  • D# (Root - String 6 & 3)
  • F# (Minor Third - String 5)
  • A# (Perfect Fifth - String 2)
  • C# (Minor Seventh - String 1)
  • B (Major Sixth - String 4)
• The presence of the root D# on both the 6th and 3rd strings provides a strong, resonant foundation and octave separation.
• The intervals between some strings are particularly conducive to specific chord voicings: the 5th and 4th strings (F# to B) form a perfect fourth, while the 4th and 3rd strings (B to D#) form a minor third. The 3rd and 2nd strings (D# to A#) form a perfect fifth, and the 2nd and 1st strings (A# to C#) form a minor third. This allows for interesting intervallic patterns to be easily formed across the neck.
• This tuning naturally lends itself to compositions in the key of D# minor, providing all the essential chord tones and extensions readily available on open strings.

Verbal Analysis & Applications:

The "D#m7(add6) Open Tuning" creates an incredibly atmospheric and evocative sound. The deep pitches and rich harmonic content suggest applications in genres requiring depth and emotional resonance, such as progressive rock, ambient music, metal, or even contemporary jazz. The inherent D# minor 7 (add 6) chord provides an immediate, complex harmony, making it excellent for drone-based music or open-string arpeggios that shimmer with a dark, sophisticated quality. Players will find that simple barres can often yield expansive, full chords due to the carefully chosen open string intervals, opening up new harmonic possibilities and easing fingerings for complex voicings in the D# minor key.

How to Tune to D#m7(add6) Open Tuning:

This tuning requires significant detuning for most strings from standard EADGBe. Please proceed carefully and ensure your guitar's intonation is checked after tuning.

• String 6 (Low E): Tune down from E3 to D#3. Tune down 1 semitones.
• String 5 (A): Tune down from A3 to F#3. Tune down 3 semitones.
• String 4 (D): Tune down from D3 to B2. Tune down 3 semitones.
• String 3 (G): Tune down from G4 to D#4. Tune down 4 semitones. Note: This is a significant drop; consider a heavier gauge string if this tuning is used frequently.
• String 2 (B): Tune down from B4 to A#4. Tune down 1 semitones.
• String 1 (High E): Tune down from E5 to C#5. Tune down 3 semitones.

As several strings are tuned down by 3 or 4 semitones, it's advisable to consider using a slightly heavier gauge string set to maintain proper tension and intonation, especially for the 3rd string which drops 4 semitones.
