Verbal Analysis:
This unique tuning is often referred to as "Capo 5 (High E Open)" because it effectively emulates the sound of a standard EADGBe guitar with a capo on the 5th fret, with the significant exception of the highest E string (string 1) remaining at its standard open E pitch. This creates a bright, shimmering, and somewhat ambiguous open sound. It's particularly well-suited for styles requiring rich, sustained open string drones, atmospheric textures, and fingerstyle playing where the open strings can resonate together. The bright, high-pitched open strings lend themselves to a bell-like quality, while the lower strings provide a solid, transposed foundation, making it ideal for creating lush, harmonically rich soundscapes.

Technical Analysis:
The open notes for this tuning, from low to high, are A2 - D3 - G3 - C4 - E4 - E4. This tuning is a modified A Standard (ADGCEA) where the B string is tuned up to E and the high E string remains at standard pitch, resulting in a doubled E on the top two strings. The first five strings are uniformly tuned up by a perfect fourth (5 semitones) relative to standard EADGBe, creating a consistent shift in pitch across most of the instrument.

Open Chords and Voicings:

• Strumming all open strings (A-D-G-C-E-E) yields a rich, extended chord. This voicing can be perceived as a C Major 9 with an A in the bass (Cmaj9/A) or an A minor 11. It's a complex, resonant chord that provides a lush and ambient foundation.
• A standard open E Major chord shape (022100) (played on a standard guitar) when applied to this tuning, surprisingly transforms into a full and vibrant A Major chord (A-E-A-C#-E-E). This makes playing in the key of A very accessible and resonant.
• Similarly, a standard open A minor chord shape (x02210) (on a standard guitar) played in this tuning becomes a beautiful D minor suspended 4 (D-A-D-F-E), offering a unique, open-ended sound ideal for melodic exploration and folk-inspired harmonies.
• The duplicated high E strings (string 2 and string 1) at E4 create a natural chorus effect, adding fullness, sustain, and shimmer to melodies and chords played on the higher register.
• This tuning is excellent for creating drone notes and open string arpeggios, particularly around the keys of A and D, allowing for rich, sustained textures and a bright, ethereal sound.

How to Tune (from Standard EADGBe)

To achieve the "Capo 5 (High E Open)" tuning, you will need to adjust your strings from standard EADGBe as follows. Please note that tuning up 5 semitones for most strings is a significant change, and using a lighter gauge string set might be advisable to prevent excessive string tension or breakage. Always tune carefully and check string tension regularly.

• String 6 (Low E): Tune up 5 semitones to A2. (Original E2)
  Recommendation: Tuning up 5 semitones exceeds the general recommendation of +/- 4 semitones for string gauge adjustments. Consider a lighter gauge string for this string or proceed with caution.
• String 5 (A): Tune up 5 semitones to D3. (Original A2)
  Recommendation: Tuning up 5 semitones exceeds the general recommendation of +/- 4 semitones for string gauge adjustments. Consider a lighter gauge string for this string or proceed with caution.
• String 4 (D): Tune up 5 semitones to G3. (Original D3)
  Recommendation: Tuning up 5 semitones exceeds the general recommendation of +/- 4 semitones for string gauge adjustments. Consider a lighter gauge string for this string or proceed with caution.
• String 3 (G): Tune up 5 semitones to C4. (Original G3)
  Recommendation: Tuning up 5 semitones exceeds the general recommendation of +/- 4 semitones for string gauge adjustments. Consider a lighter gauge string for this string or proceed with caution.
• String 2 (B): Tune up 5 semitones to E4. (Original B3)
  Recommendation: Tuning up 5 semitones exceeds the general recommendation of +/- 4 semitones for string gauge adjustments. Consider a lighter gauge string for this string or proceed with caution.
• String 1 (High E): Keep as is; no change (0 semitones) at E4. (Original E4)
