"Open B Rasised E/A" is a unique and atmospheric guitar tuning, specifically designed by its creator for crafting "relaxing indie songs." This tuning deviates from standard, creating a rich harmonic landscape that is both expansive and introspective.

Technical Analysis:

The open strings are tuned to E2 B2 D4# A4# B3 D5#. When strummed open, these notes form a complex yet beautiful harmony. While the name suggests an "Open B" tuning, the notes do not align with a traditional Open B (B F# B E G# B). Instead, the open chord produced contains the notes B (root), D# (major 3rd), A# (major 7th), and E (perfect 4th). This creates a B Major 7th chord with an added 4th (E). The presence of two B notes (B2, B3) and two D# notes (D4#, D5#) across different octaves provides a full, harmonically rich sound. The lowest E2 acts as a stable base or a suspension, adding depth and a slightly melancholic yet resolving quality to the overall B Major 7th character.

This configuration avoids a simple major or minor triad, offering a sophisticated palette of sounds that encourages open, ringing voicings and melodic exploration rather than traditional chord shapes. The wide intervals between some strings, such as the leap from B2 on the 5th string to D4# on the 4th string, contribute to an open, spacious sound, allowing notes to breathe and resonate.

Verbal Analysis & Playability:

As intended by its creator, this tuning is perfectly suited for indie, ambient, or folk styles where rich, sustained harmonies and an unhurried, reflective feel are desired. The open E and B strings can serve as excellent drones, providing a stable foundation for melodic lines or gentle arpeggios on the higher strings. While traditional chord shapes will need to be re-learned, the true beauty lies in exploring the new harmonic possibilities this tuning presents. Simple one-finger barres across certain frets can yield unexpected and beautiful extended chords or inversions. For instance, barring all strings at the 2nd fret would transform the open Bmaj7(add4) into a C#m-like or similar evocative chord, given the existing intervals. The inherent resonance of the open strings makes it easy to create lush soundscapes with minimal effort, perfectly embodying the spirit of 'relaxing indie songs' where mood and texture are paramount.

Open String Notes:

How to Tune:

When tuning your guitar to "Open B Rasised E/A" from standard EADGBe tuning, please follow these specific instructions for each string:

• String 6 (Low E): Keep as is; no change (0 semitones). Target Note: E2
• String 5 (A): Tune up 2 semitones. Target Note: B2
• String 4 (D): Tune up 1 semitones. Target Note: D4#
• String 3 (G): Tune up 3 semitones. Target Note: A4#
• String 2 (B): Keep as is; no change (0 semitones). Target Note: B3
• String 1 (High E): Tune down 1 semitones. Target Note: D5#

Important Note: All string adjustments in this tuning are within a relatively small range (less than 4 semitones up or down). Therefore, a change in string gauge is generally not required, but always exercise caution when tuning strings up, especially if your guitar's neck relief is not regularly checked. If you notice any buzzing or intonation issues, a professional setup may be beneficial.
