The tuning aptly named 'Bmadd9' is, as its creator describes, a result of an "unusual" exploration, perhaps capturing a mood of introspection. This deep and resonant tuning opens up a rich, melancholic soundscape, perfect for atmospheric pieces or somber reflections.

Technical Analysis:

This tuning transforms your guitar into an open Bm(add9) chord. The open string notes are B1, F#3, C#4, D3, F#4, B3. Broken down, this gives you:

• B (Root): Provided by the 6th string (B1) and 1st string (B3), giving a strong, full fundamental.
• D (Minor Third): On the 3rd string (D3), establishing the minor tonality.
• F# (Perfect Fifth): Found on the 5th string (F#3) and 2nd string (F#4), providing harmonic stability and resonance.
• C# (Major Ninth/Major Second): On the 4th string (C#4), adding a rich, open, and slightly suspended quality to the minor chord.

The repetition of B and F# across different octaves creates a lush, layered texture, making this an incredibly resonant tuning. Strumming all open strings yields a beautiful B minor nine chord, ready for immediate musical expression. Its wide range, from the deep B1 to the bright B3, offers a broad sonic palette. Chords that naturally emerge from this tuning will often revolve around B minor, B minor 7th, or B minor 9th voicings, with easy access to drone strings. Experimenting with a capo can shift this rich harmonic structure into other minor keys while maintaining the same intervallic relationships.

How to Tune:

This tuning involves significant detuning for most strings. Standard guitar tuning is E-A-D-G-B-e (from thickest to thinnest string).

• 6th String (Low E): Tune down 5 semitones from E to B1.

  *Caution: Tuning down 5 semitones is a significant drop; consider a heavier gauge string for optimal tension.*

• 5th String (A): Tune down 3 semitones from A to F#3.
• 4th String (D): Tune down 1 semitone from D to C#4.
• 3rd String (G): Tune down 5 semitones from G to D3.

  *Caution: Tuning down 5 semitones is a significant drop; consider a heavier gauge string for optimal tension.*

• 2nd String (B): Tune down 5 semitones from B to F#4.

  *Caution: Tuning down 5 semitones is a significant drop; consider a heavier gauge string for optimal tension.*

• 1st String (High E): Tune down 5 semitones from E to B3.

  *Caution: Tuning down 5 semitones is a significant drop; consider a heavier gauge string for optimal tension.*

Always tune carefully and check string intonation after making large tuning adjustments.
