Tuning Overview: Bmadd9

This unique tuning, aptly named Bmadd9, is a compelling variation of the open B tuning, giving it a distinct minor character. As described by its creator, it is perfectly suited for genres like Post Metal, Sludge, Hardcore, and Black Metal, emanating a truly dark and heavy sonic palette. The open strings resonate with a profound, ominous quality, ideal for crafting dense riffs and atmospheric soundscapes.

Technical Analysis: Open Strings & Chords

The open string notes are structured as B1-F#3-B2-D3-F#4-C#5 (from low to high). Analyzing these notes reveals a clear B minor chord (B-D-F#) with an added C#, which is the major ninth. This means that simply strumming the open strings produces a rich and resonant Bm(add9) chord. The repetition of B and F# across different octaves creates a powerful, full sound, while the C# on the high string introduces an intriguing harmonic tension and brightness, preventing the minor chord from feeling overly static. This tuning naturally facilitates the creation of complex minor voicings and allows for easy exploration of dissonant or melodic intervals by barring across the fretboard, yielding parallel Bm(add9) chord shapes.

How to Tune (from Standard E)

To achieve the Bmadd9 tuning from standard E, you will need to adjust each string as follows:

• 6th String (Low E): Tune down 5 semitones to B1.
• 5th String (A): Tune down 3 semitones to F#3.
• 4th String (D): Tune down 3 semitones to B2.
• 3rd String (G): Tune down 5 semitones to D3.
• 2nd String (B): Tune down 5 semitones to F#4.
• 1st String (High E): Tune down 3 semitones to C#5.

Important Note: Several strings require a significant drop in pitch (5 semitones down). While generally safe for the guitar when tuning down, consistent use of such a low tuning may benefit from a heavier string gauge to maintain optimal tension and intonation, especially if your guitar currently uses lighter strings. Extreme changes in pitch (more than 4 semitones up or down) can affect string tension and intonation, and in some cases, might warrant a professional setup.
