The 'Mk' tuning for Guitar is a truly unique and highly customized setup that redefines traditional string pitch relationships. Far from standard, this tuning creates a deep, resonant soundscape centered around the B minor chord when all strings are played open. Its non-sequential pitch order across the strings demands a fresh approach to playing, encouraging exploration of arpeggios, melodic lines, and unconventional chord voicings rather than relying on standard shapes.

Technical Analysis:

Technically, the open string notes are configured as B1-F#3-B2-D3-F#4-D4, moving from the lowest (6th) to the highest (1st) string. This arrangement strategically places multiple octaves of B (B1, B2) and F# (F#3, F#4), alongside D (D3, D4), thereby constructing a comprehensive B minor chord across the instrument's entire open range. Notable intervals between adjacent strings include a substantial ascending Major 10th (19 semitones) from String 6 (B1) to String 5 (F#3), followed by a descending Perfect 4th (7 semitones) from String 5 (F#3) to String 4 (B2). Another significant ascending Major 10th (16 semitones) occurs between String 3 (D3) and String 2 (F#4). These wide and sometimes descending intervals between adjacent strings make traditional chord shapes largely impractical, opening the door for innovative two-note voicings, intricate fingerstyle patterns, and drone-based compositions. The open tuning itself forms a robust B minor chord, making it an excellent foundation for pieces in the key of B minor or for experimenting with its unique harmonic qualities.

Open String Notes:

• String 6 (Low E string position): B1
• String 5 (A string position): F#3
• String 4 (D string position): B2
• String 3 (G string position): D3
• String 2 (B string position): F#4
• String 1 (High E string position): D4

How to Tune:

To achieve the 'Mk' tuning, start from standard tuning and adjust each string as follows. Please exercise caution when tuning, especially with significant changes:

• String 6: Tune down 5 semitones to reach B1. (Note: Tuning down 5 semitones is a substantial change; consider using a heavier gauge string for optimal tension and tone.)
• String 5: Tune down 3 semitones to reach F#3.
• String 4: Tune down 3 semitones to reach B2.
• String 3: Tune down 5 semitones to reach D3. (Note: Tuning down 5 semitones is a substantial change; consider using a heavier gauge string for optimal tension and tone.)
• String 2: Tune down 5 semitones to reach F#4. (Note: Tuning down 5 semitones is a substantial change; consider using a heavier gauge string for optimal tension and tone.)
• String 1: Tune down 2 semitones to reach D4.
