The "Viola da Gamba Tuning" (D-G-C-E-A-D) is a unique and resonant alternative to standard guitar tuning, borrowed directly from the historical Lute and Viola da Gamba family of instruments. It positions the open strings to create a rich, open Dsus4add9 chord, featuring the notes D, G, C, E, A, D from low to high. This tuning offers a distinct sonic palette, characterized by its deep, mellow qualities and inherent polyphony.

Technically, the interval structure of this tuning is a series of perfect fourths (P4) with one major third (M3): P4 (D-G), P4 (G-C), M3 (C-E), P4 (E-A), P4 (A-D). This configuration closely mimics that of a standard Viola da Gamba and provides a different approach to chord voicings compared to a standard guitar. The strategic placement of the Major 3rd between the 4th (C) and 3rd (E) strings is a key differentiator from the standard guitar tuning's M3 between the G and B strings.

As the original description highlights, this tuning is exceptionally useful for its more moveable chord shapes. The predominantly perfect fourth intervals make it easier to transpose chord forms across the fretboard. A significant advantage is the natural resonance of open suspension chords; the open strings D-G-C-E-A-D already contain the notes for Dsus2 (D-E-A) and Dsus4 (D-G-A), and even a full C Major triad (C-E-G) is found on the 4th, 3rd, and 5th strings respectively. This means that C major can be played with remarkable fullness by simply playing the open 4th, 3rd, and 5th strings, possibly augmented with the 6th string at the 8th fret (C) and 2nd string at the 3rd fret (C) for a C-G-C-E-C-C voicing. Similarly, a rich G Major chord (G-G-D-G-B-G) can be formed by using the 5th string open (G) and fretting other strings accordingly. This tuning lends itself beautifully to fingerstyle playing and allows for lush, complex harmonies with relatively simple fingerings, making it a compelling choice for exploring early music, folk, and contemporary compositions alike.

Open String Notes:

• 6th String (Low E): D2
• 5th String (A): G2
• 4th String (D): C3
• 3rd String (G): E3
• 2nd String (B): A3
• 1st String (High E): D4

How to Tune:

To achieve the Viola da Gamba Tuning (D-G-C-E-A-D) from standard EADGBe, follow these steps. Please tune carefully and gradually. All strings will be tuned down.

• 6th String (Low E): Tune down 2 semitones to D2.
• 5th String (A): Tune down 2 semitones to G2.
• 4th String (D): Tune down 2 semitones to C3.
• 3rd String (G): Tune down 3 semitones to E3.
• 2nd String (B): Tune down 2 semitones to A3.
• 1st String (High E): Tune down 2 semitones to D4.

Important Note on String Gauge: All tuning adjustments for this specific tuning involve tuning down. The largest drop is 3 semitones on the 3rd string (G to E), which is generally safe for standard gauge strings. However, if you plan to use this tuning extensively, or combine it with other tunings involving significant upward tension, consider string gauges optimized for lower tunings to maintain optimal tension and tone. Extreme tuning changes (exceeding 4 semitones up or down) typically require a different string gauge to prevent breakage or excessive looseness.
