Tuning Analysis: Open C#6

This unique tuning, originally conceived for 'experimenting with various tunings for guitar composition', transforms your guitar into a vibrant and full Open C# Major 6 chord. It creates a bright and resonant soundscape, suggesting its suitability for rich strumming, slide guitar, or fingerstyle where a harmonically complete sound is desired with minimal fingering. The arrangement of notes, particularly the higher octaves on the thinner strings, gives it a distinct character.

Technical Breakdown:

The open strings are tuned to C#3, G#3, A#3, F3, G#4, C#5. This configuration outlines a C# Major 6 chord (C# - F - G# - A#) spread across multiple octaves. Specifically:

• 6th String (Lowest): C#3 (Root)
• 5th String: G#3 (Perfect 5th)
• 4th String: A#3 (Major 6th)
• 3rd String: F3 (Major 3rd)
• 2nd String: G#4 (Octave Perfect 5th)
• 1st String (Highest): C#5 (Two Octaves Root)

The presence of the Major 3rd (F) and Major 6th (A#) along with the root and fifth provides a complete major chord sonority right out of the box. The higher octave repetitions of G# and C# on the thinner strings add sparkle and depth, giving the tuning a somewhat 'high-strung' or mandolin-like character in its upper register, while the low C# anchors the sound with a solid bass foundation.

Chordal Possibilities:

• Open C#6: Simply strumming all open strings produces a rich and full C# Major 6 chord, making it ideal for immediate harmonic impact.
• Barred Chords: Due to the open chord structure, barring across any single fret will easily produce other Major 6 chords. For example, barring the 1st fret yields a D Major 6, the 2nd fret a D# Major 6, and so on.
• Root-Fifth Power Chords: The presence of C# and G# on the lower strings (6th and 5th) and G# on the 2nd string facilitates easy formation of power chords by muting other strings.
• Melodic Playing: The open strings provide a strong harmonic foundation, allowing for melodic lines to be played against a sustained C#6 drone or chord. The varied octaves of C# and G# offer interesting melodic voicing options.

Considerations:

This tuning involves significant string tension adjustments, with all strings tuned down from what is typically considered standard. Players should be mindful of string gauge, especially for the 4th string, where a 4-semitone drop might benefit from a different gauge to maintain optimal playability and intonation.

How to Tune:

• String 6 (Lowest E string): Tune down 3 semitones to C#3.
• String 5 (A string): Tune down 1 semitone to G#3.
• String 4 (D string): Tune down 4 semitones to A#3. (Note: Tuning down 4 semitones on this string may cause it to feel loose or require a heavier gauge string for optimal performance.)
• String 3 (G string): Tune down 2 semitones to F3.
• String 2 (B string): Tune down 3 semitones to G#4.
• String 1 (Highest E string): Tune down 3 semitones to C#5.
