This is the Charlie Hunter 7 String Up A Step tuning for a 7-String Guitar. As indicated in its description, this tuning is a unique interpretation of the Charlie Hunter 7-string style, specifically featuring a major third interval between the 1st and 2nd strings, conceptually shifted up a whole step from a hypothetical standard. This setup is designed to offer distinct voicings and expanded harmonic possibilities, making it ideal for players who wish to integrate sophisticated chordal work with bass lines.

The open string notes are A1-D2-G2-D3-G3-C4-E4. This arrangement creates a versatile harmonic foundation:

• The lowest three strings (7th, 6th, and 5th) are tuned to A1-D2-G2. Played together, these notes strongly suggest a D suspended 4th chord with an A in the bass, or an A minor suspended 4th, providing a deep, resonant foundation.
• Moving up, the 5th (G2), 4th (D3), and 3rd (G3) strings form an open G major triad or power chord (G-D-G), offering a clear major tonality.
• The highest three strings (3rd, 2nd, and 1st) are tuned to G3-C4-E4. This forms a clear C Major triad in its first inversion (G-C-E), providing bright and readily accessible major voicings in the upper register.

Overall, the tuning facilitates the creation of lush C major and G major voicings, while the lower strings provide a robust, open bass for chord-melody playing, jazz, funk, and solo guitar arrangements, reflecting the signature style of Charlie Hunter.

How to Tune:

To achieve the Charlie Hunter 7 String Up A Step tuning from a standard 7-string guitar setup, follow these precise adjustments for each string, based on the provided string movements:

• 7th String (Lowest): Tune down 2 semitones to A1.
• 6th String: Tune down 2 semitones to D2.
• 5th String: Tune down 2 semitones to G2.
• 4th String: Keep as is; no change (0 semitones) to D3.
• 3rd String: Keep as is; no change (0 semitones) to G3.
• 2nd String: Tune up 1 semitone to C4.
• 1st String (Highest): Keep as is; no change (0 semitones) to E4.

Important Note: All string adjustments in this tuning are relatively minor, with movements not exceeding 2 semitones down or 1 semitone up. Therefore, a change in string gauge is generally not required to comfortably achieve and maintain this tuning.

Here are the specific notes for each string in the Charlie Hunter 7 String Up A Step tuning, from lowest (7th) to highest (1st):

• 7th String: A1
• 6th String: D2
• 5th String: G2
• 4th String: D3
• 3rd String: G3
• 2nd String: C4
• 1st String: E4
