This unique guitar tuning, famously used by John Mayer on his song "Neon" from the "Room for Squares" album, is specifically tailored for a Novax Expression Solidbody 6 guitar with fanned frets. Mayer notably employs a distinctive strumming technique for "Neon," utilizing only his thumb and index finger. Live performances of the song often feature an extended introduction, showcasing the versatility of this setup.

Technical Analysis

Technically, this tuning is a variation of standard EADGBe, distinguished by a significant drop of the low E string. The full tuning sequence is C-A-D-G-B-e. The low C (C2) provides a deep, resonant foundation, significantly extending the guitar's bass range and opening up possibilities for heavier, more bass-driven riffs. The open strings themselves (C-A-D-G-B-e) do not form a conventional major or minor chord, but the interval between the 6th string (C) and the 5th string (A) creates a major sixth, implying a C6 tonality or an A minor triad with an added C bass. The top three strings (G-B-e) remain in standard tuning, meaning many familiar chord shapes and melodic lines for the higher register are still readily accessible. This blend allows for the preservation of standard melodic capabilities on the higher strings while benefiting from the deep, extended bass range. Power chords rooted on the low C string will be particularly impactful and full-bodied.

How to Tune

To achieve this "Major Sixth" tuning from standard EADGBe (E2-A2-D3-G3-B3-E4), follow these steps:

• 6th String (Low E): Tune down 4 semitones to C. (Note: Tuning down 4 semitones is a significant change. While possible on standard gauges, for optimal tone, stability, and playability with the lower tension, a heavier gauge string for the low C may be advisable.)
• 5th String (A): Keep as is; no change (0 semitones).
• 4th String (D): Keep as is; no change (0 semitones).
• 3rd String (G): Keep as is; no change (0 semitones).
• 2nd String (B): Keep as is; no change (0 semitones).
• 1st String (High E): Keep as is; no change (0 semitones).
