This unique 7-string tuning, which we’ve named E G# Minor Charango, offers an intriguing sonic landscape. Drawing inspiration from the vibrant sounds of Charango tunings, it aims to provide a familiar yet expanded sonic palette for players, especially those accustomed to ukulele tunings, by extending these concepts onto a guitar. The presence of two identical low E strings (E2) creates a distinct and resonant bass foundation, offering a thicker, more sustained low end that is highly unusual and adds significant depth.

While the original description hints at a "GCEA" middle, the actual notes (G3#, C3, E3, A3 for strings 5-2) introduce a more complex, somewhat darker harmonic texture. This combination leans towards an augmented or minor-infused sound rather than a straightforward major ukulele chord. This makes it an excellent choice for players looking to explore unconventional harmonies, ambient textures, or emulate the rich, percussive qualities of a Charango with added, deep resonance. It is particularly well-suited for fingerstyle playing where individual string qualities can shine, or for experimental compositions where standard major/minor voicings are less desired.

Technical Analysis

The open string notes for this tuning are: E2, E2, G3#, C3, E3, A3, E4.

Harmonically, if strummed openly, the notes present are E, G#, C, A (ignoring the doubled E). This unique combination forms an A minor-major 7 chord (A-C-E-G#) with a low E drone, or an E Augmented chord (E-G#-C) with an added A. This provides a rich, somewhat dissonant yet highly evocative open voicing that can be both surprising and inspiring. The wide intervallic spread and the presence of the G# and C create a distinctive texture that departs significantly from standard guitar tunings.

Chordal Possibilities: While not immediately conducive to standard open major/minor chords, this tuning's unique structure strongly encourages open voicings and drone-like qualities. The G3#, C3, E3, A3 sequence in the middle strings (5-2) can naturally create suspended or jazz-inflected voicings with minimal effort. Exploring these strings with simple one-finger barres or partial chords can yield sophisticated, atmospheric results. This tuning thrives on experimentation and finding new chord shapes that leverage its inherent harmonic tensions and resolutions.

String Gauge Considerations: Given the significant upward adjustment of String 7 by +5 semitones, we strongly advise considering a lighter gauge string for this particular string. This will help prevent excessive tension, reduce the risk of string breakage, and ensure more stable intonation, allowing you to fully explore the tuning's unique potential without compromise.

How to Tune

To achieve the E G# Minor Charango tuning, follow these precise adjustments for each string from lowest (String 7) to highest (String 1):

• String 7 (E2): Tune up 5 semitones. (Note: A substantial upward tuning. A lighter gauge string is advised.)
• String 6 (E2): Keep as is; no change (0 semitones).
• String 5 (G3#): Tune down 1 semitone.
• String 4 (C3): Tune down 2 semitones.
• String 3 (E3): Tune down 3 semitones.
• String 2 (A3): Tune down 2 semitones.
• String 1 (E4): Keep as is; no change (0 semitones).
