D#D#GA#DG | E♭E♭GB♭DG Bug Collector Capo 6 - Guitar tuning, chords & scales
The "Open Eb7" tuning, also known by its application name "Bug Collector Capo 6", transforms your guitar into a vibrant and soulful instrument. This tuning is particularly notable for its rich harmonic foundation, making it an excellent choice for blues, R&B, jazz, and rock genres that benefit from a strong dominant seventh feel.
Technical Analysis:
- The open strings are tuned to D#2 (Eb2), D#3 (Eb3), G2, A#3 (Bb3), D3, G3 (from low E to high E).
- These notes collectively form an Eb Dominant 7th chord (Eb7). The intervals relative to the root Eb are: Root (Eb), Octave (Eb), Major Third (G), Perfect Fifth (Bb), Minor Seventh (Db), and an octave of the Major Third (G).
- The doubling of the root (Eb) and the major third (G) provides a full and resonant sound, emphasizing the dominant quality.
- This tuning is inherently designed for "open" chord voicings, where strumming all open strings yields a powerful Eb7 chord. It offers a bluesy or gospel-like resonance naturally.
- Chords within Reach: Barring any fret across all six strings will immediately produce another dominant 7th chord. For example, barring the 1st fret yields an F7, the 3rd fret an Ab7, and so on. This makes transposing dominant 7th chords incredibly intuitive and ideal for slide guitar. While standard major and minor chord shapes will be significantly altered, the open nature encourages creative single-finger barre shapes to achieve different chord qualities or slide playing for melodic lines over the dominant harmony.
- Capo Context: The original context mentions this as the "Tuning for the song “Bug Collector”, with capo on fret 6." This means that while the physical open strings are tuned to Eb7, the song is played with a capo on the 6th fret. This effectively raises the tuning by six semitones, resulting in an A dominant 7th tuning (A2 A3 C#3 D#4 F#3 C#4) *at the capo*. This allows for playing in the key of A with the same chordal benefits but at a higher effective pitch.
How to Tune to Open Eb7 (D#2 D#3 G2 A#3 D3 G3):
Achieving this tuning from a standard EADGBe setup involves significant downward adjustments for all strings. Due to the extreme semitone changes specified, it is highly recommended to use a much heavier gauge string set to maintain proper tension, intonation, and prevent potential string damage or issues with your guitar's neck.
- String 6 (Low E): Tune down 13 semitones to D#2 (Eb2). This is a very substantial drop, far exceeding an octave. A heavier gauge string is essential for playability and guitar health.
- String 5 (A): Tune down 6 semitones to D#3 (Eb3). This is a significant drop; a heavier gauge string is advised for optimal performance.
- String 4 (D): Tune down 7 semitones to G2. This is a substantial drop. Consider a heavier gauge string to maintain tension.
- String 3 (G): Tune down 9 semitones to A#3 (Bb3). This is an extremely large downward adjustment for this string. A much heavier gauge string is strongly advised.
- String 2 (B): Tune down 9 semitones to D3. Another very significant drop, requiring a heavier gauge string for stability.
- String 1 (High E): Tune down 9 semitones to G3. This is a very large downward adjustment. A heavier gauge string is strongly recommended.
Caution: All strings in this tuning are specified to be tuned down by more than 4 semitones from standard EADGBe. Attempting this with a standard light or medium gauge string set can lead to excessively loose strings, poor intonation, fret buzz, and potentially put undue stress on your guitar's neck and bridge. Professional setup and a suitable string gauge (e.g., a "baritone" set or custom gauges) are highly recommended to prevent damage and ensure playability.
