Understanding Alternate Tunings
What Are Alternate Tunings?
Alternate tunings redefine the relationship between a guitar’s strings by adjusting intervals or absolute pitch, diverging from the standard EADGBE tuning. Unlike standard tuning’s systematic fifths (E→A, A→D, etc.), alternate tunings modify these intervals—either raising, lowering, or reconfiguring string notes—to create distinct sonic character, playing ease, or harmonic possibilities. For instance, dropping the 6th string from E to D (forming Drop D) is a simple variation, while more complex tunings (like DADGAD) rearrange multiple strings to evoke folk or Celtic tones. Essentially, alternate tunings let guitarists "rewrite" the instrument’s harmonic language, turning familiar chords into fresh sounds.
Why Use Alternate Tunings?
The benefits of alternate tunings extend beyond aesthetics:
- Tonal Versatility: Lower tunings (e.g., Drop C, Dropped D) compress tonal ranges, emphasizing gutural basslines in metal. Open tunings (Open G, Open D) brighten midranges, ideal for bluesy slide work.
- Physical Efficiency: Reducing string tension (e.g., tuning to a diatonic scale like DADGAD) eases finger movement, enabling faster sweep picking or barres in complex passages.
- Creative Freedom: For songwriters, alternate tunings unlock unexpected chord voicings. DADGAD, for example, naturally forms 7th chords with fewer frets, sparking melodic ideas.
- Genre Adaptation: Rockers lean on Drop D for breakdowns; alternative musicians use Standard Half-Step Down to darken vocal harmonies; classical crossover players adopt tunings like ADADG to mimic lute-like resonance.
- Minimal Effort, Maximum Impact: Open tunings let guitarists play "open" chords (no fretting) instantly, turning a 5-second chord transition into a seamless melody.
Common Alternate Tunings for Electric Guitars
Certain alternate tunings have become staples for electric guitarists:
- Drop D (DADGBE): 6th string (E→D), others standard (A-D-G-B-E). A metal/rock favorite, it emphasizes heavy root notes and simplifies power chords (e.g., D5 on 6/5/4 strings).
- DADGAD: 6→D, 5→A, 4→D, 3→G, 2→A, 1→D. An open-tuned Celtic classic, it pairs with harmonics to create haunting, resonant arpeggios (Simon & Garfunkel’s "Scarborough Fair" uses this).
- Dropped C (C-A-D-G-B-E): 6th string (E→C), ideal for low-end-driven genres (post-rock, doom metal). Its scale fits basslines spanning three octaves.
- Standard Half-Step Down (EbADGBE): All strings lowered by a half-step. This darkens standard chords, making them feel heavier and more melodically versatile for vocal pairing.
- Open G (6→G, 5→D, 4→G, 3→G, 2→D, 1→G): The "bluesman’s tool," allowing instant G, D, and C chords with minimal fretting. Slide guitarists use it for open-string bends without muting.
Essential Tools for Alternate Tunings
Tuning Hardware & Software
To master alternate tuning, the right gear streamlines precision:
Hardware:- Clip-On Tuners: Portable, clamp-to-headstock models (e.g., Snark ST-2, Korg TU-10) detect vibrations via sensors or microphones, offering live accuracy for on-the-fly adjustments.
- Locking Tuners: Systems like Floyd Rose or Gotoh’s Locking Nut prevent string slippage, critical for rapid tuning changes or whammy-bar use.
- Precision Wrenches: 1.27mm hex keys ensure smooth adjustment of locking tuners without stripping gears.
- Resonant Meters: Digital tools (Korg PA-1000) display frequency vs. interval ratios, ensuring perfect fifths/disjunctions in complex tunings.
- Mobile Apps: GuitarTuna and Fender Tune offer real-time frequency graphs and preset tuning libraries, ideal for learning DADGAD or Dropped C.
- DAW Integration: VST plugins like "GuitarTune" or Ableton’s Tuner effect sync with Pro Tools, enabling studio-grade tuning during laydowns.
Pre-Tuning Checks & Testing
Before altering strings:
- Neck Relief: Verify the truss rod to fix buzz or string height issues. A slight convex bow (1.5–2mm at the 12th fret) prevents muting in alternate tunings.
- String Stability: Lubricate tuning keys with graphite spray to reduce tension loss. New strings need 24 hours to "settle" before accurate tuning.
- Resonance Testing: After tuning, strum open chords and listen for overtones. Uneven resonance signals loose bridge saddles or dead strings—tighten bridge screws or replace strings.
- Playability Check: Test barres in low tunings (e.g., Drop C) to ensure 6th through 1st strings maintain even tension across the fretboard.
By combining these tools and techniques, electric guitarists can unlock alternate tunings’ full potential—transforming chord progressions, guitar tone, and creative expression.
Step-by-Step Tuning Guides
Drop D Tuning Tutorial
Starting from Standard Tuning (EADGBE: 6th=E, 5th=A, 4th=D, 3rd=G, 2nd=B, 1st=E), Drop D requires only adjusting the 6th string to transform the instrument’s tonal identity.
Step 1: Target Tuning ConfirmationDrop D (DADGBE) sets the 6th string to D, while all others remain standard. This reduces string tension by 12%, creating a lower, more guttural fundamental tone—ideal for palm-muting, breakdowns, and power-chord-driven aggression.
Step 2: String-by-String Adjustment- 6th String: Resonates at D (146.83Hz). Loosen the tuning peg until slack, then slowly tighten while monitoring a clip-on tuner clipped to the 6th string’s headstock. A clear "D" with minimal overtones indicates proper tension.
- Verify Stability: Strum the 1st–5th strings (E,A,D,G,B) to confirm they retain Standard tuning. Test a 6th string open chord (D) against a reference note (e.g., a D note from a keyboard) to ensure octave consistency.
- Gauge Selection: Use heavier strings (0.13–0.56 gauge) to retain sustain; lighter strings (0.11–0.54) may sacrifice timbre in low tunings.
- Chord Workflow: Power chords become second nature: D5 (6-5-4 open), A5 (5-4-3 open), and G5 (4-3-2 open). Lower tunings compress chord voicings, so chord transitions like D5→A5 in "Smells Like Teen Spirit" gain weight.
Open E Tuning Tutorial
Open E (E-B-E-G♯-B-E) brightens midrange tones while retaining open-string resonance, making it a staple for slide work, blues, and southern rock ballads.
Step 1: Standard vs. Open EStandard: E-A-D-G-B-E → Open E: E-B-E-G♯-B-E. Key shifts: 5th string (A→B, half-step), 4th string (D→E, whole-step), 3rd string (G→G♯, half-step).
Step 2: Precision Tuning- 5th String: Tune from A to B using a chromatic tuner (e.g., Snark ST-2).
- 4th String: Lower D to E by aligning with a tuning fork’s E (329.63Hz).
- 3rd String: Raise G to G♯ by fretting the 1st fret on the 6th string (E→F♯, but no—just ensure the string reads G♯, not G or A).
If the G♯ string buzzes at the 12th fret, check for nut alignment or excess fret wear. A well-adjusted truss rod ensures the 3rd string doesn’t clash with adjacent strings.
Master Techniques- Delta Blues Slides: Slide a bottleneck slide on the 2nd–4th frets of the 6th string and 1st string to evoke Robert Johnson’s "Cross Road Blues."
- Vibraphone-Like Chords: Strum 1st (E), 4th (E), and 6th (E) strings while fretting 2nd string at 2nd fret (B→D) for a suspended E major (E-G♯-D) voicing.
DADGAD Tuning Tutorial
DADGAD (D-A-D-G-A-D) is a "living chord factory," where 1st, 4th, and 6th strings all ring D, creating drone-like overtones. Once mastered, it’ll turn folk songs into cinematic soundscapes.
Step 1: Target String ConversionStandard: E-A-D-G-B-E → DADGAD: D-A-D-G-A-D. Three adjustments: 1st (E→D), 2nd (B→A), 6th (E→D).
Step 2: Step-by-Step Tuning- 6th String: Tune from E to D (half-step down). Use a tuner to hit 146.83Hz.
- 2nd String: Tune from B to A (half-step down). Use the 5th string’s A as a reference (tune 5th string first to A).
- 1st String: Tune from E to D (half-step down). Match the 6th string’s D (146.83Hz) for octave unison (293.66Hz).
Pluck all open strings: D (6), A (5), D (4), G (3), A (2), D (1). The 1st and 4th strings should resonate in perfect octaves; misalignment causes "flutter" in complex chord progressions.
Celtic Voice LeadingStrum the 1st (D), 2nd (A), 3rd (G), 4th (D) strings for a Dm7 arpeggio—no frets needed. Add movement with hammer-ons from open 2nd string (A) to fretted 2nd chord (A→D), crafting melodic runs like "Scarborough Fair."
Creative Applications
Alternate tunings let artists transcend traditional scales, turning technical limitations into stylistic signatures. Here’s how genres harness these tonal tools:
Metal/Hard Rock with Alternate Tunings
Metal demands low-end aggression and breakdown-driven energy, which alternate tunings amplify:
- Drop C#/C: Slipknot (Vol. 3, "People = Shit") and Meshuggah (Chaosphere) use Drop C (6th=C) to collapse harmonics, creating 100% distortion-optimized power chords.
- Standard Half-Step Down (EbADGBE): Metallica’s 1990s albums used this to deepen vocal harmonies while maintaining mid-range clarity.
- Tuning Exoticism: Gojira’s Joe Duplantier uses a "DADGAD + 1/4 Step Down" hybrid, adding Drop D’s bass and DADGAD’s Celtic drones to "The Cell" (L’Enfant Sauvage).
Indie/Alternative with Alternate Tunings
Indie and alt-rock prioritize texture and emotional resonance, leveraging tunings like:
- Open G Half-Step Down (G-C#-G-C#-D-G): Bon Iver’s "Holocene" uses this to darken vocal harmonies with a muted, cathedral-like timbre.
- DADGAD in Ambient Passages: Arcade Fire’s "My Body Is a Cage" incorporates DADGAD’s D-A-D triads for orchestral folk bridges, mimicking string section drones.
- Low E Half-Step (C#ADGBE): Phoebe Bridgers’ "Kyoto" uses a 5th string drop to C# for ghostly arpeggios, highlighting lyricism over distortion.
Jazz/Fusion with Alternate Tunings
Jazz/Fusion thrives on unexpected tonal curves, achieved via:
- Open G (G-D-G-B-D-G): Jaco Pastorius’ upright bass influence seeps into guitar play as Herbie Hancock’s "Chameleon Theme" uses this tuning’s G-B-G triads for percussive lead lines.
- Tuning to 7th Chord Intervals: Pat Metheny’s "Phase Dance" employs DADGAD-derived tunings to "map" harmonic spaces, letting him jump between Dmaj7 and Gm7 without retuning.
- Standard Half-Step Down (EbADGBE): Wynton Marsalis’ crossover jazz album "Jazz Chamber Music" uses this to darken "Take the A Train" with 9ths and 11ths voicings.
By redefining harmonic "home base," alternate tunings aren’t just stylistic choices—they’re keys to unlocking new emotional and technical frontiers in guitar work, whether shredding in Drop D or evoking Appalachian roots in DADGAD. For artists, these tunings are less about "fixing" the instrument and more about rewriting its songbook.
Troubleshooting & Care
Fixing Intonation Issues
Intonation problems plague even seasoned players, often manifesting as "the gap": an open D string may ring accurate, but when fretted at the 12th fret, it sounds a half-step sharp or flat. This mismatch arises from three core issues: nut height inconsistencies, fret wire wear, or string tension variance across tunings (a critical pitfall in alternate tunings like DADGAD, where 1st and 4th strings share octave intervals).
Diagnosis Protocol- Octave Test: Pluck the 12th fret of the 6th string (D in Drop D) against the open 6th string. If they align, intonation is stable—otherwise, fret wear or nut irregularities are suspects.
- String-Gauge Check: In low tunings (Drop C# or C), a mismatched gauge (e.g., 0.11s on a 6th string designed for 16th notes) forces unequal tension. Lighter strings stretch faster, causing notes to "pull" sharp; heavier strings can create uneven micro-instructions on the 12th fret.
- Nut Adjustment: If the 1st string’s nut (or 6th string’s nut in DADGAD) is uneven, file it with 400-grit sandpaper, tilting the slot slightly toward the fret where intonation fails. For example, if a Drop B string’s fretted 12th fret is flat, widen the nut slot by 0.2mm to relax tension.
- Fret Equalization: Use a 12th-fret reference (e.g., a 24-fret scale’s 12th fret ≡ octave of the open string). If a fret buzzes at 7th, 12th, or 19th, regrade (dress) it with a crown file. For graphite-laden fretboard, use fine emery paper to remove uneven wear.
- DADGAD Unison Drone: When 1st (D) and 6th (D) strings are in octave, a 0.05mm fret unevenness on the 6th string’s 7th fret (A) can create "drone flutter." Use a stroboscope tuner to pinpoint the discrepancy: if D-A chord at 7th fret rings flat, add 9Hz via the sustain pedal on the 1st string’s 5th fret for compensation.
- Post-Practices Check: After 45 minutes of Drop D power-chord strumming, re-intonate the 6th string at the 2nd fret (A) against the 5th string’s open A. If they differ by 20Hz, loosen the 6th string’s B note by 0.5mm at the nut for equilibrium.
Preventing String Breakage
Alternate tunings impose radical tension shifts on strings, turning "just enough tension" into catastrophic failure. A 12th fret in DADGAD requires 30% more tension than standard D5 tuning, stressing the headstock, tuning machine gears, and string wrapping points (the "winding zone").
Proactive Measures- Gauge Matching:
- Drop C tuning (6th=C): Use light-medium strings (0.12–0.56) for flexibility—Snark ST-8 tuner tests show 0.12s retain 10% more octave stability than 0.13s (measured via 1st harmonic decay at 120Hz).
- Low-DADGBE: 6th string tension peaks at 1,200g (vs. 600g in Standard E).
- Open-G-Drop-D: 6th D (0.13) + 5th G (0.11) = 25% higher break risk than balanced DADGAD (0.11s all).
- String Installation & Wrapping
- Headstock Winding: Wrap the 6th string in 1.5× standard turns (vs. 2× for Standard) in exotic tunings to prevent "slip" under tension. Use a 0.5mm thick string winder insert for precision.
- Butterfly Wrapping Technique: For 10th-fret DADGAD 2nd string (A), wind each wrap outside the previous mark, creating angular tension that resists breakage under 1,500g load (measured via a string tension gauge).
Test for impending failure by gently pulling the 6th string at the 12th fret (Drop D): if it deflects >2mm without breaking, replace strings. For "sweat-swept" strings (oiled hands), use a microfiber cloth over the 1st–6th strings’ surfaces before tuning to reduce friction-induced fraying.
Long-Term Alternate Tuning Maintenance
Constantly switching between Standard and Drop D/EADGBE creates fretted metal fatigue. Over time, truss rods twist, saddles warp, and strings memory-reset, degrading long-term tuning retention.
Preservation Best Practices- Truss Rod Calibration: In DADGAD (D-A-D-G-A-D), the 3rd string (G) under extreme tension can warp the neck by +0.005mm over 30 days. Use a truss rod wrench to adjust by 0.001mm increments weekly, monitoring with a straightedge and string displacement (neck "bow" ≤0.01mm).
- Saddle Retension: After 20 hours of DADGAD strumming, the 1st string saddle (D) often shifts 0.2mm forward. Re-glue with E6 glue for 12 hours, then re-tune the 1st string open (D) at 146.83Hz.
Invest in a tuning-locking case to prevent string twists after storage (e.g., 24-hour Drop C sessions):
- Use a peg winder to set the 6th string at 120Hz (Drop C) and lock tension with elastic band "saddles" before closing the case.
- Label cases with the next scheduled tuning session (e.g., "Tune DADGAD 20240915" > "Reset at 15–20°F").
Advanced Custom Tunings
Designing Custom Tunings
Custom tunings are not random; they’re intent-driven systems—a musician might crave a "shadowy D" for doom metal, a "sunlight G#" for dream-pop, or a "tribal 5ths" for avant-garde folk. This starts with defining tonal goals and translating them into interval ratios.
Creating Your Signature Tuning- Keynote & Narrative: For "Doom-Ethereal" tuning (D—low sub, A—mids, B—highs), set the 6th string as the root tone (D1:146.83Hz). Then map harmonic intervals to the "emotional arc" of the song—e.g., 2nd string at A2 (110Hz, 5:4 ratio above D) for melancholic overtones, 3rd string at G3 (196Hz, 3:2 ratio below A) for gothic depth.
- Chord Trial Blueprint: Test triads in the new tuning to ensure directionality: D (Open), A (5-4-3), G (4-3-2) → if G3 (196Hz) feels "too bright," lower the 3rd string by a comma (≈20Hz) for a "weeping G"; this microadjustment becomes the tuning’s "secret sauce."
- Black Metal Drone-Tuning: 6th=D♭ (138.59Hz), 5th=A♭ (110Hz), 4th=D♭ (146.83Hz) (octave offset), 3rd=F (116.54Hz), 2nd=B♭ (104.60Hz), 1st=D♭ (293.66Hz). This "dissonant fog" was crafted for Emperor’s "Inno a Satana" to eliminate harmonic clarity, replacing it with spectral dread.
Using Math & Ratios for Custom Tunings
Music is math—custom tunings thrive on rational intervals (2:1 octaves, 3:2 fifths) to avoid equal temperament’s "beaten notes." By anchoring ratios, you create organic, "voice-like" tunings that resist the mechanical quality of 12-TET.
Just Intonation Fundamentals- Key Ratio Triad: 2:1 (octave), 3:2 (perfect 5th) and 5:4 (major 3rd) form the "bridge" between standard and custom. For a 6th string G0 (199.95Hz), a 3:2 ratio (5th below G) gives 299.93Hz (D), and a 5:4 ratio (major 3rd) provides 249.94Hz (A).
- Fibonacci Tuning: A 7-string tuning (D–A–D–G–B–E–A) uses Fibonacci sequence intervals: 2, 3, 5, 8… For 6th string D (146.83Hz), 5th string A (110Hz) (3:2), 4th string D (293.66Hz) (2:1), 3rd string G (196Hz) (3:2), 2nd string B (246.94Hz) (5:4), 1st string E (493.88Hz) (2:1). This 3-5-2-3-5-2 ratio creates a self-sustaining harmonic cycle.
Tension (T) = (mass per unit length) × (vibration velocity)². For a custom 6-string tuning where the 6th string’s tension must be 1.2× the 1st string’s, use:
- T6 = T1 × (1.2) = (μ × v1²) × 1.2.
By measuring string diameter (μ) and tuning frequency (v), you can solve for optimal gauge: μ = (T / v²), ensuring no string exceeds its maximum tensile strength (e.g., nickel strings max out at 1,200g, per D’Addario’s tension data sheet).
Digital Tools for Custom Tuning
Modern technology transforms "tuning experimentation" from trial-and-error to precision engineering. Tools now let you build, test, and save tunings while gigging, with some platforms even simulating string breakage to optimize your setlist safeguards.
Hardware Tools- GuitarLab 3.0: Import a custom tuning via CSV (e.g., [146.83, 110, 146.83, 196, 220, 293.66] for DADGAD), then test strummed chord progressions with its "tension calculator" feature, warning you of strings exceeding 1,200g load.
- Korg Pitchblack Custom: A clip-on tuner with "microtonal mode" (0.01Hz sensitivity) for DADGAD 1st string adjustment (D at 146.83Hz vs. adjacent 0.02Hz difference in custom harmonics).
- PureTuning App 2.0: Custom ratio generator where you input "5th=3:2, 3rd=5:4, 2nd=2:1" and it spits out note frequencies (e.g., 2nd string A (110Hz) becomes 110×(3/2) = 165Hz for a triad).
- DAW Integration: In Ableton Live, use "Custom Tuning Track" to assign a MIDI CC to transpose a DADGAD chord and have your guitar tuner automatically adjust—this bridges the gap between virtual and physical strings, ideal for studio experimentation.
- 30-Day Tuning Journal: Program your guitar to save 10 custom tunings in a loop (Drop D, Open E, DADGAD, plus 7 others of your design). Each night, log string breakage points, tension variances, and emotional responses (e.g., "Tuning B3 feels 'anxious'—too sharp 2nd string") to refine ratios.
- Field Test: Take your custom tuning to a band practice, use a voice memo app to record a 1-minute chord progression, then analyze with a spectrogram—any "hissing" at 200–300Hz indicates your ratio’s been miscalculated.
By treating your tuning like a musical blueprint, you move beyond "guessing" to designing—turning a guitar into a signature instrument rather than a vessel for standard scales. Whether you’re correcting intonation with a 0.01mm file or mathematically crafting a 3:2:5 ratio tuning, the result is the same: your hands, strings, and ear co-create something no other instrument (or player) can replicate.
