Alternate Guitar Tunings Guide: Drop D, DADGAD, and Open Tunings

Why retune at all?

Standard tuning, EADGBE low to high, is a compromise designed to make as many chord shapes as possible reachable with minimal stretching. It's an excellent general-purpose tuning, but it isn't the only option, and for certain sounds it isn't even the best one. Alternate tunings trade some of that general-purpose flexibility for specific advantages: bigger open chords, easier drones, lower and heavier riffs, or chord voicings that are simply impossible to finger in standard tuning.

The tradeoff is real: every alternate tuning means relearning where notes and chords live on the neck, and most chord shapes you already know stop working as soon as you retune. Whether that tradeoff is worth it depends on what you're trying to get out of the guitar in a given song or session.

Drop D: the easiest entry point

Drop D changes only one string: the low E is tuned down a whole step to D, giving you D-A-D-G-B-E. Everything else stays exactly as it was in standard tuning, which makes Drop D by far the least disruptive alternate tuning to switch into and out of.

The payoff is a one-finger power chord. Barring all three low strings (D-A-D) on any fret gives you a full, heavy power chord with a single finger, which is why Drop D is a staple in rock and metal rhythm playing. It also adds a lower D root note that simply isn't available in standard tuning, useful for riffs that want to dip below the open low E.

DADGAD: the modal drone tuning

DADGAD, low to high D-A-D-G-A-D, originated in Celtic and British folk fingerstyle playing and has since spread into a wide range of acoustic and ambient styles. With this tuning, strumming all six open strings produces a Dsus4 chord rather than a clashing jumble, which means open strings can ring freely under a melody without needing to be muted.

What makes DADGAD distinctive is its modal, slightly ambiguous quality, it doesn't commit strongly to major or minor the way standard-tuning chords do. That ambiguity is exactly why it's popular for instrumental and atmospheric fingerstyle pieces: it leaves more harmonic space for a melody to move through.

Open G: built for slide

Open G, D-G-D-G-B-D, tunes the open strings to a G major chord. Strum any fret across all six strings and you get a major chord at that fret, which is exactly what makes it the tuning of choice for slide guitar: a slide can be laid flat across the strings at any fret and produce a clean chord with no fretting hand shaping required.

Open G has deep roots in blues and roots-rock slide playing, and it remains the most common open tuning for that style today. Even without a slide, Open G is useful for big, ringing strummed chords using just one finger across multiple frets.

Open D and Open E: the same idea, different keys

Open D (D-A-D-F#-A-D) and Open E (E-B-E-G#-B-E) work on the same principle as Open G, the open strings form a major chord, but centered on a different root. Open E in particular puts more tension on the strings since several are tuned up rather than down, which some players avoid for fear of breaking a string, while others prefer for the slightly brighter, tighter tone it produces.

Choosing between Open D, Open G, and Open E for a slide piece often comes down to which key the song needs and which tuning's overall string tension feels best on a particular guitar.

What actually changes when you retune

The biggest adjustment with any alternate tuning isn't physical, it's mental: your existing map of "this shape equals this chord" stops applying. A G chord shape that works in standard tuning will produce a completely different, often dissonant, result in DADGAD or Open G. This is why switching tunings mid-set requires either a dedicated guitar or a few minutes of retuning, and why most guitarists treat alternate-tuning songs as a separate skill set rather than an extension of standard-tuning playing.

On the upside, many open and modal tunings make certain chord voicings dramatically easier. A full, ringing chord that would require an awkward four-finger stretch in standard tuning might be a simple one-finger barre in an open tuning.

String tension and gauge across different tunings

Every string has a tension range it's designed for, and moving a tuning up or down shifts that string outside its normal range in one direction or the other. Drop D and DADGAD lower overall tension slightly since most or all strings drop in pitch, which can make strings feel a touch looser and slightly more prone to buzzing if the action is already low. Open E is the opposite case: several strings are tuned up from standard pitch, raising tension across the neck, which is why some players either switch to a slightly heavier string gauge for Open E or choose Open D instead, which reaches a similar sound with less net tension increase.

If you plan to keep a guitar in a higher-tension open tuning long-term rather than just for one song, it's worth having a tech check the neck relief and action afterward. A neck set up and adjusted for standard tuning tension isn't necessarily optimized for a tuning that pulls noticeably harder or softer on the strings, and persistent extra tension over weeks or months is the kind of change a proper setup accounts for.

Nashville tuning: a different kind of alternate tuning

Nashville tuning, also called high-strung tuning, works differently from the others on this list. Instead of changing which notes the strings are tuned to, it replaces the bottom four strings with the thinner, higher-octave strings from a 12-string guitar set and tunes them an octave above where they'd normally sit, while the top two strings stay the same. The result is a shimmering, jangly, almost chime-like version of ordinary chord shapes, since you're playing the same chords you already know, just with four of the six strings ringing an octave higher than usual.

Because the chord shapes themselves don't change, Nashville tuning doesn't require relearning fingerings the way Drop D or an open tuning does. Its main use is in the studio, layered underneath a normally tuned rhythm guitar to add sparkle and width to a chord progression without doubling the same octave range twice.

Finding your way around an unfamiliar tuning

Rather than memorizing a full chord chart for a new tuning from scratch, it's usually faster to start from what the open strings already give you. Play all six strings open and listen to what chord, if any, it forms, that's your reference point. From there, barring straight across all six strings at any fret moves that same chord up in pitch without changing its shape, which is true in any tuning, open or modal.

Once the open-position and barred-across-all-strings shapes are familiar, look for two- and three-string partial shapes near the open position that produce other useful chords, these are usually the fastest wins in a new tuning and don't require full six-string barres. Treat learning a new tuning the way you'd treat learning a new instrument's basics: a small vocabulary of two or three shapes is enough to start playing real music, with more shapes added as you need them.

Common mistakes when switching tunings

The most common mistake is retuning one string and assuming the rest are unaffected. Loosening or tightening any string changes the net tension pulling on the neck, which can shift the pitch of the other strings slightly, especially noticeable on guitars with a floating tremolo bridge, where changing one string's tension tips the whole bridge and detunes every other string a small amount. After retuning for an alternate tuning, it's worth rechecking all six strings, not just the ones you intentionally changed.

A second common mistake is retuning quickly by ear without a tuner when moving into a tuning with significantly higher tension, like Open E. Bringing a string up in pitch too fast risks snapping it, especially with older strings that have already been stretched and worked at their current tension for a while. Tuning up gradually, and re-stretching the string by hand partway through, reduces that risk considerably.

Combining alternate tunings with a capo

A capo works exactly the same way on an alternate tuning as it does on standard tuning: it raises the pitch of every string by one semitone per fret, regardless of what those strings were tuned to underneath it. This means you can keep the open, droning character of DADGAD or the slide-friendly major chord of Open G while still landing on whatever key a song actually needs, by simply adding a capo on top of the alternate tuning.

This combination, alternate tuning plus capo, is common in folk and singer-songwriter contexts where the open-string sound is part of the arrangement but the song needs to sit in a specific vocal key.

Is it worth switching?

For a single song with a distinctive alternate-tuning riff, yes, the unique sound is usually the whole point. For general playing and jamming with others, standard tuning remains the most practical choice simply because it's what everyone else expects and what most chord charts assume. A reasonable approach is to keep one guitar in standard tuning for everyday playing and treat alternate tunings as a deliberate choice for specific songs or recording sessions where the sound justifies the retuning time.
