The Partial CapoPartial capos have gained considerable popularity in recent years, and for good reason. A partial capo brings remarkable new possibilities to guitar:
Enough talk! Here's an example of the partial capo in action. Listen to this slow, gentle, intermediate level strumming arrangement of an old-time American fiddle tune Sally Coming Though the Rye. A Complete Introduction to Partial RealityMany years ago a friend showed me a unique method of capoing a guitar. Instead of placing the capo across all six strings, he shifted the capo off the 6th string (the lowest string) leaving it uncapoed. The result is shown in the following Partial Drop-D diagram. This is the simplest way to partially capo a guitar, and you don't need anything but a C-clamp style capo, such as a Shubb or Kayser capo:
Capoing less than all strings is generally called partial capoing. The most popular partial capo technique emulates DADGAD tuning, and requires a specially designed partial capo like the Shubb C7B ... or some ingenuity. In the following example the capo depresses the 2nd fret on the 3rd, 4th and 5th strings. If you have a full capo on the guitar, place the partial capo two frets above the full capo:
Various type of Partial Capo techniquesThere are many possible approaches to partial capo. We'll explore four partial capo techniques in this article. Others techniques may be mentioned, but without much follow up. Some partial capo techniques require special capos (not surprisingly called partial capos.) As you see in the following diagram, you can apply the 3-string Shubb C7B capo in at least three different ways. So the physical partial capo is but one aspect of a range of partial capo techniques. Here are pictures of several common partial capo techniques:
The first two diagrams show Partial Drop-D: the first using a regular Shubb capo; the next using the "dedicated" Shubb C8B capo, designed specifically as a "Drop-D capo. The next two diagrams show two applications of the Shubb partial capo (Shubb model C7B): Partial DADGAD and Partial G. Then there's the sawed-off approach, where you sacrifice a perfectly good Shubb capo under a hack saw -- just takes a couple of minutes. The result is a Four-string partial DADGAD capo, which provides a dramatically increased DADGAD effect -- the bottom four strings behave exactly like DADGAD! The last example shows the C7B capo in a third technique I call the Stadler Stradler, stumbled upon by Michael Stadler as he says "before I knew any better!" Try playing in C position with this configuration: C, F and G chords. (Furthermore my notes include Partial DBEAAD (aka D Cycle of 4ths), but I've forgotten what it means, so no picture!) Partial SuccessAt first, when capoed to partial Drop-D, I was unable to fully comprehend my guitar's new behavior. Fortunately most of the surprises were pleasant, and I easily worked around the intermittent confusion. Proceeding with only a partial understanding of partial capoing, I spruced up some incomplete and ailing finger-picking arrangements, and quickly transformed many of them into strong, satisfying, well balanced pieces. Additionally I developed a new found affinity for arranging and composing in the key of D. (Here's a piece I wrote using partial Drop-D the working title is Rising Sun. Obviously much can be accomplished by pure experimentation, intuition, and just banging around ... yet with every insight doors open and previous knowledge applies, so I'll do my best here to impart what I've come to understand. Partial ConfusionThere's a critical issue that becomes obvious almost immediately, be it one that's especially difficult to explain or comprehend. Partial capoing causes the characteristics of two separate tunings to mysteriously overlap. You'll get the benefits and limitations of both. I'll remind you of this point many times as we proceed. The trick is in understanding when and why. If you proceed at a rate similar to my initial progress, and if like me, your insights seem half illuminated and dissolve as quickly as they occur, prepare to review the principles regularly. In a nutshell, here's an explanation of the physical side of partial capoing: * NOTE: For many years I had always capoed atop standard tuning. Then one day, in a flash of insight, I created one of my favorite configurations: the Four-String Partial DADGAD (explained below); where I capo over Drop-D tuning: DADGBE. Though I've used this technique for years now, I never seen anyone else do so. Nor have I seen capo over a base tuning other than EADGBE. (Hopefully, in keeping with the best spirit of the Internet, I'll get immediate reports from people who do so, and with dazzling results. Nevertheless, for now, other capo/tuning combinations are simply more than either of us should care to think about. Still, at some point you might want to explore.) More Physical ConsiderationsNote: This section for intellectuals only ... and/or for those with plenty of previous partial capo experience! If you're new to partial capos, please skip this section! Partial A7 : 002020 Partial G: 300033 ... but notice that all the frets must be the same. Multi-fret Partial CaposI don't know if anyone has invented a partial capo that spans two or more frets ... Probably someone ... somewhere. Here's a couple of conceptual examples: It's also possible to partial capo other instruments. For instance, one could partial capo a mandolin so it emulates a fiddle's cross A tuning (AEAE). The capo configuration would be 2200 atop the standard mandolin tuning GDAE. I think I went wild one night with the mandolin capoed 0222. Matters of Intonation Anytime you place a capo on a guitar you invite intonation problems. Partial capoing is no exception, in fact, at times your might have two capos in place, which can exacerbate the issue. Indeed, some capos disturb intonation less than others. I think Shubb capos are pretty good in this respect, but I believe there are greater factors than capo design. The prime aggravating factors are capo placement and tension (i.e. user error.) The moral of the story: Use the minimum pressure required to attain clear tone and buzz-free playing. That said, now consider the following. Capo placement is a greater factor on intonation than capo tension. A capo placed in the midway between the frets will surely cause the guitar to sound sharp. For best results place your capo as close as possible to the fret, even resting part way on the fret (but not so far that the strings sound dull because the capo rubber partially damps them.) When the capo rests partially on the fret (or immediately behind it) its clamping force is halted by the fret, the strings are minimally depressed by the capo, so the capo barely stretches them strings out of tune. If you halt the downward force by capoing at the fret, the amount of capo tension is of secondary concern. Even so, strive to use the minimum adequate pressure. Partial Capo / Full ClarityAnytime you explore tunings, it's smart to look for similarities, otherwise you may end up feeling completely adrift, when actually you're rather close to home. In introducing you to the world of partial capoing, I hope to convey enough understanding so you can immediately able apply your knowledge of standard tuning ... and apply any knowledge you may have of tunings that partial capoing emulate. You'll have the inside scoop on partial capoing if you remember the following four points. The Principles of Partial Reality
This set of rules explain what portion of the guitar behaves like standard tuning, and "what portion behave like the open tuning." I'll return to these axioms numerous times and discuss them in detail as we look at various types of partial capoing. Though the entire secret is fully explained in four simple concepts, they may seem like an intellectual mind game until you work on a few pieces. Read and attempt to understand them; regardless of the result, move on and learn some partial capo material.

Three-string Partial DADGADThis diagram shows the most common 3-string partial capo technique. It's called Partial DADGAD (or Esus). The guitar is tuned standard (EADGBE) and a partial capo is placed on the second fret of the 3rd, 4th and 5th strings. If a guitarist places fingers these frets it produces an E Suspended 4th chord, hence the "Esus" alternate name: This capo position and an Esus4 chord share the same text nomenclature: 022200. NOTE: DADGAD produces a Dsus4 chord. Partial DADGAD shares the same open strings but two frets higher. Notice I didn't say, "It's exactly the same thing." This article is largely about the subtle differences What's Partial DADGAD sound like? Sandy Boys w/ partial capo guitar accompaniment (John Blasquez) Here's another example of a "DADGAD" partial capo accompaniment: |

Three-string Partial DADGAD Standard TerritoryWith a partial capo (like the Shubb C7B) in place, as shown, we're ready jump in. Starting with the familiar, let's look at what's the same. Well, good news ... almost everything! Partial DADGAD emulates DADGAD tuning, yet simultaneously the guitar behaves almost entirely like standard tuning. The green area in the diagram shows the portion of the neck that behaves like standard tuning:. It's everything you can reach even behind the capo! Just stay off the uncapoed open strings! No matter what type of partial capo technique you use, most of your guitar behaves just like standard tuning. Remember, the guitar is not retuned. It is still in standard tuning, so naturally, all fretted notes behave like standard tuning! As with Partial Drop-D and other partial scenarios, all closed fingering scales work like standard tuning. As mentioned, you can even play behind the capo ... but I gotta repeat, stay off those uncapoed open strings. Touch 'em and you shoot through the "worm hole" to the DADGAD parallel universe. The E fingering for standard tuning (022100). This sounds really bad, there's wrong notes on all three uncapoed strings. You're not in Kansas anymore. A minor (002210) has two wrong notes. Try standard tuning's three finger G chord (320003) -- here the open second string sounds wrong. Try a four finger C (332010) makes a very beautiful sound, but it's not a C, it's a Cadd9 chord: 1, 3, 5, 9. |

Three-string Partial DADGAD DADGAD TerritoryWe've just see that most of the guitar behaves like standard tuning. A large portion of the guitar behaves like DADGAD as well. Here we'll explore the DADGAD part of the equation.
That's it. There's nothing else to know. Granted, this information only useful if you know a finger-picking or flat-picking piece in DADGAD. Otherwise you have nothing to experiment with. For those of you who know some DADGAD pieces, play something -- or a portion of something -- that only uses frets on the capoed strings. Chords are a good place to start. Then try a scale ... or a piece you know. Everything works like normal DADGAD on the three capoed strings; you can also used the uncapoed open strings just like open strings in DADGAD. However, when you fret on an uncapoed string, things go awry. Indeed you've exited DADGAD reality, but there is a workaround for fretted notes on the uncapoed strings. Play them two frets lower than you would in DADGAD. Simple concept, but unfortunately it isn't always practical, and you may not want to relearn your pieces just to play them in Partial DADGAD. Whatever the case, it works, and it's a concept that will help you in reworking piece if you choose to do so. What's so great about Partial DADGAD anyway... or DADGAD for that matter? Why do so many people explore it? Why has it become the second or third most popular tuning? For one, you can play a "lazy man's" I-IV-V chord progression with a single finger. I: 000200 With these chord voicings, the guitar drones simultaneously in a pleasingly ethereal way. It's that great sound often heard in backup to Celtic melodies. These easy chords also provide an excellent way of introducing kids to chords and strumming. It shouldn't be hard to find information on chords and tablature for DADGAD on the Internet. Just remember the "principles" when applying this information to partial DADGAD. And bear in mind, just as all DADGAD

Partial Capo Music NotationI don't know of any notation software that writes tablature for partial capo arrangements. If anyone knows of such software, please contact me. Harvey Reid of Third Hand Capo, states, "The largest challenge now facing the partial capo issue these days is the issue of notation, and I have posted an open letter to the guitar industry about this problem." Here's a link to his open letter.

Partial NotationFor clarity, I'll coin the term "partial tablature" when referring to tablature for a partial capoed arrangement. Open is open. No fingers down. These are all written as open strings: zeros on the tablature staff. Fretted NotesFrets are written relative to the partial capo in most pieces. However, in some arrangements guitarists play frets behind the partial capo (I'm referring to the uncapoed strings of course!) In these instances I write the frets relative to the nut .. this usually applies only to a short span of notes. (One could handle the situation differently by using negative numbers -- or zero frets -- but this approach has several drawbacks. It is possible to write all frets relative to the nut, but this hides some important open tuning relationships. ) Since the tablature system may vary back and forth -- relative to the partial capo, then relative to the nut -- some indicator is necessary. Color would suffice, but that would always require color printing or color copying, it and may prove problematic for color blind people. Perhaps changing font style to bold would serve as an adequate indicator. I find that people are perfectly comfortable with a system I devised. Here's an example of my solution. In the tune shown below (entitled Jeff Sturgeon), the black horizontal bar indicates when frets are relative to the nut (or in this case, to a full capo.) A notation package that fully supports Partial Capo tablature would need to address this matter, adjusting frets + or - accordingly. Ideally tablature would be colorized as well, but as mentioned, there needs to be some non-colored method for denoting areas where frets are relative to the nut. When a chord is played, and the chord includes frets below at or below the partial capo -- to avoid confusion -- all notes of the chord should be relative to the nut. In Jeff Sturgeon, an old-time fiddle tune from John Salyer, take note of the 4th fret at the end of measure 2. This could have been written as 2nd fret relative to the partial capo, but the note on the E string must be written relative to the nut -- that or a zero fret which I already recommended against using a symbol such as a zero or negative frets. For various reasons zeros should always indicate open strings. Some people think that frets on the guitar should have a one-to-one relationship with the frets in tablature. For instance, two frets above the Partial DADGAD capo should be written as a four, because indeed it's the forth fret on the guitar. But with this system you can't think DADGAD.
In Jeff Sturgeon, in the first three measure, the frets on the 3rd string vary from 2 to 4, but they actually represent the same spot on the guitar ... just from a different point of view.
