|This page in a nutshell: When describing the tuning of a stringed instrument:
In articles on stringed instruments and related topics, information on the tuning of the strings is very often included. The formatting of this information raises some surprisingly tricky issues, as the conventions adopted elsewhere are not terribly consistent.
The listing of strings starting nearest the player, the numbering starting furthest away, and the listing of the gauges of string sets in the order of numbering, are all well-established conventions, applicable to all stringed instruments.
This is somewhat inconsistent and confuses many, but Wikipedia is not in the position to change these conventions, and arguably would be involved in advocacy were we to try. And the other problem would be, which to change? The listing of the strings of a guitar say, from lowest to highest, left to right, follows the natural and established pattern of any guitar chord chart. On the other hand, the numbering is used in every guitar method, and follows naturally from tablature. So changing either presents an enormous set of problems, and it is not clear which is the smaller set. Some proponents of change argue one way, some the other.
The listing of string gauges in Wikipedia articles is relatively rare when compared to tunings, but when it occurs it compounds the problem. Most if not all string manufacturers list their string sets starting with the first string, and this convention is generally followed elsewhere.
Perhaps not surprisingly, there is no consistent convention for the listing of strings in sequence on the music staff, some following the convention of following the order in which the string tunings are normally listed, others the order in which they are numbered.
Strings are listed starting with the string nearest the player.
Depending on the context, sometimes it is sufficient merely to name the notes, as in E–A–D–G–B–E for the guitar. The notes should be named by uppercase letters, and separated by dashes. Sharp and flat signs are placed immediately after the note name, for example B♭ or F♯, as indicated by Wikipedia:Manual of Style (music)#Accidentals.
If the octave is also to be indicated, use either Helmholtz pitch notation, as in E–A–d–g–b–e′ for the guitar, or scientific pitch notation, as in E2–A2–D3–G3–B3–E4. Although the expert will instantly recognise either of these for what it is, for the benefit of the general reader a link should be provided to the Wikipedia article on whichever notation is used. Either notation is equally acceptable, but within a single article one should be chosen and then used consistently, similarly to American versus British English.
The subprime symbol required for octaves below middle C in Helmholtz notation can be produced by
<sub><small>I</small></sub> which produces I, for example the C below middle C is CI and the C an octave below that is CII.
In the case of coursed instruments such as the twelve-string guitar, courses should be separated by dashes, and string notes adjacent, so the twelve-string guitar tuned to octave G tuning is eE–aA–d′d–g′g–bb–e′e′ in Helmholtz notation.
Non-standard notations that may be confused with either Helmholtz or scientific pitch notation should be avoided. For example, the twelve-string unison and octave G tunings are sometimes given as eE–aA–dD–GG–BB–EE and eE–aA–dD–gG–BB–EE respectively (or many, many other variations of this). It is far better to use a standard, formal notation.
Strings are numbered starting with the string furthest from the player. All strings are numbered, so for example the string closest to the player of a twelve-string guitar is always string twelve, and never "string six secondary" or similar constructions.
In the context of instruments that possess at least one multi-string course, a single string normally played on its own may also be called a course. Courses should be numbered if necessary in the same way as individual strings, starting with the course furthest from the player, thus a twelve-string guitar has courses numbered from one to six, while a nine-string baroque guitar has courses numbered from one to five.
It can be tricky. For example, the octave string of the sixth course of a twelve-string guitar is most commonly string twelve, but in the case of the Rickenbacker 360/12 it is string eleven, because of the unusual standard tuning of this particular (and very important) guitar model. An article that referred particularly to the octave string of this pair and applied to all twelve-string guitars would need to be very carefully worded.
Use the simplest wording or numbering that is both precise and accurate. A person reading about a six-string guitar doesn't need to be told about courses.
String gauges are always listed in the order in which the strings are conventionally numbered, rather than the order in which the pitches are conventionally listed, so for example a typical light set for electric guitar would be .009-.011-.016-.024w-.032w-.042w.
This ordering may lead to confusing inconsistency within an article, if string pitches and gauges are listed in the same article. One way around this is to use a table. Another is to insert a phrase such as "lowest to highest" adjacent to the pitch listing; The order in the case of string gauges is relatively obvious. A third is to list both pitch and gauge together, such as .009(E)-.011(B)-.016(G)-.024w(D)-.032w(A)-.042w(E).
But the best solution is a table, listing string number, string gauge and pitch or pitch range as three rows or three columns. Either orientation can work, and either order, but within any article, it's best to be consistent. Choose an order and orientation and stick to it.
If in doubt, the recommended orientation is to have the string number as the leftmost column, and the first string as the top row. This avoids having either order across the page, and so is consistent with either convention for listing pitches in music notation, and with listing either string pitches or gauges conventionally.
The main problem with this format is that it may lead to narrow, tall tables. It may be better to use a different format for article appearance. On the other hand, bear in mind that other readers have different browsers and screen sizes to yours. The recommended format works acceptably in most cases.
Sometimes there may be more than three things to list, for example if there are several alternative tunings for a single stringing, or several common gauges of string. The recommended format copes well with these cases, and with combining what would otherwise be several tables into one.
Gauges are given in imperial measure, either in inches or in thou. Within a single article, either inch measure or thou measure should be used consistently. In either case the unit may be omitted, and again either way this should be consistent throughout the article.
Often only the top and bottom gauges are given. In this case the top string is listed first, as in the .017-.095w string set for the baritone guitar.
Wound strings are shown by the suffix w added to the gauge. For example, a wound string of 32 thou diameter may be called 32w or .032w depending on whether thou or inch measure is used in the article.
If all strings mentioned in an article are wound, for example on a bass guitar, the w suffix may be omitted so long as this is consistently done throughout the article, but this is not generally recommended. If any string gauges within the article include plain (unwound) strings, then the w suffix should be shown for all wound strings.

The most common way to represent the string tunings of many instruments is by a chord with all strings open.
For instruments with many closely tuned strings, this is impractical, and for those with reentrant tunings it is positively misleading, so an arpeggio style may be used instead, spreading the string tunings. Recognising this, some writers prefer to use arpeggio style for all instruments. An issue then arises, should the strings be listed in the order in which they are conventionally listed in the text, or in the order in which they conventionally numbered?
Either order is acceptable, provided:
The pitch should be indicated by a note shape with a solid body but no tail, indicating that the duration of the note is unspecified.
There are four closely related terms that should be used with care:
In many cases several related tunings share a common name, either for different instruments or the same one. For example, open G tuning has a different meaning depending on whether the instrument is a steel guitar or a resonator guitar. C6 tuning can mean any of four common tunings just for six-string lap steel guitar, as well as others for other instruments.
