F13 Chord On The Guitar – Diagrams, Finger Positions and Theory

The F13 chord contains the notes F, A, C, Eb and D. It is produced by taking the 1 (root), 3, 5, b7 and 13 of the F Major scale. It is essentially an F dominant 7 chord with an added 13. Here’s how to play it.

Some Quick F13 Chord Theory

  • The F13 chord contains the notes 1, 3, 5, b7 and 13
  • The ’13 note’ is the same as the ‘6 note’ of the scale, but the 13 implies that the ‘b7 note’ is also included.
  • The F13 chord is made up of F, A, C, Eb and D.
  • The 9th of the scale is sometimes included, but because guitarists have a limited number of strings available, it is often left out.
  • The F mixolydian mode is often used for soloing over F13.
  • F13 is essentially an F7 chord, with an added note (13).

Standard F13 Shape

The standard F13 shape is played with the root note on the sixth string. Although this uses all four fingers and can seem difficult to begin with, it can quickly become a comfortable shape, because there is no barring involved, and none of the fingers need to stretch.

This is the standard shape that most guitarists default to when they think of the F13 chord.

Easy F13 shape

The easy version of the F13 chord is played on the 2nd, 3rd and 4th strings. It’s actually a very easy shape, because each of the first three fingers gets its own fret (and string), forming a diagonal pattern, as seen below).

Keep in mind that with this version, the root note and the 5th of the chord are omitted. However, this is still a legitimate 13th chord, because in guitar land, it’s very common (and often necessary) to leave out chord tones.

How to use the F13 Chord in a Musical Context

The easiest way to start using the F13 chord is use it in place of the F dominant 7 chord (F7). In almost all contexts, the F13 will work well in place of the F7 chord and will add an interesting colour. Consider the following chord progression, which is a ii V I in Bb Major.

  • Gm7 – F7 – Bb Maj 7 – Bb Maj 7

Try playing the chord progression above. Once you are familiar with the sound of the chord progression, try substituting in the F13 chord for the F7 chord, like this:

  • Gm7 – F13 – Bb Maj 7 – Bb Maj 7

This is just one example. Another useful exercise is to play the 12-Bar-Blues in the key of F and use 13th chords instead of dominant 7 chords.

Can F13 be Played as a Barre Chord?

Although some of the possible F13 chord shapes contain barred fingers (usually half barres), the 13th chord in general is not really a barre chord. The most common way to play the F13 chord does not use any barring. However, we can look at the root 6 and root 5 versions of the F13 chord. This can be helpful, because most guitarists use the sixth and fifth strings of the guitar as navigational strings, when locating chords. By learning the root 6 and root 5 versions of the F13 chord, they can be grouped more easily with other root 6 and root 5 chords (that have F as the root).

What’s the Difference Between F13 and F6?

The ’13’ in the F13 chord refers to the 13th note of the Major scale. The 13th note of the Major scale is simply the 6th note of the scale, up one octave. We refer to it as the 13 (instead of 6) because generally speaking, the 13th note is played in a higher octave (although this is a very general guideline and not a rule). Therefore, people sometimes question whether F6 and F13 are the same chord. The answer is that they are actually not the same chord. The F13 chord contains the b7 (Eb), whereas the F6 chord does not contain the b7:

  • F13 = F, A, C, Eb, D
  • F6 = F, A, C, D

The F6 chord is also used as a substitute for the F Major 7 chord, whereas the F13 chord is used as a substitute for the F dominant 7 chord.

Funky Versions of F13 (3 shapes using only 4 strings)

Although the 13th chord is often associated with Jazz, it is also used prolifically in the Funk and RnB styles. Often, when used in these styles, the chord voicings are isolated to the first four strings of the guitar, with allows for a lighter, less bass-heavy sound, more suitable for funk strumming.

Here are three F13 shapes which use the first four strings of the guitar.

Does F13 Contain the 9 (G)?

Technically speaking, the F13 contains the 9th of the scale (G) as well as the 13th:

  • 1 – 3 – 5 – b7 – 9 – 13

Piano players are likely to add the 9 in the chord when they come across F13. However, as guitarists, we rarely play all of the notes in a chord, especially with extension chords. Therefore, most of the F13th chord voicings that guitarists play, don’t actually include the G note (which is the 9). Keep in mind that the 9 will generally always compliment the F13 chord, so it can be included, but often it is not.

Here are the two most common F13 chords with the 9 included:

Which Scales can be Used Over the F13 Chord?

  • F Mixolydian mode – this is the standard scale (mode) for F dominant 7 chords (including F13).
  • F Major Blues Scale – using this scale will add a Blues flavour to the F13 chord.
  • F Major pentatonic scale – this is an easy scale to use with F13, but it does not contain the b7.
  • F lydian dominant – this scale (mode) is especially popular in a Jazz context.

Which Key Does F13 Belong to?

Because the F13 chord can function as a substitute for the F7 chord, we can say that it belongs in the key of Bb:

F13 Chord Substitutions

F13 itself can be used as a substitute for the F7 chord. This also means that in many contexts, F13 will work well as a substitute for other F dominant 7 chords with extensions and vice versa:
