The C#m11 guitar chord is a minor 11th chord with the notes C#, E, G#, B, D#, F#. Its first guitar voicing is the open position: low E string muted; A string at fret 4 (middle finger); D string at fret 4 (middle finger); G string at fret 1 (index finger); B string open; high e string open. Whether you are learning it for the first time or checking a voicing, this page has the notes, the guitar fingerings, the inversions and alternatives, and the progressions it appears in.
What notes are in the C#m11 chord?
The C#m11 chord is a minor 11th chord, and its notes are fixed: C#, E, G#, B, D#, F#. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root C#, so you can see the structure of C#m11 at a glance. On the guitar, start with the first voicing above and listen for the notes C#, E, G#, B, D#, F# in C#m11.
| Note | Interval |
|---|---|
| C# | Root |
| E | b3 |
| G# | 5 |
| B | b7 |
| D# | 9 |
| F# | 11 |
The root is C#, the note the chord is named after and the note your ear hears as home. Above it, the intervals in C#m11 are b3, 5, b7, 9, 11. Once you know the intervals, you can build C#m11 from any root by counting the same semitone steps, which is how the chord works in every key. On the guitar, the notes appear in the order the fingering dictates, but the set of notes never changes.
C#m11 sounds soft and open, a minor chord with the 9th and 11th adding width without tension. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of C#m11 noticeably. On the guitar, the open position of C#m11 puts those notes under your fingers in the order the fingering lists them.
Comparing C#m11 with its closest relatives helps to fix it in your ear. In short, minor 11th against minor 9th: C#m11 adds the 11th F# to the minor 9th chord. The extra note widens the sound without changing the function. Play both chords slowly, one after the other, and notice which note moves. Naming that note out loud while you play is the fastest way to learn the difference. On the guitar, the open position voicing is the place to hear it in C#m11.
How to play C#m11 on guitar
On the guitar, C#m11 has 3 voicings in the data below, and each one uses the same notes — C#, E, G#, B, D#, F# — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
The open position is the voicing to learn if you want C#m11 in open position: low E string muted; A string at fret 4 (middle finger); D string at fret 4 (middle finger); G string at fret 1 (index finger); B string open; high e string open. The challenge here is the muted string: 1 string is marked x, and it needs to stay silent. Let the edge of a fretting finger rest lightly on it — muting by touch, not by pressing. Strum or pluck it slowly first and check that every note in C#m11 — C#, E, G#, B, D#, F# — sounds, with no buzz and no accidental open string.
Another way to play C#m11 is the barre chord, in open position: low E string open; A string at fret 4 (ring finger); D string at fret 1 (index finger); G string at fret 1 (index finger); B string open; high e string at fret 2 (middle finger). It barres across strings 3 to 4 at fret 1 with the index finger. The barre is the hard part: the index finger must press every string from 3 to 4 evenly at fret 1, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in C#m11 — C#, E, G#, B, D#, F# — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want C#m11 in around fret 2: low E string muted; A string at fret 4 (ring finger); D string at fret 2 (index finger); G string at fret 4 (little finger); B string open; high e string at fret 2 (middle finger). The challenge here is the muted string: 1 string is marked x, and it needs to stay silent. Let the edge of a fretting finger rest lightly on it — muting by touch, not by pressing. Strum or pluck it slowly first and check that every note in C#m11 — C#, E, G#, B, D#, F# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of C#m11 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide C#m11 up the neck to any key without changing the shape. When you change chords, pick the voicing of C#m11 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into C#m11 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the guitar, the open position voicing is the place to hear it in C#m11.
A short practice routine for C#m11 on the guitar: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above C# and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits. Use the Guitar Chord Finder to see the diagram for C#m11 while you practise, and the Chord Finder to compare it with the same chord on other instruments.
Common mistakes
These are the mistakes that most often make C#m11 sound wrong on the guitar, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Crowding the voicing. Six notes need space. Drop the 5th (G#) first and spread the rest across octaves. On the guitar, the open position of C#m11 puts those notes under your fingers in the order the fingering lists them.
Losing the 11th. Without F# this is just a minor 9th chord. The 11th is the note that makes it an 11th. On the guitar, start with the first voicing above and listen for the notes C#, E, G#, B, D#, F# in C#m11.
Playing it too fast. C#m11 is a slow chord. At a fast tempo its colour gets lost. On the guitar, the open position voicing is the place to hear it in C#m11.
Barre collapsing on the high strings. In a barre voicing of C#m11, the high strings are the ones that buzz first, because the index finger presses hardest near the thumb. If the top notes of C#m11 sound dead, roll the barring finger slightly toward the fret and press from the arm, not from squeezing the neck. On the guitar, the open position voicing is the place to hear it in C#m11.
Where C#m11 is used
C#m11 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of E major, the key of A major, the key of B major. a minor tonic in jazz and neo-soul, richer than the minor 9th. As a dominant-type chord it also points toward F# major, the key a perfect fourth above C#, which is the tonic it most often resolves to. That is where C#m11 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the guitar, the open position voicing is the place to hear it in C#m11.
Because C#m11 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain C# triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try C#m11 in a progression in any key and hear how it connects to the chords around it. On the guitar, the open position of C#m11 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in C#m11 on piano, C#m11 on ukulele, C#m11 on bass, and the scales that fit over it are the C# major scale and the C# minor pentatonic scale. Learning C#m11 on the guitar and then checking it on another instrument is one of the best ways to fix the notes — C#, E, G#, B, D#, F# — in your memory, because the notes stay the same while everything else changes.
Practising C#m11
A short worked example makes C#m11 concrete. Play the four-chord progression F# – C# – D#m – B in F# major, the key C#m11 most often resolves toward: F# – C# – D#m – B. Play each chord for one bar at a slow tempo, and listen to how C#m11 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on C#m11 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the guitar, start with the first voicing above and listen for the notes C#, E, G#, B, D#, F# in C#m11.
For a second exercise, play C#m11 and then the chord a fourth above C#, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move C#m11 is built for when it acts as a dominant. Finish by playing C#m11 on its own, slowly, and naming each note out loud as you play it: C#, E, G#, B, D#, F#. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the guitar, the open position of C#m11 puts those notes under your fingers in the order the fingering lists them.
