What notes are in the Cm7 chord?
The Cm7 chord is a minor 7th chord, and its notes are fixed: C, D#, G, A#. 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 Cm7 at a glance. On the ukulele, start with the first voicing above and listen for the notes C, D#, G, A# in Cm7.
| Note | Interval |
|---|---|
| C | Root |
| D# | b3 |
| G | 5 |
| A# | b7 |
The root is C, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Cm7 are b3, 5, b7. Once you know the intervals, you can build Cm7 from any root by counting the same semitone steps, which is how the chord works in every key. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
Cm7 sounds smooth, mellow and understated — the minor 7th chord is the most relaxed-sounding seventh chord there is. That character comes straight from the intervals above, not from the instrument: the same notes on piano, guitar or ukulele carry the same colour, even though the voicing changes. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
Comparing Cm7 with its closest relatives helps to fix it in your ear. In short, minor 7th against dominant 7th: both have the flattened 7th A#, but Cm7 has the minor 3rd D# while the dominant 7th has the major 3rd E. Hearing the comparison matters more than reading it: play Cm7, then play the chord it is compared with above, and let your ear find the note that changed. On the ukulele, start with the first voicing above and listen for the notes C, D#, G, A# in Cm7.
How to play Cm7 on ukulele
On the ukulele, Cm7 has 3 voicings in the data below, and each one uses the same notes — C, D#, G, A# — in a different place on the neck. There are 3 voicings listed for Cm7 on the ukulele; learn the first, then add the others as you need them. 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 movable voicing is the voicing to learn if you want Cm7 in around fret 3: G string at fret 5 (ring finger); C string at fret 3 (index finger); E string at fret 6 (little finger); A string at fret 3 (middle finger). The stretch is the challenge: the fretted notes span from fret 3 to fret 6, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Cm7 — C, D#, G, A# — sounds, with no buzz and no accidental open string.
The barre chord puts Cm7 in around fret 1: G string at fret 3 (index finger); C string at fret 3 (index finger); E string at fret 3 (index finger); A string at fret 3 (index finger). It barres across strings 1 to 4 at fret 3 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 4 evenly at fret 3, 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 Cm7 — C, D#, G, A# — sounds, with no buzz and no accidental open string.
The movable voicing puts Cm7 in around fret 3: G string at fret 5 (middle finger); C string at fret 3 (index finger); E string at fret 6 (ring finger); A string at fret 6 (ring finger). The stretch is the challenge: the fretted notes span from fret 3 to fret 6, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Cm7 — C, D#, G, A# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Cm7 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 Cm7 up the neck to any key without changing the shape. When you change chords, pick the voicing of Cm7 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Cm7 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
A short practice routine for Cm7 on the ukulele: 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 Ukulele Chord Finder to see the diagram for Cm7 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 Cm7 sound wrong on the ukulele, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Losing the 7th in a thick voicing. A# is easy to bury under the root and 5th. Voice the chord so the 7th rings, or the chord collapses into a plain minor triad. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
Rushing ii–V–I. Cm7 usually leads to a dominant chord and then home. Practise the three-chord move slowly so each chord gets its full beat. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on Cm7 pulls the notes sharp and tires the hand. Use the lightest touch that gives a clean note, and keep your fingers close to the frets. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
Playing the major 3rd. If the 3rd is E instead of D#, the chord becomes a dominant 7th. Keep the 3rd minor — it is what makes this chord mellow rather than bluesy. On the ukulele, the movable voicing voicing is the place to hear it in Cm7.
Where Cm7 is used
Cm7 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 D# major, the key of G# major, the key of A# major. the ii in ii–V–I, the most common progression in jazz. 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 Cm7 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, start with the first voicing above and listen for the notes C, D#, G, A# in Cm7.
Because Cm7 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 Cm7 in a progression in any key and hear how it connects to the chords around it. On the ukulele, start with the first voicing above and listen for the notes C, D#, G, A# in Cm7.
The same chord on other instruments is covered in Cm7 on guitar, Cm7 on piano, Cm7 on bass, and the scales that fit over it are the C major scale and the C minor pentatonic scale. Learning Cm7 on the ukulele and then checking it on another instrument is one of the best ways to fix the notes — C, D#, G, A# — in your memory, because the notes stay the same while everything else changes.
Practising Cm7
A short worked example makes Cm7 concrete. Play the four-chord progression F – C – Dm – A# in F major, the key Cm7 most often resolves toward: F – C – Dm – A#. Play each chord for one bar at a slow tempo, and listen to how Cm7 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 Cm7 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the ukulele, the movable voicing of Cm7 puts those notes under your fingers in the order the fingering lists them.
For a second exercise, play Cm7 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 Cm7 is built for when it acts as a dominant. Finish by playing Cm7 on its own, slowly, and naming each note out loud as you play it: C, D#, G, A#. 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 ukulele, start with the first voicing above and listen for the notes C, D#, G, A# in Cm7.
