Chords in the Key of C: The 7 Chords, Progressions and Songs

The key of C is where music theory begins. It has no sharps or flats, its scale is simply the white keys on a piano, and its chords are the reference point for almost every chord chart and theory book. On guitar, C is a friendly key too, with one famous catch: the F chord.

This guide covers the seven chords in the key of C, how to play them (including easy ways around F), the progressions you'll use most and how C relates to its sister key, A minor.

The 7 chords in the key of C

The C major scale is C D E F G A B. Building a chord on each note gives:

Number	Chord	Type	Notes
I	C	Major	C E G
ii	Dm	Minor	D F A
iii	Em	Minor	E G B
IV	F	Major	F A C
V	G	Major	G B D
vi	Am	Minor	A C E
vii°	Bdim	Diminished	B D F

The pattern of chord types (major, minor, minor, major, major, minor, diminished) is the same in every major key. That's why the key of C is so useful for learning: once you understand it here, you can apply it to any key.

How to play the chords in C

• C (I): the home chord. Strum from the A string. See the C major chord page.
• Dm (ii): strum the top four strings. It often leads to G.
• Em (iii): two fingers, all six strings.
• F (IV): the small F is shown. The full version is a barre chord; see below for easier options.
• G (V): creates the pull back to C.
• Am (vi): the relative minor of C, and one of its most important chords.
• Bdim (vii°): a tense, unstable chord, used occasionally as a passing chord.

Dealing with the F chord

F is the only hard chord among the main ones in C, and it's in a lot of songs. You have options:

• Fmaj7: no barre at all. It sounds softer than F, but works in most pop and folk songs.
• Small F: a two-string barre on the top four strings. A real F chord, and the best everyday choice.
• Full F: the six-string barre. Worth learning over time.

Our F chord guide has four easier versions and a seven-day plan for the full barre. You can also avoid F entirely with a capo: play the song with G shapes and a capo on the 5th fret, so G, C and D sound as C, F and G.

What each chord does

• C (I) is home base: stable and resolved.
• F (IV) moves away from home with a warm, open feeling.
• G (V) builds tension that resolves back to C. G7 makes the pull even stronger.
• Am (vi) gives a sad or thoughtful color, while sharing two notes with C.
• Dm (ii) usually leads to G. The Dm – G – C move (ii – V – I) is the most common ending in jazz and pop.
• Em (iii) is a softer, less common chord that often leads to F or Am.

Common progressions in C

Progression	Numbers	Feel
C – F – G – C	I – IV – V – I	Classic, folk, rock and roll
C – G – Am – F	I – V – vi – IV	The best-known modern pop progression
C – Am – F – G	I – vi – IV – V	1950s ballads
Am – F – C – G	vi – IV – I – V	Emotional pop and rock
Dm – G – C	ii – V – I	Jazz and song endings
C – Em – F – G	I – iii – IV – V	Gentle, rising

C – G – Am – F and Am – F – C – G are the same four chords starting in different places, and they're behind an enormous number of hit songs. Learn them both. For more patterns, see guitar chord progressions.

Variations that sound great in C

• Cmaj7 for C: dreamy and soft. Just lift your index finger from C.
• Am7 for Am: lift your ring finger from Am for a mellower sound.
• Dm7 for Dm: one barre-like finger on the top two strings, very smooth before G.
• G7 for G: strengthens the pull back to C. Classic in blues, country and older pop.

Our guide to seventh chords explains the different kinds of 7th chord and when to use each.

Songs in the key of C

Many simple melodies are written in C, including traditional pieces like "Twinkle, Twinkle, Little Star" and Beethoven's "Ode to Joy," because C is the reference key in music education. On guitar, plenty of pop and rock songs are played in C or with C shapes and a capo. If a song uses C, F, G and Am, it's very likely in C. For a beginner-friendly list sorted by chords, see easy guitar songs for beginners.

Playing in C with a capo

C shapes are bright and sparkly with a capo. Here's what they turn into:

Capo fret	Sounds in	C – F – G – Am becomes
2	D	D – G – A – Bm
3	E flat	Eb – Ab – Bb – Cm
4	E	E – A – B – C#m
5	F	F – Bb – C – Dm
7	G	G – C – D – Em

That last row is interesting: C shapes with a capo on the 7th fret sound in G, but with a very bright, high sound. Some players use this to add a second guitar part above someone playing ordinary G shapes. Our guide on how to use a capo explains more.

C major and A minor: the same notes

The relative minor of C is A minor. It uses exactly the same seven notes and the same chords; the difference is which chord feels like home. A song that keeps returning to Am, and ends there, is in A minor. Many songs move between the two, which is part of why C – G – Am – F feels both happy and bittersweet. See chords in the key of A minor for the minor side of these chords.

How to practice the key of C

1. Master C, G and Am. Practice C ↔ G and C ↔ Am for a minute each.
2. Add an F you can play. Start with Fmaj7 or the small F. Practice C ↔ F and Am ↔ F.
3. Play C – G – Am – F with four strums per chord, then two.
4. Add Dm. Practice the Dm – G – C ending.
5. Try the 7th chords: Cmaj7, Am7, Dm7 and G7, and notice how they soften or strengthen each chord.

Keep your changes steady with our free metronome, starting around 60 beats per minute.

Next keys to learn

G is the natural next key: it shares four chords with C (C, G, Am and Em) and swaps F, Dm and Bdim for D, Bm and F#dim. Our guide to chords in the key of G covers it, and the keys of D and A come next.

Soloing in the key of C

The C major pentatonic scale (C, D, E, G, A) contains the same notes as the A minor pentatonic scale. That means the most famous scale shape on guitar, the A minor pentatonic box at the 5th fret, works over songs in C too. Over a C chord, try ending phrases on C or E; over Am, end on A. The full C major scale adds F and B. Our guides to the major scale and the minor pentatonic show the shapes.

Common mistakes in the key of C

• A dead high e string on C: your ring or middle finger is touching it. Arch your fingers and keep your thumb low.
• Giving up on songs with F: use Fmaj7 or the small F, or a capo, and keep playing.
• Playing G when the chart says G7: both work, but G7 makes the return to C stronger and is easy to play.
• Strumming all six strings on Dm: start on the D string.

Fretwork's path introduces keys like C and G alongside the chords themselves, so the theory always connects to something you can play. The first two stages are free, no card required.
