How to read chord charts: symbols, slash chords and bars

To read a chord chart, read each chord symbol in four parts and each line from left to right. The letter is the root (G). A small m makes it minor (Gm); no m means major. A number or word adds or swaps a note (G7, Gmaj7, Gsus4, Gadd9). Anything after a slash is the bass note (G/B). Over a lyric, the chord changes on the syllable printed under it and lasts until the next chord. In a bar chart, each | G | is one bar, and two chords inside one bar share it. Then you turn each symbol into a shape on your instrument, simplifying whatever you can’t play yet.

Below you’ll find a decoder table, a verse and a bar chart worked through beat by beat, the American, Latin and German systems side by side, and a 10-minute reading drill with the free chord progression player.

Chord symbols decoded: the four parts of every chord name

Every chord symbol, however long, is built the same way:

1. Root: a letter from A to G, with # (sharp) or b (flat) if needed. F# and Bb are roots, not extras.
2. Quality: nothing means major. m, min or a dash (–) means minor. dim or ° means diminished, aug or + means augmented.
3. Extensions and changes: numbers and short words after the quality. 7, maj7, 6 and 9 add notes; sus2 and sus4 replace the third; add9 adds a note without a seventh; 5 is a power chord with no third at all.
4. Bass: a slash and a note. D/F# is a D chord with F# as its lowest note.

So F#m7/E reads: root F#, minor, with a seventh, E in the bass. Bbmaj7 reads: root Bb, major (nothing written), with a major seventh. Read it in that order and nothing on a chart is unreadable, only unfamiliar. To hear what each type sounds like and how it’s built, see the guide to types of chords.

Symbol	Also written	Notes (in C)	Can’t play it yet? Play
C	CM, Cmaj	C E G	–
Cm	Cmin, C–	C E♭ G	–
C7	–	C E G B♭	C
Cmaj7	CM7, CΔ, C7M	C E G B	C
Cm7	C–7, Cmin7	C E♭ G B♭	Cm
Csus4 / Csus2	Csus, C4 / C2	C F G / C D G	C, briefly
Cadd9	C(add9), C2	C E G D	C
C6	–	C E G A	C
C9	–	C E G B♭ D	C7
Cdim	C°	C E♭ G♭	keep it
Cm7b5	Cø, Cm7(b5)	C E♭ G♭ B♭	Cdim
Caug	C+	C E G♯	keep it
C5	power chord	C G	C
C/E	slash chord	C E G, E lowest	C
N.C.	no chord	–	stop playing

The last column is the safety net: drop the extension, keep the letter, the m and, if you can, the bass. A song still sounds like itself on the simple version. The exceptions are sus chords, which often carry the hook (let them resolve to the plain chord if you can’t hold them), and dim and aug chords, which are short shapes worth learning because nothing replaces their pull.

Two symbols cause most wrong notes. C7 is not Cmaj7: a plain 7 always means the lower, bluesy seventh (B♭ in C); only maj7, M7 or Δ means the higher one (B). And C9 on an American chart includes the seventh (C7 plus D), while Cadd9 leaves it out. If you want to hear or check any of these, mark the notes in the chord finder and it names the chord and plays it.

Where the chord falls on the lyric

On a chart with lyrics, the first letter of each chord sits over the syllable where the harmony changes. You keep playing that chord until the next one appears. Here’s an original verse in G at 84 BPM, one chord per bar except the last bar:

Key: G · 4/4 · 84 BPM

[Verse]
    G                   D/F#
Six a.m. and the kettle hums,
Em              C
nobody's up but me
       G                           D/F#
I keep writing down the places I'd run
          C       Dsus4 D
if I were half as free

How to read it, line by line:

• “Six” has no chord over it. Words before the first chord of a line are a pickup: you sing them just before the downbeat. The G lands on “a.m.”, and that’s where your hand strikes.
• The G lasts through “and the kettle” and changes to D/F# on “hums”. The chord line never tells you to strum on every word; it tells you when the harmony moves.
• Line 3 starts with a pickup too: “I keep” comes before the G, which lands on “writ-”.
• Dsus4 falls on “free” and D comes after the word. A chord printed past the last syllable changes while you hold the note, here two beats later, as the sus4 resolves.

The same verse written inline, ChordPro style, puts each chord in brackets right before its syllable: Six [G]a.m. and the kettle [D/F#]hums. The rule doesn’t change. Chords over lyrics don’t show how many beats each chord lasts, so check a recording or a bar chart when it matters.

Hear it: open the player with this verse’s chords at 84 BPM (G–D–Em–C–G–D–C–D; it plays a plain D for D/F# and Dsus4) and speak the verse over the loop. Your hand should move exactly on “a.m.”, “hums”, “no-”, “me”, “writ-”, “run”, “half” and “free”. If a chart you downloaded puts a chord one word early or late, trust your ears and move it: crowd-sourced chord sites get alignment wrong all the time.

Bars, beats and repeats: reading a chart without lyrics

Intros, solos and many band charts skip the lyric and use bars. These are the signs you’ll meet:

• | G | D |: one chord per bar, four beats each in 4/4.
• | G D |: two chords in one bar, two beats each.
• | C / D / |: each slash is one beat, so C for two and D for two.
• %: repeat the previous bar.
• |: … :| or x2: play the section again.
• 1. and 2. over the bars: first ending, then skip to the second on the repeat.
• D.S. al Coda: go back to the sign, then jump to the coda at “To Coda”.
• N.C.: no chord. The band stops and the voice or riff goes alone.

A worked example, the intro, chorus and ending of the same song:

[Intro]
| G       | %       | Em      | C   D   |

[Chorus] x2
| C       | G/B     | Am7     | Dsus4 D |
| C       | G/B     | Em  D   | G       |

[Outro]
| C / / / | C / D / | G       | N.C.    |

Count “1, 2, 3, 4” out loud for every bar. The intro is two bars of G (the % repeats it), one of Em, then C for two beats and D for two. The chorus is eight bars played twice, so 16 bars before the outro. In the outro, “C / / /” is one full bar of C written in slashes, “C / D /” splits the next bar, the G rings for a bar and N.C. means everyone stops together. To hear the first chorus line, loop C–G–Am7–D in G; the player plays G for G/B and D for Dsus4 D.

In Nashville studios you may get a number chart instead: chords are scale degrees, a dash marks minor and each number is usually one bar. The first three bars of the intro above read 1 1 6-, in any key.

American, Latin and German chord names side by side

Chord charts don’t use the same alphabet everywhere. US and UK charts, most chord websites and Brazilian cifras use letters. Musicians trained in Spain, Latin America or France often write Do Re Mi. German-speaking charts use letters with two changes: H is the note English calls B, and B means B♭.

Letters (US/UK)	Latin (Do Re Mi)	German
C	Do	C
C# / Db	Do# / Reb	Cis / Des
D	Re	D
Eb	Mib	Es
E	Mi	E
F	Fa	F
F#	Fa#	Fis
G	Sol	G
Ab	Lab	As
A	La	A
Bb	Sib	B
B	Si	H
Am (minor)	Lam	Am, or a in some songbooks

Four traps when a chart crosses a border:

• German B is B♭. A German chart that says “B – F – g – Es” is B♭–F–Gm–E♭ in English letters. “H7” is B7.
• Lowercase can mean minor. Some German songbooks write a for A minor and A for A major.
• Brazilian cifras use numbers differently. C7M is Cmaj7, C4 is Csus4, and in the widely used Cifra Club standard C9 means Cadd9 (no seventh), where an American chart’s C9 includes the seventh. C° there is the four-note diminished seventh.
• Do Re Mi keeps the chord suffixes: Lam7 is Am7, Sol/Si is G/B.

You don’t need to convert by hand. Paste the chart into the chord transposer: it reads letters, German names with H and Do Re Mi, and writes the result in any of the three; leave the key where it is and only the names change. The chord sheet maker also reads Brazilian cifra such as C7M or Am7(9) and shows the whole sheet in the notation you choose.

From the chart to your instrument

Before you play a note, scan the chart and list every different chord. The verse and chorus above use eight: G, D/F#, Em, C, Dsus4, D, Am7 and G/B. Learn the unfamiliar shapes first, then play through.

On guitar:

• Read the capo line first. “Capo 2” means the chord names are shapes: you play a G shape and it sounds as A. The capo chart lists what each shape sounds like on every fret.
• Slash chords: make the chord and put the bass note on the lowest string you play. D/F# is often played with the thumb on the 2nd fret of the low E string (2x0232); G/B is x20033. If you can’t reach it, play the chord without the slash for now.
• Check a shape you’re unsure of by setting its frets in the chord finder. Put your pinky on the 3rd fret of the high E string in a D shape (xx0233) and the finder names it Dsus4.
• Too high to sing? Move the whole chart with the transposer or a capo, not chord by chord.

On piano:

• Right hand plays the chord from the letter up: root, third, fifth, plus the seventh when the symbol has one. For Cmaj7 that’s C–E–G–B; for C7, C–E–G–B♭.
• Left hand plays the root, or the note after the slash. G/B means left hand B, right hand G–B–D.
• Keep the hand close. Move to the nearest version of the next chord instead of jumping to root position every time.

A 10-minute chord chart reading drill

1. Minutes 0–3, say it before you play it. Open the player with Gmaj7–Em–Am7–D7 at 76 BPM. Before each change, say the name aloud (“G major seven, E minor, A minor seven, D seven”) and name its notes from the decoder table.
2. Minutes 3–5, play along. Change chord on beat 1 of each bar. Use the simple version (G, Em, Am, D) the first time round, then the real one.
3. Minutes 5–8, switch systems. Set the player’s chord names to solfège and read the same loop in Do Re Mi: Solmaj7, Mim, Lam7, Re7. Then change the key to D. The loop becomes Dmaj7–Bm–Em7–A7 (Remaj7, Sim, Mim7, La7 on screen); write it on paper the German way, where Bm turns into Hm.
4. Minutes 8–10, add words. Load the verse loop from earlier, speak the kettle verse over it and record one pass on your phone. Listen back for the changes that came late.

Repeat it with a new chart each day for a week. The 11 most common chord progressions give you plenty to read, the guide to singing and playing guitar at the same time picks up where this drill ends, and the lyric and chord sheet guide shows how to write a chart of your own.

Where Zoundroom fits: the decoded chart and your takes in one note

Zoundroom doesn’t read charts for you, doesn’t detect chords in a recording and has no tuner; for naming a shape use the chord finder, and for changing names or keys the transposer. What it does is keep your version of the song together. Each song is a project that holds its recordings, lyrics, notes and files, so once you’ve fixed a downloaded chart (chords on the right syllables, names converted to your system, the capo line clear), paste it into a note in that project and add your own reading notes, such as “Dsus4 = xx0233, lift the pinky on beat 3”. Then record a run-through inside the note with the app on your phone: the audio lands at the cursor, right under the section you just played, so next week you hear the take and read the chart that produced it. Invite a co-writer or your band to the project and everyone opens the same chart on iOS, Android or the web. Your next step: paste today’s chart into a note and record your first pass under it.

Frequently asked questions

What does a slash mean in a chord symbol?

It names the bass note. C/E is a C chord with E as its lowest note, and D/F# is a D chord with F# in the bass. On guitar, put that note on the lowest string you play; on piano, play it with the left hand. If you can’t, the chord before the slash is a safe stand-in.

What is the difference between C7 and Cmaj7?

Both are a C major chord plus a seventh, but a different one. C7 adds B♭, the lower seventh that sounds bluesy and wants to move on. Cmaj7 adds B, the higher seventh that sounds soft and settled. On a chart, a plain 7 always means the first; only maj7, M7, 7M or Δ means the second.

What does N.C. mean on a chord chart?

No chord. The band stops playing and the voice, a riff or silence carries on until the next chord symbol. It often marks a break before the last chorus, so everyone should stop on the same beat.

What is the difference between sus2 and add9?

Both add the note a step above the root, but sus2 removes the third (C–D–G) and add9 keeps it (C–E–G–D). Csus2 sounds open and undecided; Cadd9 still sounds major. Some charts write C2 for either, so check the recording.

Why does my chord chart have an H?

It’s a German chart. H is the note English calls B, and a German B is B♭. Paste the chart into the chord transposer, choose letters, and it writes H as B and B as B♭.
