Lead Sheet Symbols Reference — Intermediate

Pin this next to your keyboard. Everything you need to read and play from a lead sheet. A lead sheet shows the melody on one staff with chord symbols above — you create the accompaniment.

What Is a Lead Sheet?

A lead sheet is a single-staff chart showing:

Melody — written in standard notation on the treble clef
Chord symbols — written above the staff, telling you what harmony to play
Lyrics — written below the staff (if it is a song)

You provide: the left-hand accompaniment, voicing choices, and rhythmic style.

Complete Chord Symbol Guide

Major Chords

Symbol	Meaning	Notes (from C)
C	C major triad	C - E - G
Cmaj	C major triad (alternative)	C - E - G
CM	C major triad (alternative)	C - E - G

If you see just a letter (C, G, F), it is always a major triad.

Minor Chords

Symbol	Meaning	Notes (from C)
Cm	C minor triad	C - Eb - G
Cmin	C minor triad (alternative)	C - Eb - G
C-	C minor triad (alternative)	C - Eb - G

Seventh Chords

Symbol	Type	Notes (from C)	Sound
Cmaj7 or CM7	Major 7th	C - E - G - B	Warm, dreamy
C7	Dominant 7th	C - E - G - Bb	Bluesy, wants to resolve
Cm7 or Cmin7 or C-7	Minor 7th	C - Eb - G - Bb	Smooth, mellow
Cdim7 or Co7	Diminished 7th	C - Eb - Gb - Bbb(=A)	Very tense, dramatic
Cm7b5 or Cø7	Half-diminished 7th	C - Eb - Gb - Bb	Tense but less than full dim

Suspended Chords

Symbol	Meaning	Notes (from C)	Sound
Csus4 or Csus	Suspended 4th	C - F - G	Open, unresolved — wants to go to C major
Csus2	Suspended 2nd	C - D - G	Open, modern, ambiguous

“Suspended” means the 3rd is replaced — the chord is neither major nor minor.

Added Note Chords

Symbol	Meaning	Notes (from C)
Cadd9	Major triad + added 9th	C - E - G - D (D one octave up)
Cadd2	Major triad + added 2nd	C - D - E - G
C6	Major triad + added 6th	C - E - G - A
Cm6	Minor triad + added 6th	C - Eb - G - A

Augmented and Diminished

Symbol	Meaning	Notes (from C)
Caug or C+	Augmented triad	C - E - G#
Cdim or Co	Diminished triad	C - Eb - Gb

Slash Chords (Chord/Bass Note)

Symbol	Meaning	What to Play
C/E	C major with E in the bass	LH plays E, RH plays C major (= 1st inversion)
C/G	C major with G in the bass	LH plays G, RH plays C major (= 2nd inversion)
F/C	F major with C in the bass	LH plays C, RH plays F major
G/B	G major with B in the bass	LH plays B, RH plays G major

The note after the slash is ALWAYS the bass note (lowest note, played by LH). The letter before the slash is the chord.

Reading a Lead Sheet Layout

   Am         F          C          G
|  melody notes on the staff here  |
|  lyrics below the staff here     |

Key rules:

Chord symbols apply from where they appear until the next chord symbol
If a chord lasts a full bar, it appears at the start of the bar
If two chords share a bar, each appears above its beat
Repeat signs (||: :||) mean play the section again

Slash Notation for Rhythm

When a lead sheet shows rhythm without specific pitches:

  Dm7        G7         Cmaj7
  / / / /  | / / / /  | / / / /  |

Each slash = one beat. Play the indicated chord with your chosen rhythm pattern.

Rhythmic hits are shown with specific note values above:

  Dm7            G7
  /  / ♩.  ♪  | 𝅗𝅥    / /  |

This means: play the chord on beats 1, 2, then a dotted quarter + eighth pattern, then half note on beat 1 and regular strums on beats 3-4.

Nashville Number System

The Nashville system replaces chord letters with numbers, making charts instantly transposable.

Number-to-Chord Mapping

Number	Scale Degree	Default Quality	Example in C	Example in G
1	I	Major	C	G
2	ii	Minor	Dm	Am
3	iii	Minor	Em	Bm
4	IV	Major	F	C
5	V	Major	G	D
6	vi	Minor	Am	Em
7	viio	Diminished	Bdim	F#dim

Nashville Conventions

Symbol	Meaning	Example
1	Major chord on degree 1	C in key of C
-2 or 2m	Minor (explicit)	Dm in key of C
5/7	V chord with the 7th in bass	G/F# in key of C
4 5	Two chords in one bar (split evenly)	F G in key of C
1 1 4 5	Four bars, one chord each	C C F G
^7	Major 7th	Cmaj7 in key of C
7 (after number)	Dominant 7th	G7 = “57”

Why Nashville Numbers?

A musician says “Play a 1-5-6-4.” You can play it in ANY key:

Key of C: C - G - Am - F
Key of G: G - D - Em - C
Key of D: D - A - Bm - G

One chart works for every key — just know the key and the numbers.

Creating LH Accompaniment from Chord Symbols

When you see a chord symbol, you have several options for your left hand:

Pattern 1: Block Chords

Play the full chord on beat 1 of each bar (or on each chord change).

Chord: Am F

LH: A-C-E F-A-C

(beat 1) (beat 1)

Best for: Ballads, hymns, slow songs.

Pattern 2: Bass-Chord (Boom-Chuck)

Play the root note alone on beat 1, then the chord on beats 2-3 (or 2 and 4).

Chord: C G

LH: C C-E-G G G-B-D

bass chord bass chord

(1) (2-3) (1) (2-3)

Best for: Waltzes (3/4), country, folk.

Pattern 3: Broken Chord (Arpeggiated)

Play chord notes one at a time in a pattern.

Chord: Am

LH: A C E C (repeat)

1 2 3 4

Best for: Ballads, classical-influenced, flowing songs.

Pattern 4: Alberti Bass

A specific broken chord pattern: bottom-top-middle-top.

Chord: C

LH: C G E G (repeat)

1 2 3 4

Best for: Classical style, Mozart-era accompaniment.

Pattern 5: Rhythmic Comping

Play chords with a rhythmic pattern — syncopation, off-beats, or specific grooves.

Chord: Dm7

LH: Dm7 . Dm7 . . Dm7 Dm7 .

1 & 2 & 3 & 4 &

Best for: Jazz, pop, funk, contemporary.
