How to make a lead sheet: melody, chords, and lyrics

A lead sheet is a compact way to write down a song: the melody, the chords, and the lyrics on a single page, with everything else left to the performers. It is the format jazz and popular musicians reach for when a full score would be overkill. This guide explains what a lead sheet is, how to read chord symbols, and how to build one step by step in Flat.

What is a lead sheet?

A lead sheet specifies the three essential elements of a song: the melody, written as a single line in standard notation; the harmony, shown as chord symbols above the staff; and the lyrics, written as text below the staff. The word "lead" refers to the lead line, the song's primary melody.

What a lead sheet leaves out matters just as much. It does not spell out chord voicings, voice leading, a bass line, or any other part of the accompaniment. Those are added by an arranger or improvised by the players, which is why a small jazz group can read one lead sheet and each invent their own part. Collections of lead sheets are called fake books, and the best known is The Real Book, the standard reference for jazz tunes since the early 1970s.

What you need before you start

Three things: the melody you want to capture, the chords that go under it, and the key and time signature of the song. If you are transcribing an existing tune by ear, find the key first, then the chords, then the melody on top. If you are writing your own, a chord progression is a good place to begin.

How to make a lead sheet in Flat

1. Create a new score and set the basics. Open Flat, pick a single instrument (piano or any treble-clef lead instrument works), and set the key and time signature so the editor knows what belongs in the key and how many beats each measure holds. (Set the key and time signature)
2. Write the melody. Enter the lead line on the staff one measure at a time. You can click notes in with the mouse or type them with keyboard shortcuts, which is faster once you know them. (Note input shortcuts)

3. Add the chord symbols. Place a chord symbol above the staff each time the harmony changes. A symbol stays in effect until the next one appears. (Chord symbols Flat supports)

4. Use slash notation where you want rhythm without melody. Slashes tell the rhythm section to play the current chord in a written rhythm without dictating exact notes. A chart that is only slashes and chord symbols, with no written melody, is a chord chart rather than a lead sheet.

5. Add the lyrics. Type the lyrics under the melody, one syllable per note. Hyphens split a word across notes, and an underscore stretches one syllable over several. (Add lyrics)
6. Label the page. Add the title, composer, tempo, and any style marking at the top. That is the information performers expect to find on a lead sheet.

How to read chord symbols

A chord symbol uses a letter for the root, plus a suffix for the quality. A plain letter is a major triad (C). A small "m" or "min" means minor (Cm). "dim" or a small circle means diminished (Cdim, C°). A plus sign means augmented (C+). A "7" adds a dominant seventh (C7), and "maj7" a major seventh (Cmaj7). The symbols name the chord independently of the key, so "Gm" always means the same notes wherever it appears.

Tips that keep a lead sheet readable

• Aim for about four measures per line so singers and players can scan ahead.
• Write the melody in its plainest rhythm. Performers will add their own phrasing.
• Keep chord symbols large and aligned over the exact beat where the chord changes.
• Make beat three visible in each measure, tying across it if needed, so the pulse is easy to find at a glance.

Share and export your lead sheet

Once the page is done, share a link so bandmates can view or edit it with you, with comments tied to specific measures. When you are ready for the gig, export a print-ready PDF, or a MIDI or MusicXML file to carry the tune into another program.

A lead sheet gives everyone just enough to play from and room to make the song their own. Write your melody, add the chords and lyrics, and you have a chart a whole ensemble can read. Try Flat for free!
