Writing Lyrics: Custom vs Auto

Lyrics are where a song stops being background music and starts saying something. Suno gives you three ways to handle them: let it invent lyrics from a theme, write your own from scratch, or co-write with an AI assistant like ChatGPT or Claude and paste the result in. This lesson shows you when to use each and how to write lyrics that sing well.

What You'll Learn

• The three approaches to lyrics in Suno and when to use each
• How to format lyrics so Suno sings them the way you intend
• Using structure tags to control verses, choruses, and more
• Writing singable lyrics that scan and rhyme naturally
• Co-writing lyrics with a separate AI assistant

Three Ways to Get Lyrics

Auto lyrics are the fastest. In Custom mode you give Suno a theme and it writes words to fit. Great for demos and when the vibe matters more than the exact message. Your own lyrics give total control and are the right choice for a personal gift, a brand jingle, or anything where the words carry meaning. AI co-writing is the sweet spot for many people: you brief a chatbot, get polished lyrics in seconds, edit them, and paste them into Suno.

Formatting Lyrics with Structure Tags

Here is the single most useful trick in this lesson. Suno reads square-bracket tags in the lyrics field as instructions about song structure. These are often called meta tags. They tell the model where each section starts and how the song should be built.

The common structure tags include:

[Intro]
[Verse]
[Pre-Chorus]
[Chorus]
[Bridge]
[Outro]

A typical pop structure laid out with tags looks like this:

[Verse]
City lights blur past the window pane
Another midnight, another train
I keep your letter folded in my coat
Every word a promise that you wrote

[Chorus]
So I'm coming home, I'm coming home
No more running, no more roads alone
Count the miles and I'll be there by dawn
Hold the light on, I'm coming home

[Verse]
Coffee cups and stations I don't know
Watched a hundred strangers come and go

[Chorus]
So I'm coming home, I'm coming home
No more running, no more roads alone

Because the chorus text repeats, Suno tends to reuse a similar melody for it, which is exactly what makes a chorus feel like a chorus. Structure tags are your main tool for building a song that feels arranged rather than aimless. The next lesson goes deeper on structure and vocals; here the key point is that bracketed section tags belong in the lyrics field.

You Can Add Sound Cues Too

Beyond section tags, you can drop short descriptive cues in brackets to hint at performance or production. Results vary, so treat these as suggestions the model may or may not honor:

[Guitar solo]
[Soft piano intro]
[Beat drops]
[Whispered]

Use these sparingly. One or two well-placed cues can shape a moment; a dozen of them tends to confuse the generation.

Writing Lyrics That Actually Sing

Lyrics on a page are not the same as lyrics that sing well. A few principles make a big difference:

• Keep lines a similar length. Singable verses usually have lines of roughly even syllable count. Wildly uneven lines force the model into awkward phrasing.
• Rhyme, but gently. End rhymes on alternating lines feel natural. You do not need perfect rhymes everywhere; near-rhymes ("coat" and "wrote," "home" and "alone") sound fine.
• Repeat the hook. The chorus is your most memorable line. Repeat it, and keep it simple and concrete.
• Favor concrete images. "The coffee's cold, your chair is bare" lands harder than "I feel a lot of sadness now." Specific pictures move people.
• Mind the length. Very long lyrics may get cut off by the song's length limits. If you have a lot of words, plan to extend the song, which you will learn in Module 3.

Co-Writing Lyrics with an AI Assistant

You do not have to write lyrics alone. A general AI assistant such as ChatGPT, Claude, or Gemini is excellent at drafting lyrics you then refine and paste into Suno. The key is a specific brief. Here is a prompt you can adapt:

Write song lyrics for an upbeat indie pop track about moving to a new city
and feeling both scared and excited.

Structure it with these sections and label each one on its own line in
square brackets: [Verse], [Chorus], [Verse], [Chorus], [Bridge], [Chorus].

Keep lines short and similar in length. Use a simple, repeatable chorus with
a clear hook. Rhyme the even lines. Use concrete, visual images. Avoid cliches.

Because you asked the assistant to label sections with bracket tags, you can paste its output almost directly into Suno's lyrics field. Then edit: cut lines that feel generic, sharpen the images, and make sure the chorus is a line you would actually want to hear twice. The assistant gets you 80 percent of the way; your edits make it yours.

One caution: keep the lyrics field and the style field separate. Section tags and words go in lyrics; the sonic description (genre, mood, instruments) stays in the style field.

A Quick Lyric Workflow

Key Takeaways

• Suno offers auto lyrics from a theme, fully custom lyrics, or AI co-writing; choose based on how much the exact words matter.
• Square-bracket structure tags like [Verse], [Chorus], and [Bridge] go in the lyrics field and control how the song is arranged.
• Repeating the chorus text encourages a repeated, memorable melody.
• Write singable lyrics: even line lengths, gentle rhymes, a repeated hook, and concrete images beat abstract statements.
• Co-write with a chatbot by giving it a specific brief that asks for bracket-tagged sections, then edit before pasting into Suno.
