You type a few lines of lyrics. You hit a button. Thirty seconds later, a complete song plays back — vocals, melody, instrumentation, the works.

That's what we're building in this tutorial: a minimal but fully functional text-to-song web app powered by the Suno API. Users paste in their own lyrics, pick a style, and get back a real AI-generated song with vocals.

What we're building:

A Next.js app with a simple two-field form: lyrics input + style tags

A backend API route that submits to Suno and polls for results

A frontend that streams status updates and plays the finished song inline

Time to complete: ~30 minutes

Stack: Next.js 14 (App Router), Node.js, Suno API via TTAPI

Prerequisites: Node.js 18+, a free TTAPI account

Why the Suno API for Lyrics-to-Song?

Most AI music tools treat lyrics as optional. Suno's custom mode does the opposite — you supply the exact lyrics, and the model builds the vocal melody, arrangement, and instrumentation around them.…
