免费 AI 音乐生成器: 从文字创建歌曲

AI music generation has matured from a novelty into a practical creative tool. Free.ai's music generator lets you describe the music you want in plain English and receive an original composition in seconds. No musical training, no instruments, no expensive software — just type and listen.

The process is simple: enter a text prompt describing the music you want. This can be as specific or general as you like. "Upbeat electronic dance music with a strong bass line at 128 BPM" will produce something very different from "gentle acoustic guitar with soft piano, suitable for a meditation video." You can specify genre, mood, instruments, tempo, and duration to guide the AI.

The AI understands musical concepts and genres including pop, rock, electronic, jazz, classical, ambient, hip-hop, lo-fi, cinematic, and many more. It can blend genres ("jazz-infused lo-fi hip-hop"), match specific moods ("triumphant and uplifting" or "dark and suspenseful"), and target specific use cases ("background music for a cooking tutorial" or "intro music for a tech podcast").

Common applications include background music for YouTube videos, podcast intros and outros, social media content, presentations, video games, short films, advertisements, and personal creative projects. Content creators especially benefit because AI-generated music is royalty-free — you own the output and can use it commercially without licensing fees or copyright claims.

For best results, be descriptive in your prompts. Instead of "happy music," try "cheerful ukulele and handclaps with a whistling melody, like a summer commercial." Reference specific styles without naming copyrighted songs. Experiment with multiple generations to find the perfect track, then download it as MP3 or WAV. You can also generate multiple variations and combine sections using any audio editor for a custom arrangement.
