How to Use Suno AI Custom Instrumental Mode Step by Step

Mastering Suno AI: How to Create Professional Instrumental Tracks Using the “Custom” and “Instrumental” Modes

If you have ever wanted to produce your own radio-ready music without knowing how to play an instrument or read sheet music, Suno AI has likely crossed your radar. Among its powerhouse features, combining the Custom Mode with the Instrumental toggle is the ultimate secret weapon for creators, video editors, podcasters, and aspiring musicians.

Whether you are looking to build a high-energy workout beat, a haunting cinematic background score, or a chill lo-fi study track, this guide will walk you through everything you need to know to master Suno’s instrumental workflow.

What are “Custom” and “Instrumental” Modes?

By default, Suno operates on a simple prompt system where you type in a genre or idea, and the AI generates a complete song—lyrics, vocals, and all—in one go. However, this leaves you at the mercy of the AI’s random lyric generation.

Switching things up gives you granular control:

• Custom Mode: This unlocks the engine’s backend controls. Instead of just typing a sentence, it opens up dedicated fields for Lyrics (or structural prompts) and Style of Music (genres, instrumentation, and mood).
• Instrumental Mode: Found right inside Custom Mode as a simple checkbox, this tells the AI to strip out all human vocals completely, focusing 100% of its computational power on the musical arrangement, melodies, harmonies, and rhythm.

Step-by-Step: How to Generate Your First Custom Instrumental

Creating a dedicated instrumental track takes less than a minute once you know the workflow. Follow these steps to get started:

1. Open Suno AI: Navigate to the create tab on the platform.
2. Enable “Custom”: Toggle the Custom switch on the creation panel. You will see a text box for Lyrics and a text box for Style of Music appear.
3. Check “Instrumental”: Click the Instrumental toggle. Notice how the lyric box either greys out or shifts to allow structural tags—depending on the version you are using, checking this box automatically tells the system to bypass vocal generation.
4. Define Your Style of Music: This is the most crucial step. In the Style of Music box (which typically has a 120-character limit), describe the exact genre, instruments, tempo, and mood you want.
5. Hit “Create”: Click the button and watch the AI render two variations of your custom instrumental track.

Pro-Tips for Writing Killer “Style of Music” Prompts

Because there are no vocals to carry the narrative or emotion of the track, your Style of Music prompt has to do heavy lifting. Vague prompts like "happy music" will yield generic results. Instead, use specific industry terms, instrumentation, and mood descriptors.

Example Prompt Formulas:

• For Cinematic / Orchestral: Epic cinematic orchestral, booming taiko drums, soaring brass, emotional violin swells, Hans Zimmer style, 120 bpm
• For Lo-Fi / Chill: Chill lofi hip hop beat, dusty vinyl crackle, mellow rhodes piano, soft jazzy guitar chords, relaxing, 85 bpm
• For Synthwave / Electronic: Dark synthwave, retro 80s bassline, driving electronic drums, analog synthesizer leads, cyberpunk atmosphere, 128 bpm
• For Acoustic / Folk: Warm acoustic fingerstyle guitar, gentle upright bass, subtle ambient pad, peaceful, organic, campfire morning vibe
