Suno AI: Prompting for a True Single Instrument Solo

Suno is designed to generate complete musical arrangements, which makes it surprisingly difficult to get a genuine one-instrument performance.

Simply prompting for:

“Solo piano”

does not always produce a true solo. Suno may still add drums, bass, percussion, synths, or other instruments associated with the genre.

I experimented with a prompting-only approach in Suno V6, without using Suno Studio, voice input, or voice-to-instrument techniques.

The basic idea

The prompt needs to do more than identify the instrument.

I use Suno's Advanced mode with:

Lyrics:
[Instrumental]

Styles:
A combination of instructions such as:

• solo [instrument]
• intimate studio recording
• close microphone
• dry signal
• single track
• strictly no accompaniment
• no drums

Then I add genre-specific exclusions.

This is important because Suno tends to associate a genre with its normal instrumentation. A house track may introduce drums and synths; salsa may introduce percussion; funk may introduce bass and drums.

The trick is therefore:

Specify the one instrument you want + explicitly exclude the instruments you don't want.

Testing the approach

I tested the method across several very different styles, including house piano, 1980s funk slap guitar, gospel/church organ, 1980s romantic electric piano, French romantic accordion, and a 1950s male a cappella group.

The approach worked across all of these tests, although results can still vary between generations.

I also compared Suno V6 and V6-Wild as part of the experiment.

Using AI to build the prompts

Creating genre-specific exclusions manually can become tedious, so I also used AI to expand the basic template into a more complete prompt for each instrument and genre.

The goal is to make the process reusable rather than manually constructing every prompt from scratch.

I go through the actual prompting process and examples in the video:

The main takeaway is simple:

Don't just tell Suno what instrument to use. Tell it what the performance must contain — and what the genre is NOT allowed to add.
