# Music

> Create songs and instrumentals with Suno and other music models, then extend, cover, mash up, edit, split and convert them with Nodaro's MCP music tools.

Source: https://nodaro.ai/docs/mcp/tools/music

The **music tools** let an assistant make and edit music in Nodaro. `generate_music` creates a track from a prompt, and the `suno_` tools use Suno's full feature set: songs with your own lyrics, covers, extensions, mashups, section replacement, stems, WAV files and music videos. Every tool needs the `workflows:execute` permission and returns a job id.

## `generate_music`

Creates a music track from a prompt. It works like the [Generate Music](https://nodaro.ai/docs/nodes/audio/generate-music) node.

**Permission:** `workflows:execute`. **Credits:** 30 with a Suno model, 180 with MiniMax.

## Frequently asked questions

### What is the difference between generate_music and suno_generate?

generate_music is the simple tool for a track from a prompt, with Suno V6 by default and MiniMax for short instrumental loops. suno_generate exposes Suno's own controls, such as custom mode with your lyrics and style, weirdness, style weight and negative styles.

### How much does a Suno song cost?

30 credits per generation, on every Suno version. Lyrics, style boost, WAV conversion and music videos cost 10 credits, and replacing a section costs 20.

### Can I split any song into stems?

suno_separate_stems works only on a song made with Suno in Nodaro. For any other audio, use separate_audio, which splits vocals and instruments with Demucs.

### How do I make a song with my own lyrics?

Call suno_generate with custom_mode set to true, your lyrics with section tags such as [Verse] and [Chorus], and a style. With generate_music, passing lyrics switches to the same custom mode.
