# Layer (experimental)

This feature is still experimental and only visible if MuseScore is started using the '-e' option, see [Command line options](/3/appendix/command-line-options.md)

For the Open-Goldberg project, the ability to create different versions of the score was needed. One version is the "Urtext", a score which is close to the original version of Bach. A second version could be a Czerny variation, which in addition to the Urtext, contains fingerings.

The layer feature allows creating different versions out of one score file. If you want to add fingerings, you have to create a layer and tag the fingering elements with the layer name.

First, create layers:

Second, create a score variant:

Add the visible layer to the score variant, then select all fingerings and tag them with the name of the score variant:

Default layer:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://handbook.musescore.org/3/advanced-topics/layer-experimental.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
