## A.3 Smyčcový kvartet

### A.3.1 Jednoduchá smyčcový kvartet

This template demonstrates a simple string quartet. It also uses a `\global` section for time and key signatures

>       \time 4/4
>       \key c \major
>     }

### A.3.2 Hlasy smyčcového kvartetu

The „String quartet template“ snippet produces a nice string quartet, but what if you needed to print parts? This new template demonstrates how to use the `\tag` feature to easily split a piece into individual parts.

You need to split this template into separate files; the filenames are contained in comments at the beginning of each file. `piece.ly` contains all the music definitions. The other files – `score.ly`, `vn1.ly`, `vn2.ly`, `vla.ly`, and `vlc.ly` – produce the appropriate part.

Do not forget to remove specified comments when using separate files!
