# Introduction

&lilypond; (lilypond.org) is an open-source music engraving program, producing very high-quality sheet music printouts from fairly simple text input files. Those text files can be created with any text editor, and &lilypond; then loads the text file and outputs a beautiful engraving, by default in PDF format.

&frescobaldi; is an application designed to make editing &lilypond; music scores faster and easier. You still will need to learn the &lilypond; input language. If you read the "First Steps" section of this User Guide, you'll also pickup some &lilypond; basics. Then you can continue to learn using the Learning Manual from LilyPond's excellent online documentation.

Virtually all keyboard shortcuts that are mentioned in this User Guide are the default ones; you can change them using Settings Configure shortcuts....
