There are a lot of great places to get music and sound effects online. I generated the sound effects we use in this chapter with SFXR (http://www.drpetter.se/project_sfxr.html), which is a tool used to generate old school 8-bit sound effects that sound like something you would hear in an NES game. These kinds of sound effects may not be to your taste. OpenGameArt.org also has a large collection of sound effects (https://opengameart.org/art-search-advanced?keys=&field_art_type_tid%5B%5D=13&sort_by=count&sort_order=DESC) and music (https://opengameart.org/art-search-advanced?keys=&field_art_type_tid%5B%5D=12&sort_by=count&sort_order=DESC) with a variety of open licenses, so make sure that you look over the license of any sounds or art on that website before you use it.
