Find copyright-free music for an animation soundtrack

What can we use if we can't access the suggested copyright-free sites or an adult to download tracks?

If you can't reach the listed sites or an adult to download, ask the adult to use another reputable copyright-free library (for example FreePD or Jamendo) and follow the instruction 'Ask an adult to download each track you picked' and 'save each downloaded track into a new folder for your animation project'.

What should we do if the site's filters don't return tracks with the exact mood, tempo, or length we wrote down?

If the search filters don't find an exact match, pick a close track from the previews, then with an adult use a simple audio editor to trim, loop, or adjust the track so it matches your animation's exact length and pacing before you 'Play each track while watching a short clip of your animation'.

How can this activity be changed for different age groups?

For younger children simplify choices to mood and length and have an adult open one listed site and download two tracks, while older kids should perform the full steps including checking license text, writing license info in their notebook, and editing tracks to fit timing as described in the instructions.

How can we extend or personalize the soundtrack beyond choosing a single track?

You can enhance the soundtrack by mixing two tracks or adding recorded vocals and sound effects in an audio editor (with an adult), then note each source's title, artist, website and license in your animation credits as required before sharing on DIY.org.
