When choosing music for use with educational software, consider a royalty-free recording that could save you several hundreds of dollars in licensing. However, if you would like to make the music part of the trademark of your software, it might be necessary for you to hire a talented musician to make an original composition.
It is also possible to use the more popular children's songs for background music for use in your educational software. However, you need to apply for a license to use these songs and record them along with your program. While this is the more preferred option to get the best possible response from children, the complicated licensing laws and procedures could be hard to understand. The children may be able to easily identify with your song. But it might not be worth all the tasks in front of you. Unless you own a big ticket software company, going for this option is unfeasible.
Hiring a composer might be the next better choice. The only issue with this is you might need to apply for copyright protection to make sure that nobody would pirate the original song that you have paid for to create. And like the licensing issue, this could be a long, tedious, and complicated job to do.
Royalty-free music obtained in a digital format is the best way to go, as it would allow you to easily integrate your choice of a song in your educational software. The more lively and energetic the songs you choose, the better effect it will have on children.
