Singing together is another hallmark of the Charlotte Mason Education. As simple a it seems, it's a short spot in your homeschooling day that will come to mean more than you can ever imagine - to you AND your kids.
Don't worry about how it sounds! Years from now, your kids won't remember the sound, but the experience.
Here are my favorite resources for music in a Charlotte Mason homeschool for singing with your kids (Composer study and solfege will be covered in another post - stay tuned!)
Little Songster (a fantastic (and beautfiful!) free website for folk songs)
Children's American Folk Songs (youtube)
Hymns for a Kids' Heart - book and corresponding youtube channel
Best Loved Hymns (youtube channel)
Center for Church Music - a great website where you can search by lyrics, title, or composer and also download sheet music
