From my own homeschooling experience (several yerars, including a home daycare-preeschool run along homeschooling lines, and active in parent groups), I can tell you that pedantry is out. It has to start from the children's interest and from them catching music from the air, and then wanting organized help when they ask for it. Other than that, using music to teach other material is a good way to go.
As a child who was treated in that fashion, I can tell you that the most useful thing I recall was curling up close with my dad to hear his records, and his tastes were varied. Over several years he taught me, one instrument at a time, how to listen to each part separately as well as hearing the sections and the whole. The more music I do, the more I realize how unique that gift was, and how valuable it was. I absorb it all when I listen, and can manipulate what was recorded in my mind to play with all kinds of ideas, and I think it's why I learn tunes so fast.
Fill the air with music, played live and recorded, and they will be drawn to it if that's where they need to go. Baroque music in partuicular will give them a strong foundation in rhythm and math.
