Hi Allison (and Lourdes),
I'm thinking you musical folks can create a nice list for those musically inclined families out there! Meanwhile, I'll chat, even though I know very little about studying music. We did do all the MFW music, which my son liked a lot. I think it was because he was schooling alone, and it got very quiet here. We did lots of music in between our studies.
As you mentioned, starting in EX1850 you will review all the classical composers during the times that they lived. The classical musicians studied during earlier years were introduced pretty much in chronological order. We did more with them during the reviews in EX1850, for example (again, way down at the end of my long post): http://board.mfwbooks.com/viewtopic.php ... 806#p41806
And then in 1850MOD, you will find more of what you describe -- Foster & Sousa (Oh Susanna and such), Jazz, and even patriotic-type songs. You could plan to delve into all of those even further -- and share with the rest of us!
As for earlier years, in ECC there were the folk songs on the Wee Sing CD. Did you do those? Do you have more ideas to add? One similar CD we had got after listening to the one from the library was called World Music -- I see I described it here http://board.mfwbooks.com/viewtopic.php ... sic#p60239
We listened to another CD with Spanish Guitar, mentioned way down near the end of this post: http://board.mfwbooks.com/viewtopic.php ... 909#p58909
In CTG, it might be hard to find ancient music (or to ensure we know what we're listening to!), although maybe you studied that? There are a couple of book basket CD suggestions that "relate" to ancient topics (rather than being ancient music), like an opera on the 10 plagues and something on creation. We did listen to a little Jewish music at our house, which seems historical: http://board.mfwbooks.com/viewtopic.php ... 263#p35263
In RTR, there are some actual period CDs mentioned in regard to medieval chant, but if you have more ideas that would be great! There are also more that "relate" to the period, such as William Tell, the planets, and Russia/Peter & the Wolf.
Well just throwing out some things we did for fun!
