A Listening Guide from Kolbe Academy. It gives a 12 year music appreciation framework, with suggested composers and recordings for each year. It is short, but I find it useful. I especially like that it suggests specific recordings of the pieces, because I don't know enough about music to choose among 15 different recordings of Handel's Water Music, for example. Kolbe is a Catholic school, and some of the music choices reflect that.
Comments briefly explain the significance of many pieces and composers.
In the second half also has record label information for all the works in both sections of the Guide. The entries are listed chronologically by composer, facilitating a developmental approach to the study of music history. The guide also includes an index, making favorite composers easy to locate.
