Grade 4–6—Beginning with a discussion of different music styles, these books go on to define the relevant genre, discuss its history, and describe the elements particular to it. Chapters cover instruments often used in the musical style, such as cellos in Classical; a wide range of musical legends and other great performers of noted songs or works; music production; and collection, including information on downloading, and copyright agreements and violations. The titles direct young musicians to online resources including performance sites specific to each type. A wide range of works from and performers of each style are referenced (the sidebar of opera plots in Classical details decidedly adult themes, such as adultery in Carmen).
