The document summarizes and compares two music education series - Lowell Mason's 19th century "The Song Garden" series and Audrey Snyder's modern "The Sight-Singer" series. Both series use a movable-do solfege system and focus on rhythmic development before pitch. "The Song Garden" contains translations of German songs and information on singing techniques at the start of books. "The Sight-Singer" has original songs and places theory on each page. While the modern series has improvements in presentation, the sequential approach and concepts are similar.
