Theory Workbooks 1 and 2 are correlated with the All for Strings method books and are suitable for classroom or individual use. Each page features exercises and games which encompass music fundamentals introduced in the method books. Students start by learning the piano keyboard to increase their understanding of the intervals. They also work with fingering chart exercises so that basic theory can be immediately applied to their instrument. In addition to drawing clefs, notes, key and time signatures, students learn about musical phrases and begin composing. Puzzles and musical math games are also included.
