The Adventurer Book (Level 2A) gives the student full exposure to playing the wide range of notes of the entire grand staff, as well as first exposure to treble, bass and inner ledger notes. A further explanation of syncopation is given in the form of counting and clapping exercises and fun, lively, syncopated pieces. Harmonic sixths are introduced, expanding the left hand. An introduction to root-position triads and broken chords is also presented.
