Theory Made Easy For Little Children Level 2 by Lina Ng provides revision of material learnt in Level 1 as well as notes in the treble clef (A,B,C), rests, notes in the bass clef (F, E, D, C), position of stems, treble clef, bass clef, games, tests and some manuscript paper to practice music writing. There is also a lesson record and a certificate for signing by a teacher or parent when the book is completed. Specifically suited for children aged 4 to 7, this is the second of two books that present music theory using colourful illustrations and stickers for the exercises.
