The second theory book by Lina Ng is the second workbook in a series of three, designed to provide a smooth transition to Grade 1 Theory. It contains numerous exercises and games that encourage a broader understanding of music, even in the very early stages of learning.

This second book includes exercises for finding notes on a piano keyboard, new notes on the staff, new notes in bass, rests, octaves, the rest of the octave, ties, tests, and games.

My First Theory Book and My Third Theory Book are also available, along with a series of five books from the Theory Made Easy series.
