This book was written for guitar students who want to develop their sight reading skills. This material focuses on single line exercises in first position (first four frets), including the use of open strings. However, the student can read most of the exercises all the way up to the fifth position (frets 5 to 8). The content is divided into five units. The first unit focuses on the top three strings and simple rhythms. The second unit introduces the bass notes, and includes the use of eight notes. The third unit contains eighteen duos, with the use of key signatures and rhythmic materials presented in the first two units. The fourth unit is subdivided in X rhythmic groups, each of them presenting different rhythmic patterns.

The first example of each group presents the rhythms in a single line exercise that can be sung or played using one single note on the guitar. The goal of those exercises is to focus solely on the rhythm. These rhythmic exercises are followed by three duos that are based on the rhythms studied up to that point.
