Panowsky, Charlotte, Illustrations for children aged 4 and up. The second volume features colored illustrations and clear finger images, aimed at further developing the technique of the left and right hand, and primarily introduces playing in different keys. In addition to well-known children's and folk songs, it also includes two-part classical pieces that help enhance students' reading skills and prepare them for ensemble playing. The second finger is incorporated, and dotted notes, sixteenth notes, first double stops, as well as close and wide fingerings and changing hand positions are introduced and practiced. Depending on the child's developmental stage, the third volume of the cello school, which is divided by finger positions and keys and thus offers easily accessible sections with additional practice material, can be used in parallel with the second book.
