This series of graded albums has originated on the basis of a need for a wide range of study material that would comply with all requirements of modern piano teaching. The material is designed also to help master problems in technique and expression.

Book 1 is designed for pupils who have already mastered the elementary level of piano playing. Its studies have been selected according to the principle consistent alteration of specific technical problems.

Book 2 further elaborates the technical problems included in Book 1. At this stage of practising studies it is important to encourage the student to work out properly technique, strokes and dynamics in each piece.

Book 3 is technically more demanding: as well as a new set of technical problems it elaborates the ones introduced in the first two books. This book also includes a number of repertoire pieces in which it is possible to practise the specific technical problems introduced.
