With the third issue "First Steps", we advance one more step upward. The fundamental elements of the theory are completed and the pieces bring the child in contact with the main technical problems of piano playing that a beginner pianist may face. In this issue, we preferred to focus on Greek and foreign traditional melodies and on works by great composers that we have arranged to be suitable for the student's level, believing that their contact with the masters of this art will certainly be beneficial. We also continued the series of exercises that started from the second issue, aiming to strengthen the muscles, joints, etc., of the aspiring pianist. We will truly be happy if we manage to make the child feel that music is not just a simple "lesson" but an aesthetic enjoyment that will be achieved through the knowledge provided by the book.
