Beginners Learn Piano - Materials for Children - Hans Bodemann
Hans Bodemann's books are mostly for German-speaking learners as they are in German. The series is very well conceived and works very well for the very first steps at the piano such as beginning to learn notes. The books work better in combination with each other - for instance Kleine Finger am Klavier Book 1 & Übung macht den Meister Book 1. Children enjoy the books and progress well with them. There are no pictures but the notes are big and a lot of the tunes / pieces are systematically progressing arrangements well-known music. The books are suitable for the youngest as well as older children as well as adult learners.
