As a piano teacher or any student new to piano, there is a lot of choice with types of books to use. And it can be easy to feel overwhelmed with choice. Different books each serve their own purpose in developing a well-rounded musical journey. Repertoire across musical genres, technique, theory, enjoyable sight-reading should all be covered. And hence there is a need for multiple books to be used to grow each of these skill areas.
The thrill of getting a new book can be motivating for some students, especially as they recognise their own progress with the instrument. This is particularly true for younger students using method book series which are aimed at taking a complete beginner to a Grade 1 level.
One of the responsibilities of a piano teacher is guiding students on learning appropriate repertoire, to develop musicality and technique. Perhaps learning a particular exercise and incorporating that into practise at home will help the student better interpret and play their current repertoire. Perhaps they are lacking understanding of music theory and need this foundation strengthening.
Below are just some of the book series I find myself referring back to, and have seen success with. All I have either tested in action in my studio, or have personally used myself as a young piano student.
