All of my teaching is influenced by the Kodály Approach.
My singing students all work through Go for Bronze, the brilliant musicianship course published by the National Youth Choir of Scotland.
My piano students use my own method books DoReMi Piano.
DoReMi Piano Books covers technique for the young beginner; pulse, rhythm and pitch understanding; simple pentatonic songs learn first as games and then on a simplified stave. By the end of Book 1 the student will also have an understanding of time signatures, bars, dynamics and slurs.
Why not check it out. If you are a teacher you will be interested in my thorough Teacher Guide available to accompany DoReMi Piano Book 1.
