Study book recommended by the piano teacher, I find that it gradually increases in difficulty. I appreciate it.

Method requested by my daughter's piano teacher.

very well perfectly suited

A very fun and comprehensive method, everything is indicated, it's pleasant for both the teacher and the student. The student plays with both hands right away. He also learns the bass clef because the names of the notes are indicated, pure happiness. Thanks to the author. I also use it for adults.
