Having taken piano lessons for 15 years and being the daughter of a piano teacher of 30+ years, I was a little surprised by the terms that this book used for basic music terms. A crotchet = quarter note, a breve = whole note, a semi-breve = half note, etc. Terms I have NEVER heard before in the 20 years of exposure to music. My mother hadn't either. I spent a lot of time crossing out words and replacing them with the correct terms so not to confuse my students. The activities are good, but the explanations are not as thorough as I would like. The terminology is the worst part about this book.
