This book (Part 1), has helped me a lot with my music theory studies when I was a kid (I'm still using it now too). This book is for those who are taking the grade 1-5 of the ABRSM (Associated Board of the Royal Schools of Music, London, UK) theory exams.
Even though it is for lower grades, I still use it to refresh my memory about something that I forgot. Especially in understanding the cadences, articulation etc etc.
I really highly recommend this book (including the Part 2, which is for higher grades) to anyone who is studying music or those who want to know more about Music Theory. May it be a student studying music in a University/Music Conservatory or to teachers out there.
A must have for those who are serious into music and how music really function.
