'All-In-One: Grades 4-5' is a concise, yet fully comprehensive, step-by-step explanation of music theory from grade 4 to grade 5 for both Associated Board (ABRSM) and Trinity College London students. This book coincides with the publication of the THIRD edition of 'All-In-One to grade 5' (beginner to grade 5) on which it is based, containing much of the same material as the higher grades with a few extra exercises in areas where students need most practice.
