Imaginative accounts of the origins of music illustrated with examples of the relationships between music and maths and between music composers and performers. The book suggests how scales and octaves originated, shows why some notes jar when played simultaneously while others harmonise, explains key and time signatures, and answers questions such as how lengths of piano strings are calculated.
The use of teacher–student format presented by a fictional music composer to students both young and old accentuates the ease of understanding and readability of the book.
