Here Comes Frankie
This book is currently out of print.
Frankie decides that the extremely quiet life he leads with his parents needs livening up and he acquires a trumpet. As he learns to play, he discovers that he can see and smell sounds conjured by the music as well as hear them and this awakening of the senses extends to his parents and neighbours too. This is demonstrated visually through colours and patterns in the illustrations and the book begins and ends with palette pages on which each colour is evocatively named. A brief note explains that what happens to Frankie is known as synaesthesia and mentions creative people who have also experienced this.
