When her father dies, music historian and trombonist Dr Emily MacGregor finds that music has become too much. Listening, let alone playing, music is suddenly too difficult. This is problematic given that she's a broadcaster, writer and academic working with classical music.

It leads her on a journey of discovery: from the arrangement of an Isaac Albéniz piece she finds on her father's guitar stand, through encounters with psychologists, orchestras, summer schools and funeral celebrants, to the lives and works of individual composers who wrote music so often in the midst of loss. What is it about our experience of music that cuts so sharply to the heart of our emotions? And why is it more than any other artform painfully, exquisitely crucial in the evoking of memories?

An erudite, lyrical, gently humorous and healing journey to rediscover the purpose of making and participating in music.
