Turn up the volume, dial up the drama

From loud to soft, even louder and even softer, dynamics are crucial to the dramatic effect of music. Tom Service discovers just how loud and soft classical music can be, and pop music that is louder still. Is it all about loudness or are the quiet moments more evocative? With the Royal College of Music’s Head of Composition, William Mival and BBC Sound engineer Matilda Macari gives an insight into just how loud the music that we're hearing through our radios is. Produced by Calantha Bonnissent.
