Vox Video Lab’s Earworm series presents an illustrated guide to ‘That famous cello song’, with the help of guide, soloist Alisa Weilerstein. What makes this composition so memorable, timeless and beautiful? the presenter asks. 

‘For me, one of the most profound things about this piece is the pedal point,’ says Weilerstein. ‘This means that the bass note remains constant, even though the harmony is changing.’
