On the way to Emma, Jasper listens to some street musicians. Emma is busy playing the violin when he arrives. Jasper would also like to make music for other people, but he has no instrument. Then Emma gets him the old tuba from her grandfather's attic. The two try to play a duet, but the old thing is very clogged. A load of soapy water does not necessarily improve the sound, but the bubbles that now float across the street are definitely drawing a lot of attention to the street musicians.
