The city branding case of HafenCity Hamburg – “Hello, HCH!” uses music to link people and the city; people can feel HafenCity with music. They can also create music from HafenCity. The brand communication consists of three parts; the first part is the new HafenCity visual identity (e.g. dynamic logo). The second part is the app; users can use this app to create and listen to music from HafenCity and explore the HafenCity with its music. The last part is the Music Festival.
