Large numbers of notifications devalue individual ones, making user tracking of important smartphone notifications such as text messages and emails harder. Users are essentially being spammed by notifications, especially on android with undismissable notifications.
What is the goal of notifications? That's a question that our team came up with a few answers for. Notifications should contain maximal relevant information in an ultimately sparse experience. The loading of the notification tone to integrate music theory as a information channel is an intuitive step forward in smartphone UX. Major vs minor key, dissonant vs harmonic, lower pitch vs higher pitch, these are just some of many possibilities.
