The Harmony has 17 different alarm sounds to choose from, all of which can be heard in videos uploaded to the Mudita YouTube channel (links listed below).

It isn't possible for users to add more alarm sounds to the Harmony's library.

Here is a list of links to videos with all Mudita Harmony alarm sounds (in the same order as they appear in the clock's alarm settings):

NOTE: These video links are temporarily unavailable. New versions will be uploaded soon and the links will be updated. Apologies for the inconvenience!
