Using familiar songs, such as Christmas carols, were used to test whether SD patients were able to recognize the tones and melodies of the songs if the patients were just given the words of the song. In the analysis of semantic memory using melodies as stimuli, the contents of semantic memory can include many other aspects aside from recognition of the melody, such as the general information about the music (composer, genre, year of release).

Further exploring the tests of music and semantic memory, results of a study that centered on the comprehension of emotion in music indicated that Alzheimer’s Disease (AD) patients retained the ability to discern emotions from a song while non-AD degenerative disease patients, such as those with semantic dementia (SD), show impaired comprehension of these emotions. Spoken and written language are composed of receptive (i.e., listening and reading) and expressive (i.e., speaking and writing) components.
