Abstract:
The purpose of this study was to assess the memory of different musical
pitch levels of the human brain. The randomly selected vocal music students were asked
to sing two lines of their preferred song. The department of music of the University of
Jaffna of the Sri Lankan Government was used as the setting for this study. The class
rooms and the surroundings were kept silence and also kept without any interruption
from any pitch generating musical instrument. The students who were on their final
year Bachelor of Fine Arts (Vocal music), were recruited for the study. Their vocals
were recorded with a digital recorder and measured with an automatic chromatic tuner
to find out the pitch level of the each student, while they sung in the each 5 class rooms.
There were 40 recordings taken for analysis. Music therapy is an effective nursing
intervention in decreasing anxiety, depression. But, the research in therapeutic music is
still going on worldwide, to find out how music therapy works. According to the
findings of this research, the musical pitch and the therapeutic music had no
relationship, because the different musical pitch levels were not memorable or not
identical by the human brain. In Sri Lanka, the implementation of music therapy in the
government hospitals will relieve the depressed public by the war, without any side
effects and also without high expenses and without the importation of drugs. It will help
for the post-war economic development of the nation.
