A Cross-Cultural Music Analysis System with Culture-Dependent Semantic Metadata Extraction Mechanisms
Working with my professor, my assistant professor, we wrote a paper about
this topic named “A
Cross-cultural Music Museum System with Impression-based Analyzing
Functions”. The paper was accepted and will be presented in IADIS
International Conference, e-society conference, Avila, Spain, March 10-13, 2011.
Research's SummaryThis research proposes a cross-cultural music
analysis system (CCMA), which is a new computational environment to promote
cross-cultural understanding and communication through the use of multimedia.
This system provides a new platform for evoking the imagination of users
regarding cultural diversity by presenting the variety of emotional responses to
music that different cultures express. The system consists of music analysis,
search and visualization functions, and is characterized by three main features
as follows: (1) a culture-dependent semantic metadata-extraction method, which
extracts musical elements (e.g., key, pitch and tempo) and generates impression
metadata (e.g., sad, happy and dreamy) corresponding to properties of each
musical culture, (2) a cross-cultural computing mechanism to represent the
differences and similarities of various musical cultures, and (3) easy-to-use
interfaces which help users join the system’s database creation process. In our
implemented prototype system, traditional music is used as the common cultural
determinant among different cultures. The significant contribution of our system
is its multimedia database technology, which applies Kansei, a Japanese term
that means psychological-feeling to compute and increase awareness of cultural
By using the system’s functions, a user can acquire insights about other cultures by comparing their own impression of a musical piece to how a different culture interprets the same musical piece. Furthermore, users can understand the differences and similarities in musical expression of a particular impression (e.g., sad, happy and dreamy) as well as in interpretation of a music piece among various musical cultures.
To extract impression metadata from non-Western classical music, this study builds a model, called the “Musical Elements–Impressions E-I Operator” to represent the complicated relationship between musical elements and impressions from composers’ viewpoint. The significant features of our extraction method are (1) to normalize musical elements according to standard parameters of a musical-culture, and (2) to use typical music samples and create "cultural music filters" which apply culture-based weighting to musical elements before converting those elements to impressions.
This paper also presents the experimental results and insights derived from
those results, which have been observed through the operation of our music
analysis prototype system. The experimental results make it possible to realize
how groups of musical-elements show up as having the same impression-meaning
across different cultures.
