Strategies of Using Multimedia Technology to Optimize Music Classroom Teaching in Primary and Secondary Schools

Abstract

Information technology has entered every aspect of life. The music classroom is no exception for training music talents. The development of information technology has become an inevitable trend of social development. Not only the call of the era of computer multimedia teaching but also the music curriculum standard under the background of quality education has put forward high requirements for today’s computers. From this, we can realize that it is crucial to transform teaching concepts, actively practice and explore, and seek new teaching models. As the main auxiliary teaching method, multimedia technology is known and used by most primary and secondary schools, and is widely used in music classroom teaching. This paper deeply analyzes the role and position of multimedia in music teaching in junior high school music classroom teaching, compares multimedia technology with other educational technology means, and explains the advantages and limitations of the implementation of music classroom teaching assisted by multimedia educational technology means. At the same time, this paper turns the cognitive problem of selective attention into the problem of measuring the auditory attractiveness of objectively existing music parts. The specific process is as follows: first, on the CQT spectrum of real music audio, this paper uses the auditory cognitive model based on auditory saliency, and uses the Bayesian inference mechanism of time series to propose the calculation method of quantitative features of auditory saliency. Then, TANN network is used to identify multiple auditory significant subbands as candidate semitones, and a priori knowledge obtained from the generalized chord structure is introduced to standardize the chord like structure at each time in the candidate melody stream, which improves the accuracy of the melody stream’s description of the original music. Finally, according to the data analysis of teaching practice, the teaching objectives of “order” and “circulation” in social and natural life have been well realized through “rhythm” insight in this teaching practice unit.
