Abstract
In order to improve the effect of popular music teaching, this paper combines the intelligent music frame feature recognition technology and the semifinished product teaching strategy to construct a multimedia popular music teaching system. Moreover, this paper reexpresses energy detection and zero-crossing detection mathematically from the perspective of aggregation and proposes a new two-level detection method for music frames. In addition, this paper uses the fusion and expansion of the zero-crossing rate detection result to judge whether a piece of speech is a valid musical speech. Finally, this paper uses a four-tier architecture to design the system framework, constructs the system functional modules, builds a multimedia pop music teaching system that incorporates semifinished teaching strategies, and then validates the performance of the system. From the experimental research, it can be seen that the multimedia pop music teaching system integrated with the semifinished product teaching strategy proposed in this paper can play an important role in music teaching and effectively improve the effect of music teaching.
Highlights
As a kind of music culture with great characteristics of the times, popular music is more and more widely used in music teaching, and it has won the attention of all walks of life
From the application point of view, this paper studies a music frame recognition system based on mobile terminals
T 1 e estimation of GMM parameter values is based on the maximum likelihood criterion (ML), which is realized by the EM iterative algorithm
Summary
As a kind of music culture with great characteristics of the times, popular music is more and more widely used in music teaching, and it has won the attention of all walks of life. Since the reform and opening up, with the continuous development of the national economy, national culture, and entertainment living standards, our understanding of popular music has been updated and deepened [3]. Since the birth of Jazz in the 19th century, this nascent art form has incorporated more forms and possibilities and has integrated cultures from different regions in a century of development. Major music schools in China have made active efforts in the subject of popular music and have achieved certain developments. This paper integrates the teaching strategies of semifinished products to construct a multimedia pop music teaching system and evaluates the teaching effect of the system, so as to provide a theoretical reference for the follow-up pop music teaching
