The Design And Implementation Of Virtual Dulcimer System

Instrumental music teaching is an important part of music teaching,it play an important role for enhancing people’s music literacy and aesthetic ability.However,in the traditional instrumental music teaching,due to the price of musical instruments,venues,lack of teachers and other factors,instrumental teaching is in a single way,a lot of teaching activities can’t be carried out,to a large extent limit the development of instrumental music teaching.With the virtual reality technology,multimedia technology and computer music technology continues to develop,virtual instruments and virtual music software emerge in endlessly,and instrumental music teaching ushered in a new opportunity.But most of the current virtual instrument software are mainly for western musical instruments,such as piano,guitar,very few for our traditional national musical instruments.Moreover,the existing virtual instrument software mainly to entertainment,it can’t be directly applied to instrumental music teaching.In view of the above background and the problem,we not only study the key problems in the development of virtual dulcimer based on the theory of dulcimer music teaching but also design and realize the virtual dulcimer system of auxiliary dulcimer teaching.Works as follows:(1)Research on the related literature of virtual instrument.By studying the theoretical and technical basis of the research and development of the virtual instrument,we can consult the domestic and foreign literature,clear the present situation of the development of the virtual instrument,and then get the research content,method and basic research ideas of the paper.(2)Research on key problems of virtual dulcimer system.The construction of the virtual dulcimer model:analyzing the structure of the dulcimer of the entity,combining the dulcimer teaching needs,constructing the virtual dulcimer model;The acquisition of timbre of virtual dulcimer:the use of two kinds of construction methods,the traditional dulcimer sound and MIDI digital dulcimer sound;The realization of virtual dulcimer automatic performance:parsing MIDI files,triggering sound animation synchronous playback;User performance evaluation analysis:studying the existing music evaluation model,putting forward the user performance and standard performance matching model,and then using the model analysis music data,to provide feedback for the users.(3)Design and Realization of Virtual Dulcimer System.Starting from the goal of the project,combined with the needs of modern users on the virtual dulcimer system needs analysis,according to the needs of the design and implementation of the overall system framework and functional modules.(4)Test and Analysis of Virtual Dulcimer System.The system used case detection and user experience survey to prove the effectiveness and practicality of the system.In summary:According to the characteristics of dulcimer performance,this paper designs the performance interface and function modules of the virtual dulcimer system,and uses WPF technology to achieve multi-point playing under the Window flat.And according to the content of dulcimer users,compared with the standard music in the template library,to provide users with teaching feedback.
