BP Neural Network and Computer Virtual Reality Technology in Piano Performance Practice

As an ancient musical instrument, piano plays an indispensable role in people's daily life. With the development of science and technology and the improvement of living standards, people's aesthetic demand for it also increases. And virtual reality technology can provide users with a new three-dimensional and realistic visual and auditory experience. This paper will introduce a new digital music playing method based on the combination of BP neural network and computer virtual reality system, and how to use MATLAB software to realize piano simulation in the future work. The test results show that, The piano performance system based on BP neural network algorithm and computer virtual reality technology can process more than 80% of the piano score data efficiently, and the maximum number of piano pieces stored can reach 6574k. Based on the above test results, it can be seen that the system can meet user requirements.
