This article discusses the effects of a pitch feedback system integrated into Google Glass, called the MVP (Musical pitch Visualization Perception) support system, on the musical performance of wind instrumentalists. The study adopted the Goldsmith Musical Sophistication Index (Gold-MSI) to discuss the contribution of the MVP support system to the improvement of musical performance. The Gold-MSI is a popular tool in the field of music research that measures musical sophistication based on observable behaviors. The study reports the effects of the MVP support system from a quantitative standpoint, and the results show that the system had a positive impact on the participants’ pitch accuracy.

This article discusses the effects of a pitch feedback system integrated into Google Glass, called the MVP (Musical pitch Visualization Perception) support system, on the musical performance of wind instrumentalists. The study adopted the Goldsmith Musical Sophistication Index (Gold-MSI) to discuss the contribution of the MVP support system to the improvement of musical performance. The Gold-MSI is a popular tool in the field of music research that measures musical sophistication based on observable behaviors. The study reports the effects of the MVP support system from a quantitative standpoint, and the results show that the system had a positive impact on the participants’ pitch accuracy.
