Intuitive, Interactive Training System for the Sense of Sound Using Portable Theremin Device

The study investigats an interactive Theremin sound pairing assessment system aimed at realizing an intuitive pitch training platform. Utilizing algorithms designed to detect user-controlled pitch and instrument selections, this system facilitates the display of user-friendly information on terminal devices, including portable PCs. Notably, this device achieves a substantial reduction in size and weight compared to the traditional Theremin. It boasts the distinctive, intuitive, air-touch playing characteristics inherent to the Theremin, eliminating the barriers typically associated with learning musical instruments or vocal techniques. Furthermore, it combines educational and entertainment features. Various sound perception feedback methods are explored to create an interactive environment that enhances motivation for practice. The research findings indicate that perceptual skills, such as pitch and timbre discrimination, can be acquired intuitively and visually, obviating the need for a theoretical foundation.
