AI Technical Summary
The existing erhu cannot accurately express frequencies below 293Hz, resulting in a loss of musical style. At the same time, learners lack music theory knowledge, which is a problem that is difficult to solve, especially when playing traditional pieces.
A dynamic tone reader for the erhu with twelve tones was designed. By combining a static tone name frequency base plate and a solfège strip, it provides dynamic tone name information to help beginners understand the modes and playing techniques, thus reducing the difficulty of learning.
It enables beginners to easily master the mode and pitch of musical pieces, reduces the difficulty of learning the erhu, and enables accurate performance of any piece of music.
