Last year, He Jiayi was invited to our state as a judge of the harmonica competition and performed on tour, which was well received by the local harmonica music industry and the public. His superb piano skills left a deep impression on the local audience. His coming to perform this time will definitely create another sensation, which is also a blessing for harmonica music lovers in our state.
He Jiayi is not only an excellent harmonica player, but also an inventor of improving the harmonica. In 1985, he changed the traditional chromatic harmonica with 16 hole into 14 hole, but added two keys on the left side, and communicated with the keys behind the harmonica with a connecting rod, so that one hole of the harmonica could control eight tones. Therefore, this new harmonica is named l 12 chromatic harmonica. This achievement won him the first prize of China Edison's invention, and was also exhibited at the Bulgarian World Exhibition of Young Inventors.
