Technical Field

[0001] The present application relates to the technical field of music teaching, and in particular to a piano fingering trainer and a method thereof. Background Art

[0002] As we all know, the piano is the king of musical instruments, and the price of the piano is very high. Therefore, piano teaching is usually equipped with only one piano. When there are multiple students, the students can only take turns to play. Moreover, most students do not have a piano at home. Therefore, during the period when the piano cannot be played during piano teaching, and when there is no piano at home, the students cannot conduct effective training, which wastes time and is not conducive to piano learning. When practicing the piano, it is generally necessary to judge whether the keyboard keys and fingers are used correctly. Therefore, a piano finger training device is needed for piano training and learning. At present, the piano finger trainers sold in piano stores have the problems of complex structure, difficult operation and high production cost.
