Description

technical field [0001] The invention relates to the technical field of piano learning devices, in particular to a piano learning device that is easy for students to carry around. Background technique [0002] As we all know, the piano is very heavy, and its corners are very brittle and easily scratched, leaving scratches and dents. Even a small upright piano weighs more than 0.1588 tons. Grand pianos can weigh up to 0.4536 tons, and old upright pianos are often very heavy, making them very unstable and more difficult to carry. Therefore, for people who study music, they can only learn to play the piano in the piano room, and it is impossible to learn to play the piano at any time. Playing the piano anywhere restricts piano learning; in addition, the general cost of piano learning is high, but piano learners cannot practice playing anytime and anywhere on weekdays, which makes piano learning very inconvenient, learning efficiency is not high, and increases the burden of lear...

Problems solved by technology

Grand pianos can weigh up to 0.4536 tons, and old upright pianos are often very heavy, making them very unstable and more difficult to carry. Therefore, for people who study music, they can only learn to play the piano in the piano room, and it is impossible to learn to play the piano at any time. Playing the piano anywhere restricts piano learning; in addition, the general cost of piano learning is high, but piano learners cannot practice playing anytime and anywhere on weekdays, which makes piano learning very inconvenient, learning efficiency is not high, and increases the burden of learning; at the same time, for piano For learning, learners need to maintain the correct playing posture from the beginning. Players should use their eyes to read the score, their hands to find the keyboard, and occasionally use their peripheral vision to assist in finding the keyboard. In addition to lifting each finger, the most important thing is to use your fingertips when playing the piano, not with the belly of your hand, otherwise the speed will not increase quickly, and it will be very tiring to play, and it will be difficult to play. Flexible, it can be seen that for the initial practice of the piano, the practice of finding keys and fingering is the most important
