[0002] The piano has always been an extremely important instrument in the existing music teaching, performance and creation process. Its expressive sound quality and musical characteristics make it an important instrument in various music activities. However, for beginners or pianists who are practicing specific music, it is often a big challenge to accurately and quickly find and press the correct keys, understand the relationship between keys and notes, and especially to accurately identify and give feedback in real time during performance.

[0003] Traditional piano teaching and practice methods mainly rely on paper scores and teacher guidance, while modern piano teaching is trying to introduce digital technology, using various auxiliary tools, software or applications to help performers obtain more intuitive visual feedback and learning guidance. In many application scenarios, providing intuitive feedback on key positions, correct playing order, speed, etc. has become the key to improving learning and practice efficiency.

[0004] Some existing solutions, such as electronic keyboards and smart piano teaching software, although they provide visual assistance and interactive learning experience to a certain extent, are often accompanied by many shortcomings. For example, these solutions usually require specific hardware devices or software platform support, are not flexible enough; real-time performance and accuracy still need to be improved; and are not compatible and portable with traditional pianos. In addition, they may not be able to intuitively display the dynamic changes of the keys, and give the performer accurate and timely feedback during the performance to guide their more precise movement adjustments and rhythm control.
