First of all, piano training teachers need to master standardized playing methods. Teachers need to deeply understand and master the correct hand shape, posture, playing methods and knowledge about aesthetic concepts, and can effectively guide students to master the correct and standardized playing methods in teaching. If there is something wrong with students' learning methods, it will be difficult to learn piano.

Secondly, piano training teachers need to have good musical literacy. Good music literacy is the basic condition for engaging in the music industry and also the basic condition for success. If teachers don't have good musical literacy, how to help students lay a good foundation in music, and even more can't correct children's intonation and rhythm problems, students' musical literacy and musical sense will not be improved, which will inevitably affect students' future development.

Then, piano training teachers should have profound artistic accomplishment. Only when teachers have good artistic accomplishment can they be sublimated in students' performances and provide further processing and transformation. Otherwise, students' artistic quality is rough, their performance quality is low and they are not competitive.

Finally, piano training teachers should have good teaching ability. Teachers should face students of different ages and personalities, adopt different teaching methods, understand students' psychological conditions, mobilize students' enthusiasm and desire for knowledge to the maximum extent, and let students develop along the fixed teaching content in order to achieve the corresponding teaching objectives.

A piano teacher with the above four abilities, plus a strong sense of professionalism and responsibility, will become an excellent piano teacher.
