These 5 Tips Will Help You Solve Intonation Problems When Learning Any Instrument

1
Poor ear control
Reason for Mispronunciation: This mispronunciation cannot be heard by student himself. Honestly (the author was also first when he first started studying, but not now)
Solution: Teach him to listen to how he plays with your ears until he can understand what he is doing and what he is playing. These types of learners are able to interact more with their professional teachers and purposefully correct problems with many mispronunciations in a short period of time.
2
I don't know how to train in sections, practice is too mechanical
Reason for mispronunciation: I rehearsed piece over and over and didn't know how to stop and correct it in wrong place.
Solution: This method of practice is not scientific at all and takes too much precious time. I always don't know if I need to stop and fix wrong section and take it to practice alone so that I can practice effectively in a short time. (This is how author practices violin, and efficiency is greatly increased)
3
Too tall
Reason for mispronunciation: The practical repertoire is relatively complex, which is not directly proportional to level of student.
Solution: Excessive technical load leads to uncontrollable fingers of students. Students should contact teacher in time to check if songs assigned for homework are difficult, resulting in students' uncontrollable fingers.
4
Too much pursuit of speed
It doesn't matter what kind of music it is, if you're even a little familiar with it, you'll die quickly.
Decision: either play fast or play well. It is true that speed should be close to original speed, but before doing so, first thing to do is to play each note clearly. Make sound "thick" and "solid". Students who are desperately fast at any musical instrument need to play more, train, three times faster and one time slower. Look for completion in slowness and play notes clearly in fast.
5
The foundation is weak and there is a problem with spectrum recognition
Reason for mispronunciation: There are also reasons for teacher teaching. Many students have been studying for several years and they don't even recognize score. They all rely on memory to play.
Solution: Teachers and students are advised to lay a solid foundation and carefully solve problem of reading musical notation (the author's basic skills were not strong at beginning, and first half of lesson was a practice of basic skills and second half was a real lesson)

The above 5 points are especially helpful to me. Since then, I joined a symphony orchestra, got into a group and became a performer. I hope they will also be useful to violinists and friends who are learning other instruments.
