I am a student of music education from the Conservatory of Music. For this semester, I feel that online class is the most unforgettable one for me. Since I was a child, I have never experienced this form of class. Although online classes can't avoid watching online classes, this way is very unfavorable for music students; Because piano and vocal music courses are limited, they can't play to their normal level. It is also beneficial that videos that are not understood in class can be played back and watched. Anyway, there are advantages and disadvantages. Think about it in perspective, because the illness can be well presented now from what was impossible before.
