The lecture refutes the view mentioned in the reading with strong supporting evidences presented, aiming to further argue that it is essential for primary schools to invest on music.

Firstly, from the perspective of efficiency, the professor states his doubt, because according to the lecture, it explains that the students who have acquired music class have a better understanding as well as efficiency in reading and math.

Secondly, judging from cost, the professor holds a different view, because referring to the lecture, parents do not need to buy their children musical instrument individually, and on the contrary, the school will offer instrument and the instrument could be sustained for long.

Thirdly, on the point of practice meaning of music class, the professor never fails to express his concern, because in terms of the lecture, the sense of music will not decay with the time going, and this sense will ensure students a colorful life.

Therefore, our education should not limit the insight merely within the current effect.
