The table above, shows that the average score of the pre-test and post-test of Experiment Class is 63.8 for pre-test, 75.4 of post test and 11.6 for gain score.
Afterwards, the next table is the result calculation of the Post Test Both Experiment Class teaching pronunciation using music songs and Control Class
teaching pronunciation without using music songs.

It shows that the score of both classes are on average level, it means that the student’s achievement in learning the Irregular Verb by using flash card is
generally high, though there are differences in minimum and maximum standard of each class, the table shows the experiment class has higher
standard. From the table above the writer gets the calculation using that, test formula;

5.89 or 2.7 2.02 5.892.7
j. The comparison between t-score and t-table :
In the table of significance or in t-table, we can see on the df = 38 and on the degree of 5 and 1, the result is 2.02 and 2.7, t-score is 5.89, so we
can conclude that t-score is higher than t-table. SE

B. Lack Pronunciation
Pronunciation is importing element in English speaking skill. In other words no large pronunciation can make mistake to vocabulary. Someone may find
difficulties in English speaking. The tenth grades of SMK Cyber Media Duren Tiga South Jakarta are having kind of problem. They have difficulties in
understanding of the sentences. The problems approves concerning the results gained by the students in
the tests both oral and written. As it was presented in the table before, the results of the oral tests showed that there is only 3 of all students got the high score,
26 of them got the middle score, and 71 got the low score. Meanwhile, the table of the results of the students in written tests showed
that there is only 3 of all students got the high score, 28 of them got the middle score, and 69 got the low score. The results indicate that the students
have troubles in understanding the songs. In the oral tests, the writer provided eight items as an interview task. From
those eight, the students mostly could answer only the first and the second as they are familiar with those two items since they always meet them when the teacher
begins the lesson. Nevertheless, they could not comprehend the other items. This fact shows one again the problems in understanding the meaning of the sentences
or in other words the lack of pronunciation are approved.
C. Test of Hypothesis
The writers hypothesis described that there is significant with a song and writing. The statistic hypothesis states that if t
o
is higher that t
t
, it means that there is significant differences and H
a
is accepted. Meanwhile, if t
o
is lower than t
t
, it means that there are no significant differences or the same and H
a
is rejected, and H
is accepted. From the result of statistical calculation, it indicates that the value of t
o
is 5.89. The degree of freedom df is 38 obtained from N
t
+ N
2
- 2 = 20 +20 - 2. In this paper the writer uses the degree of significance of 5 and 1. In I he table
of significance of 5 and 1 the values of degree of significance are 2.02 and 2.71. Comparing the t
o
with each value of the degree of significance. The results is 2.02 5.89 2.71. Since t
o
score in the table is higher that t
t
score obtained from the results of calculating, the alternative hypothesis H
a
is accepted and the null hypothesis H
is rejected.
It means that teaching pronunciation with a song has a significance influence as seen from the result of statistic calculation from both experiment
class and controlled class, it can concluded that teaching has higher influence in teaching English for the first grade students of SMK Cyber Media Jakarta.
D. The Interpretation
Teaching with a song means to help the students to overcome their difficulties toward learning English grammar, especially the pronunciation in this
study. Using songs may become the alternative method in teaching the English, since it offers an interesting and enjoyable atmosphere of learning.
According to the result of hypothesis testing, it is known and true that using song can give a significant influence to increase students’ understanding. It can be
seen that the score of experiment class is higher than controlled class. The application of pronunciation shows that the writer presents here is for
the first grade of Vocational School students. However, it can also be applied to other grades of students of Vocational School, even for teenager’s classes, as long
as the context is suitable for the students. Teacher can create other activities which suit the theme in the school’s curriculum.
