The aim of the research is to identify the listening comprehension skills (direct comprehension, critical comprehension, and deductive comprehension) that require acquisition by sixth-grade primary school students, in addition to identifying the effect of employing the proposed concept in developing some musical listening comprehension skills among sixth-grade primary school students, as represented by the research problem. In the weakness of listening comprehension skills among sixth-grade primary school students, the research relied on testing listening comprehension skills as a research tool, where the descriptive approach was used to present the theoretical framework and previous studies, and the semi-experimental approach with the experimental groups, numbering 30 students, and the control group, numbering 30 students, and mental visualization was applied to the group. Experimental to measure the effect of the proposed visualization of the mental visualization strategy as an independent variable in developing listening comprehension skills as a dependent variable. The results indicated that there were statistically significant differences between the average scores of the experimental group students in the pre- and post-measurements of the musical listening comprehension skills test in favor of the post-measurement after applying the proposed visualization using... Mental visualization strategy.
