Abstract
Introduction : Activities that require the use of both hands simultaneously require that the two movements have the same spatial and temporal characteristics. Doing two incompatible tasks at the same time often leads to interference at the behavioral level.

P urpose : The purpose of this research was to investigate the effect of training with music on coupling bimanual tasks.
Methodology : The current research was semi-experimental. The tools used included the bimanual coordination measuring device, laptop , Edinburgh handedness questionnaire, hands-free and music with two different tempos. The participants were students (age range 15-17), who were in three groups of 16 (exercise with high tempo music: 120 beats per minute, exercise with low tempo music: 90 beats per minute, and exercise without music) were placed. In the pre-test, they performed four bimanual coordination tasks with different difficulty, including circle-line drawing. In the practice, only the task of the right hand - circle was done in the clockw ise direction and the left hand- horizontal line. The exercises were performed in 4 blocks of 10 trials three days in a row. Each test-like effort was performed for 30 seconds. A memory test was performed immediately in the post-test and 48 hours later. Mixed analysis of variance and one-way ANOVA and Bonferroni follow-up tests were used. Data analysis was done using SPSS version 22 software at a significance level of 0.05.

Findings : The results showed that practicing with music in simpler tests had a greater effect on learning the bimanual circle-line drawing task, but no difference was seen between the groups in the difficult task. The findings also showed that in the training group with high-tempo music, there was a negative transfer in the time pattern of the non-dominant hand in performing the difficult bimanual task.

Conclusion : In general, after practicing asymmetric bimanual movement, stronger temporal coupling than spatial coupling occurred. The higher the tempo of the music during the exercise, the higher the coupling rate. Overall, movement educators are advised to use up-tempo music for learning motor coordination tasks, especially learning temporal patterns.
