          The purpose of this research was to compare the optimum legibility of musical notations in blue, green, red and black colors in reading notation of marching band musicians in secondary schools.
          The subjects were 60 clarinet players of marching band in secondary schools. The subjects were classified into two groups; low and high experience in playing music group. There were 30 subjects in each group. The subjects were diagnosed by Snellen eye chart and a color blind test (Ishihara Test)
          The subjects were tested one by one by playing the clarinet from reading musical notations on march card, and the songs they played were four new songs. Each song was on one white card and recorded the musical notations on the black staff in one color of; blue, green, red and black. One mistake was counted as one point deducted from the total score of 100.
          The scores, then were analyzed by one – way analysis of variance with repeated measure at the 0.01 of level significance. The Tukey’s HSD test was used for pairs – wise analysis.
          The findings indicated that green musical notations and blue musical notations provided more optimum ligibility of marching band musicians in secondary schools than black musical notations and red musical notations at the 0.01 level of significance. There was no significant differences between green and blue; and between black and red.
