1 1,a) 2,3,b) 2,c) 1,d),,,,,.,.,. 2,.,,.,,,,, EMG The Relationship Between the Muscle Activities and the Musical Performance in Playing Trumpet Abstract: In this paper, we investigated the relationship between the muscle activities around the lips and the sounds of playing the trumpet. While one is playing the trumpet, it is important but also difficult to keep an embouchure. Previous studies have investigated the difference between muscle activities for register and proficiency, but these studies have not considered the player s playable register and the influence of experience playing other instruments. Thus, in this study we aimed to solve these problems by examining the surface electromyograms (EMGs) around the lips: the orbicularis oris superioris, orbicularis oris inferioris, depressor anguli oris, and levator anguli oris. As a result, we found that (1) muscle activity is greater in the high register than the low register, but muscle activities in the high register are not significantly greater than those in the low register for the wide range of the playable register in the fixed register (FR); and (2) a novice trumpeter has greater muscle activity in the upper lip than in the lower lip, while an expert shows no difference. The muscle activity is the same as for the novice player when a non-trumpet brass player plays the trumpet.
