Two experimental studies have been conducted in order to propose practice indexes for the improvement of the embouchure of French horn players, two experimental studies have been conducted. In both studies, the same task was performed by advanced and amateur French horn players. The first study investigated the activity, while performing the above-mentioned task, of the 5 facial muscles (levator labii superioris, zygomaticus major, depressor anguli oris, depressor labii inferioris, and risorius muscles) on the right side of the face by surface electromyography, and the facial movement on the left side of the face by attaching two markers above each muscle and using two high-speed cameras simultaneously. The results of the study showed that it is possible for the four markers around the lower lip to practice indexes. The second study evaluated whether the above-mentioned markers are appropriate as practice indexes using a 3-D tracking system and questionnaires. The results showed that both the advanced and the amateur players assessed that the markers were suitable as practice indexes for improving the embouchure. This set of approaches could be useful for selecting practice indexes and developing scientific practice methods not only for the French horn but also for other instruments and other fields.
