The other unique element to the SL live concert experience is the accessibility of artists. Performers can view text messages and questions. Artists customarily engage the audience before and after concerts and sometimes at breaks in the program. This accessibility is as rewarding to the performer as to the audience. The use of virtual reality for musical education is relatively new but music educators are already discovering that the ability to have students view text while they listen to music helps deepen understanding. In one recent music appreciation class, students were able to read text information about what they were hearing during the performance.
