Each instrument possesses its own timbre and uniqueness. So does each performer have their own personality and uniqueness. We are all different.In the ensemble setting, if individual members are only thinking about themselves, it is difficult to blend differing timbres. The blend and balance of the group can be improved tremendously by coming closer on both the instrumental and personal levels. Understanding how to adjust to surroundings and overcome this individuality is a major factor in making music. "Yuimar" in Okinawan dialect means "collaborative work or assisting one another". As this word explains, I hope this work creates the opportunity for an amazing collaborative work in music making. Music available in flexible instrumentation for trio.
