A few nights ago I enjoyed some wonderful vocal music, with soloists and ensembles, some with instrumental accompaniment and others a cappella. A symphony can also make beautiful music without a word being sung or spoken, with every instrument working in perfect accord, with precise harmony and timing, eliciting a strong visceral response. A symphony orchestra or large ensemble takes a tremendous amount of coordination, cooperation and the direction of a talented conductor. It becomes a work of art when all of the parts are put together and guided by the hand of the master. Soloists, on the other hand, take control of their own music and interpret it as they choose. A masterful soloist can bring tears of emotion and bursts of joy.
