Years ago, when Charlie Parker died, numerous articles were published in testimonial to him. If memory holds true, one musician said of him, Bird never played an unresolved note in his life. No matter how fast he played, his music was still melodic and contained highly skillful resolution. Dr. William D. Revelli abhorred stagnant notes and would ask players to move notes including long tones, even in the accompaniment to give the music direction and keep the line alive. A melody played without direction and movement soon loses its appeal.
Singers have an added advantage through the use of words, which help to carry the line forward.
Attention to this one small nuance can help breathe life into a solo line or ensemble passage. Obviously, this last point requires sophisticated musical techniques and understandings and a good music dictionary. Students need to grow steadily to a point where they are able to go beyond the mere notes and incorporate musical nuances into their playing. Teachers must lead the way. Having stressed these musical nuances throughout my entire teaching career, both with individuals and ensembles, I have seen tremendous musical growth as a result.
