Intonation is often one of the standards by which judges rate a competition performance.
This subjective and important aspect of music and the means for perfecting it are left largely to the resources of the school band director. Very little in constructive and concrete method has been developed to make the band director's task of improving intonation easier. Since the sound of a musical aggregation rests heavily upon this element, intonation and its improvement remain at the top of the director's list of perplexing problems. A faulty conception of pitch may cause students to believe that they are playing in tune and, as a result, directors find themselves spending a disproportionate amount of their time analyzing and correcting the causes of poor intonation. Using a strobe tuner, students are able to see the evidence of their errors.
