The song is a unit and each phrase contains a definite idea, therefore it must not be detached or fragmentary, but must have the element of continuity and each and every part must be made to contribute to the central idea.
The element of insecurity must not be allowed to enter. If it does, the listener feels that the singer is not sure of himself, that he cannot do what he set out to do: therefore he is a failure.
Another demand is that the singer shall be intelligent. A poem does not lose its meaning or its strength by being associated with music, and to this end the singer must deliver the text with the same understanding and appreciation of its meaning as would a public reader.
Now from the above we infer certain principles. The demand for continuity means that the singer must have a pure legato. That is, he must be able to connect words smoothly, to pass from one word to another without interrupting the tone, that the tone may be continuous throughout each phrase.
The feeling of security lies in what is known as sostenuto, the ability to sustain the tone throughout the phrase with no sense of diminishing power. It means in short the organ time.
From the demand for design in each word and phrase comes contrast. This may be made in the power of the tone by means of cres. dim. sfz. It may be made in the tempo by means of the retard, accelerando, the hold, etc. It may also be made in the quality of the tone by using the various shades from bright to somber.
The basis of phrasing then, may be found in legato, sostenuto and contrast. All of the other things involved in interpretation cannot make a good performance if these fundamental principles be lacking. A more complete outline of interpretation follows:
