"Heard melodies are sweet, but those unheard
Are sweeter,"

is a pretty bit of hyperbole which involves a contradiction in terms.
An unheard melody is no melody at all, and as soon as we have music in
which a number of singers or instrumentalists are employed, the taste,
feeling, and judgment of an individual are essential to its
intelligent and effective publication. In the gentle days of the long
ago, when suavity and loveliness of utterance and a recognition of
formal symmetry were the "be-all and end-all" of the art, a
time-beater sufficed to this end; but now the contents of music are
greater, the vessel has been wondrously widened, the language is
become curiously complex and ingenious, and no composer of to-day can
write down universally intelligible signs for all that he wishes to
say. Someone must grasp the whole, expound it to the individual
factors which make up the performing sum and provide what is called an
interpretation to the public.

[Sidenote: _"Star" conductors._]

That someone, of course, is the conductor, and considering the
progress that music is continually making it is not at all to be
wondered at that he has become a person of stupendous power in the
culture of to-day. The one singularity is that he should be so rare.
This rarity has had its natural consequence, and the conductor who can
conduct, in contradistinction to the conductor who can only beat time,
is now a "star." At present we see him going from place to place in
Europe giving concerts in which he figures as the principal
attraction. The critics discuss his "readings" just as they do the
