If this is the excerpt:
<span><span>Heard melodies are sweet, but those unheard </span>
Are sweeter; therefore, ye soft pipes, play on;
<span>Not to the sensual ear, but, more endear'd, </span>
<span>Pipe to the spirit ditties of no tone: </span>
<span>Fair youth, beneath the trees, thou canst not leave </span>
<span>Thy song, nor ever can those trees be bare; </span>
<span>Bold Lover, never, never canst thou kiss, </span>
<span>Though winning near the goal yet, do not grieve; </span>
<span>She cannot fade, though thou hast not thy bliss, </span>
For ever wilt thou love, and she be fair!
</span>
Then the part that reflect the theme that art is immortal is
Though winning near the goal yet, do not grieve;
<span><span>She cannot fade, though thou hast not thy bliss,
</span>It implies that there is no need for grieving because She cannot fade. She will last for a long time.</span>
