Heard melodies are sweet, but those unheard Are sweeter; therefore, ye soft pipes, play on; Not to the sensual ear, but, more endear'd, Pipe to the spirit ditties of no tone: Fair youth, beneath the trees, thou canst not leave Thy song, nor ever can those trees be bare; Bold Lover, never, never canst thou kiss, Though winning near the goal—yet, do not grieve; She cannot fade, though thou hast not thy bliss, For ever wilt thou love, and she be fair! Based on the word choice, the speaker's overall tone is
1. angry.
2. encouraging.
3. mournful.
4. loving.
