A life, in Sara Teasdale’s eight-line lyric, is a musician. The speaker does not describe a dramatic event but an intimate, recurring sound: “a certain tune that my life plays.” From the first line, the poem sets up a paradox between certainty and fragility—certain because it is known and repeated, fragile because it always dies away. The tune begins with the “wavering loveliness of viols,” speeds up like a “runner’s heart,” climbs beyond time and doubt, pauses in an almost heavenly solitude, and then “faltering blindly down the air, goes out.” The central idea is not simply that joy or inspiration is fleeting; it is that this rise and fall is a shape the speaker has learned to recognize, even to expect.
The construction enacts that shape. Two quatrains hold the whole movement in two sentences. The first stanza carries the music from first hearing to swift acceleration; the second completes the ascent and records the fall. Rhyme is understated: the second and fourth lines of each stanza chime quietly—“start” with “heart,” “doubt” with “out”—while the first and third lines remain open, as if the poem itself will not settle too securely. The loose iambic pulse gives the lines a heartbeat, but the phrase “Over and over” in the second line breaks any stiff regularity, mimicking the way a tune returns with small changes each time. Enjambment between “viols” and “And gain in swiftness” hurries the eye forward, much as the music gathers speed.
Imagery makes the tune almost visible and bodily. It is not only heard; it is watched. The speaker says “I watch it sway in climbing,” turning sound into a moving figure in the air. The simile “like a runner’s heart” brings the pulse of physical exertion into the music, so the tune becomes both external art and inner life. The word “wavering” is particularly precise: it suggests vibrato, hesitation, and beauty that trembles on the edge of losing itself. Then the poem lifts the concrete into the abstract: “High over time, high even over doubt.” The doubling of “high” pushes the ascent beyond ordinary limits, and “all heaven to itself” gives the moment a solitary, breathless completeness. Yet at the point of greatest height the poem introduces a pause, and the final line lets the music disintegrate in slow motion. “Faltering blindly down the air” is full of falling movement and failing control; the closing “goes out” is quiet and final, like a candle or a last breath.
What makes the lyric significant is its compression. In eight lines Teasdale traces an entire emotional curve—anticipation, acceleration, transcendence, suspension, loss—without explaining it. The lack of a named cause for the tune matters. It may be creative inspiration, love, hope, or a moment of spiritual clarity; the poem deliberately keeps it general so that the reader can recognize the pattern in many kinds of experience. At the same time, “over and over” prevents the ending from feeling merely sad. The speaker does not say the tune is gone forever, only that it has gone out again. Its recurrence is as certain as its fading. That mixture of recognition and resignation gives the lyric its quiet power. It suggests that a life can be understood not only by what it achieves or keeps, but by the transitory music it returns to, listens to, watches climb, and lets go.
