"A Violin at Dusk" by Lizette Woodworth Reese (d. 1935) was offered by Poets.org's Poem-A-Day on November 16, 2013. A link to the poem may be found here:
The poem is in the form of a rhyming Italian sonnet with a mainly dactylic tetrameter rhythm. There are puns on the words "fret" (meaning to worry but also part of a violin), and "springs" (meaning the season but also part of the tuning mechanism of a violin), and "hand's width" (the distance lit by the candle in the poem but also referential to the hand's reach across a violin). The somber music of the violin causes the speaker, presumably the poet, to "think of young, lost things."
