“The beauty of the flute was in its simplicity, in its resemblance to the human voice. It always sounded clear. It sounded alone. The piano, on the other hand, was a network of parts—a ship, with its strings like rigging, its case a hull, its lifted lid a sail. Kestrel always thought that the piano didn't sound like a single instrument but a twinned one, with its low and high halves merging together or pulling apart.”
