     But if you’re actually sleeping and you play something that you've already learned, like a piano melody you've been practicing, you may indeed master it more quickly. So says a study in the journal Nature Neuroscience.

     Researchers asked volunteers—with and without musical experience—to learn a few random¹ melodies on a computer keyboard.  Then the subjects took a 90-minute nap. When they slipped into slow wave sleep—a stage previously² shown to be associated with memory processing—the researchers softly played back one of the two melodies.

     After the subjects woke up, they were able to both melodies more accurately—the helpful effects of a little shuteye, the researchers say. But the volunteers did even better on the ditty they'd heard while snoozing, suggesting sensorimotor skills can be fine-tuned by exposure during sleep.

     The scientists stress that the procedure is no shortcut⁴ to becoming Scott Joplin—you still have to put in effort while awake. But a little sleep-time study may help you change your tune³ for the better.
