Dust-covered boxes, old and forgotten furniture, and discarded treasures intrigue a young boy exploring his grandfather’s garage. In the midst of this mine, he makes a discovery more fascinating than a treasure: a guitar with a neck rising like a "black swan."

When Tata opens the guitar case that once belonged to his tata, a wealth of musical memories entrance the boy as the sound of the guitar strings transform "musty moths into beautiful butterflies." Tata tells the boy about the posadas at Christmas, birthday melodies and even shares his memory of a special moonlight serenade.

As his fingers glide along the frets, Tata paints the boy a picture of a world long-past. And with his grandfather’s help, the boy will learn to create his own musical memories for generations to come.
