sweet little girl named Molly lives. Molly is six years old and has a younger brother named Wilson. Molly and Wilson love to play together, but when it's time for bed, Molly struggles to fall asleep.

One night, as Molly lies in bed, she hears a soft melody coming from her room. She sits up and hears her keyboard, who is named Peter Piano, playing all by himself! Molly is surprised but also excited. She listens as Peter Piano plays beautiful songs. Each note is like a gentle lullaby that makes her feel calm and sleepy.

Peter Piano plays songs for Molly and starts teaching her about music. He shows her how to play different notes and chords. Molly is a quick learner, and soon she is playing simple children's songs on Peter Piano.

The next night, something even more magical happens. The acoustic guitar that hangs on her wall starts to play along with Peter Piano. The guitar also has a name - Guy Guitar. Together, Peter Piano and Guy Guitar create beautiful music that fills Molly's room.

Molly is thrilled! She spends her nights learning to play both Peter Piano and Guy Guitar. She practices and practices until she can play many songs. She loves the feeling of the keys under her fingers and the strum of the guitar strings.

From that day forward, Molly uses her music to help her fall asleep. She plays a soft lullaby on Peter Piano and Guy Guitar, and soon she drifts off to dreamland. She even plays for Wilson during his nap time, and he too falls asleep to the sound of her music.

And so, Molly's room becomes a place of magic and music. Every night, Peter Piano and Guy Guitar come to life, filling the room with beautiful melodies. And every night, Molly falls asleep to the sound of her own music, dreaming of new songs to play and new adventures to have with Peter Piano and Guy Guitar.
