Sing a new song to him. Play beautifully and joyfully on stringed instruments. Psalm 33:3 (God's Word Translation)
The closest thing to a piano in Biblical times was a lyre and harp, and that's really, really stretching it. But in the spirit of that verse in Psalm 33, I would like to share this video post from Time.com about a public art program called Play Me, I'm Yours. This summer, 60 pianos were placed throughout New York City as part of an effort to encourage people to play music. (Sorry for the brief opening commercial. It comes with the video).
