Lyrics

How does she know that you love her?

How do you show her you love her?

How does she know that you real ly, real ly, tru ly love her?

It’s not e nough to take the one you love for grant ed.

You must re mind her, or she’ll be in clined to say:

“How do I know

he loves me?

How do I know

he’s mine?”

Well, does he leave a lit tle note to tell you you are on his mind?

Send you yel low flow ers when the sky is gray?

Hey.

He’ll find a new way to show you a lit tle bit ev ’ry day.

That’s how you know,

that’s how you know he’s your love.

That's How You Know by Stephen Schwartz — Easy Piano for Kids

This page shows “That's How You Know” by Stephen Schwartz in our color-coded kid songbook view — every note is colored by pitch (red C, orange D, yellow E, green F, blue G, purple A, pink B) and the lyrics sit directly under each note, so children can sing along while they play. The song is in the key of Bb at 140 BPM, a slightly more challenging arrangement — practice each phrase slowly first.

Tips for parents & teachers

  • Start at 50% tempo using the BPM control. Speed up only when your child can play through without stopping.
  • Turn on the metronome from the top bar to build steady rhythm.
  • Use the segmented OFF / C / 1 button to toggle note labels on the staff and keys — kids learn note names faster with letters showing.
  • Tap a measure number on the timeline to jump to a specific section for repeat practice.
