Hollow by Stray Kids — Easy Piano for Kids

This page shows “Hollow by Stray Kids 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 C at 106 BPM, a medium-difficulty arrangement — try slowing the tempo down using the BPM control.

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.

Teacher’s notes

This arrangement sits in a comfortable mid-tempo groove at 106 BPM, but don't let that fool you into coasting — the real challenge here is maintaining a steady, emotionally driven rhythm in your right hand while your left hand handles chord transitions that occasionally shift on off-beats. You'll work with familiar pop chord shapes in C, but pay close attention to any minor chord voicings that color the verses; those transitions from major to minor can trip you up if your fingers aren't already hovering near the right keys. Start hands-separate at about 70 BPM, focusing first on locking your left-hand chord changes to a metronome before layering in the melody. Once you combine hands, loop the chorus separately — that's where the rhythmic density picks up and syncopation between hands tends to cause hesitation. Use light sustain pedal, changing cleanly with each chord to avoid muddiness. The most common stumble I see is rushing through the pre-chorus to "get to the good part," so deliberately slow that section down until it feels almost boring. This is a fantastic piece for training your hands to stay rhythmically independent, a skill that will pay off in every pop arrangement you touch from here on.
