The cat piano maps a chromatic scale of pitched meow samples onto segments of a cat illustration. Tap different parts of the cat's body to play notes across two octaves, with each segment colored by its interval when a chord is selected. Low notes sit near the belly and tail, while higher notes are near the head and ears. It is a fully functional chromatic instrument -- every chord type in ChordColor's 528-chord library works on the cat, with proper interval coloring and audio playback.
Despite the playful concept, the cat piano demonstrates a real music theory principle: intervals sound the same regardless of the timbre producing them. A major third between two meow pitches has the same bright quality as a major third on piano or guitar. The color coding is identical to every other instrument in ChordColor, so the harmonic relationships you learn on the cat transfer directly to serious instruments.
The cat piano is designed to make music theory approachable. Teachers use it to introduce young students to the concept of intervals in a way that holds attention. The 12 pitched meows form a complete chromatic octave, so students can hear the difference between a minor second (two adjacent meows) and a perfect fifth (seven semitones apart) in a context that feels like play rather than study.
