Catchy is a happy chord progression that moves I – IV – vi – V – I – IV – ii – V (C F Am G C F Dm G in C). The feeling walks home → open → longing → tension → home → open → wander → tension. Most of these are plain triads, so the colors feel direct and the outline stays clear. That matches a small tip for this mood: major chords + a push home. That is why it fits a scene like “humming on the school bus.” Play it on piano or guitar above, and switch keys if you want it higher or lower.
