Blue Sky

Why it sounds this way

Blue Sky is a happy chord progression that moves I – ii – IV – V (C Dm F G in C). The feeling walks home → wander → open → 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 “big blue sky.” Play it on piano or guitar above, and switch keys if you want it higher or lower.
