Paper charts still teach what screens hurry past

Screens invite constant zooming. Zooming invites new swings that were invisible a moment earlier. Paper fixes the window: the week is the week, the pencil commits, and the eraser shows how often you change your mind.

We are not nostalgic for its own sake. After students struggle with a printed channel, they return to their charting package with clearer rules about which timeframe owns the line. The tablet becomes a place to apply the habit, not a place to invent a new geometry every hour.

If you practise at home between lessons, print one weekly chart of an instrument you hold. Draw once. Leave it on the desk until the week ends. Compare your marks with what actually happened before you redraw anything.
