Movements along the aggregate demand curve are caused by changes in price level - real wealth effect, interest rate effect and open economy effect.
If some non-price level determinant causes total spending to increase/decrease then the curve will shift to the right/left - consumption, investment, government expenditure, net exports.

The model of aggregate demand and aggregate supply can be used to explain what would happen to the price level and output level of the economy in the short run if the government reduces taxes on imported consumer goods. This can be illustrated with a diagram. In the diagram, the aggregate demand (AD) curve is downward sloping and the aggregate supply (AS) curve is upward sloping. The equilibrium price level is determined by the intersection of the two curves. Initially, the equilibrium price level is P1 and the equilibrium output level is Y1. When the government reduces taxes on imported consumer goods, the aggregate demand curve shifts to the right. This shift is represented by the movement from AD1 to AD2 in the diagram. The new equilibrium price level is P2, which is lower than the original price level. The new equilibrium output level is Y2, which is higher than the original output level. In summary, the reduction in taxes on imported consumer goods leads to a decrease in the price level and an increase in the output level in the short run. This is due to an increase in aggregate demand.

If aggregate demand increases at every price level than the demand curve shifts to the right. In the short-run the new equilibrium forms from an increase in willingness to spend, thus higher prices and higher real GDP or quantity of output. If short-run aggregate supply increases at every price level than the supply curve shifts to the right. From the short-run to the long-run the new equilibrium forms from an increase willingness to sell, thus prices reduce to original equilibrium and output increases further. Recap: Prices stay constant while real GDP or total quantity of output increases.
