Work occurs when a force causes an object to move in the direction of the force.
Force changes either the speed or the direction of motion, or both.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Any change in the speed or direction of a moving object is called acceleration. It can be caused by applying a force in the direction of motion (speeding up), opposite to the direction of motion (slowing down), or perpendicular to the direction of motion (changing direction).
Acceleration is identified by any change in an object's speed, direction, or both. This can be observed by an increase or decrease in speed, a change in direction, or both. Acceleration is a vector quantity, meaning it has both magnitude (amount) and direction.
Well, it's often referred to as the direction of propagation of the wave.
The answer to your question is Work. The definition of work is: "When a force acts against resistance to produce motion in a body, the force is said to do work." - The CRC Handbook of Chemistry and Physics... Which means the exertion of a force on an object that produces motion in the direction of the force.
work
the exertion of force in a same direction; work can not be done without motion

Speed and direction is called velocity.

The direction of melody is simply called it's motion.
