You can change the pitch of a vibrating object by altering its tension, such as tightening or loosening a guitar string. Another way is by changing the length of the vibrating portion of the object, like pressing down different frets on a guitar neck.
Replace the nitrogen & oxygen air with helium and oxygen. tighten the tension on the vibrating thing (e.g., string) make the vibrating thing smaller, thinner. (e.g., tuning fork)
Apply a force that causes the object to oscillate. Use a motor or vibrating device to generate vibrations in the object. Strike or hit the object to induce vibrations. Apply sound waves to the object at its resonant frequency to make it vibrate.
When a force is applied to an object, it can change the object by accelerating it (changing its velocity), deforming it (changing its shape), or moving it (changing its position).
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
An object can accelerate by speeding up (increasing velocity) or by changing direction (experiencing a change in acceleration).

To change density there are three ways. You can change the shape, mass or volume of the object
When a force is applied to an object, it can change the object by accelerating it (changing its velocity), deforming it (changing its shape), or moving it (changing its position).
Decrease the mass, and change the force.
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
you can either change the volume or the mass
An object can accelerate by speeding up (increasing velocity) or by changing direction (experiencing a change in acceleration).
Mass can change by adding or removing material from an object. This can either increase or decrease the mass of the object. Additionally, mass can change through physical or chemical reactions where the composition of the object is altered.
Conduction can occur through direct contact between objects of different temperatures, where heat is transferred from the warmer object to the cooler object. It can also happen in solids, where vibrating molecules pass on kinetic energy to neighboring molecules.
force's can change the speed, shape, size and direction of an object.
Accelerating an object by increasing its speed. Slowing down an object by reducing its speed. Changing the direction of an object's motion. Stopping an object from moving. Inducing rotation in an object.
