sound
Sound is a form of energy that is produced when objects vibrate and create compression waves through a medium like air. Sound energy can be heard and has the ability to travel through different mediums, but it is not considered matter itself.
A bell typically uses mechanical energy that is produced by striking or vibrating the bell itself. The sound produced by the bell is a result of this mechanical energy being converted into sound waves.
Vibrations are a form of kinetic energy, however the rate at which an object is vibrating is usually related to it's temperature.
it has kinetic energy = 1/2 mass x velocity squared
Thermal energy is the form of energy that measures temperature. It is the energy that comes from the motion of particles in matter, which determines the temperature of an object or substance.

For example thermal energy.
Thermal energy, or heat energy, causes molecules to move around quickly. As molecules absorb more thermal energy, they gain kinetic energy and their movement increases, leading to higher temperatures.

The only kind of energy that dark matter is -- well, MATTER. Or mass, if you prefer, which is the same thing. We don't know what KIND of matter this stuff is, hence the name "dark." The only two things we know about dark matter is that (1) it interacts with baryonic matter via gravity but (2) it does NOT interact with baryonic matter via the electromagnetic force or the strong force. At this point, we're still working on what type of matter would do that.

During burning, one kind of matter turns into its ash, gases, and heat energy. The chemical bonds in the matter are broken, releasing energy in the form of heat and light, and leaving behind the remains in the form of ash.
No one knows as yet, do they? But we sure as hell use it.
