Frequency....

The rate of vibration of a sound wave,measured in hertz(Hz),which equals the number of complete vibrations per sound.The distance from a point on a angle on a similar point on the next vibration is called the wavelength,measured in metres.Different animals can hear different ranges of frequencies. 

A sound wave with a low frequency is heard as a low note,---a low pitch.As the frequency of a sound increases,the pitch of the sound increases.Musicians refer to the pitch of a note to describe how high or low it is.An oscilloscope is a device which displays various waves.

Amplitude....

The strength of a sound wave:loud sounds have a large amplitude.Sound producing objects that vibrate over a greater distance give sounds with a longer amplitude.The loudness of a sound is often described as its amplitude but they are not quite the same thing.The loudness of a sound depends on the hearing ability of the listener.A sound of a particular amplitude may sound loud to one person and quiet to another.

Intensity...

The distance as which a sound can be heard depends on its intensity,which is the arc rate of flow of energy per unit area perpendicular to the direction of propagation.Intensity varies inversely as the square of the distance in the actual propagation of sound through the atmosphere,changes in the physical properties of the air ,like temperature,pressure and humidity,produce damping and scattering of the directed sound waves :so that the inverse-square law generously is not applicable in direct measurements of the intensity of sound.

Quality/Timbre....

The quality of a musical sound depends on the precise shops of the waveform.The figure(a)below illustrates the waveform of a tuning fork.It is a pure sine curve.A musical instrument producing the same frequency is shown in Fig(b).The difference in shape is responsible for giving the instrument its particular quality.
