Air particles do not travel in any motion. They oscillate around a point in space. The rate of this oscillation is known as the frequency of the sound wave and is denoted in cycles per second (cps) or hertz (Hz). The amount of compression/rarefaction of the air is the amplitude of the it.
Sound is a vibration that generates an acoustic wave. The distance between consecutive peaks of compression or rarefaction is the wavelength of the sound wave (denoted by λ). Fast traveling wave results on a greater λ

When we make music, we need to define a set of tuning-frequencies. Such a set of frequencies often called a scale. Before get into the topic MIDI & equal tempered scale we will discuss on basics.
In western music, the most popular scale is the equal tempered scale which is based on starting at some reference-frequency. The equal tempered scale is relatively fixed scale used for the tuning of pianos and other instruments.

Sound is created by vibrations. In music world , all musical instruments creates different type of sound wave vibration. The Pitch is the frequency of sound wave vibrations and measured in hertz (abbreviated Hz).
Frequency is the number of waves that pass a given point in a certain amount of time. In other word , the total number of vibrations or oscillations made by the particles per unit time is called the Wave Frequency.
