sound that you hear as a tone is made of regular, evenly spaced waves of air molecules. The most noticeable difference between various tonal sounds is that some sound higher or lower than others. These differences in the pitch of the sound are caused by different spacing in the waves; the closer together the waves are, the higher the tone sounds. The spacing of the waves - the distance from the high point of one wave to the next one - is the wavelength.
All sound waves are travelling at about the same speed - the speed of sound. So waves with a longer wavelength don't arrive (at your ear, for example) as often (frequently) as the shorter waves. This aspect of a sound - how often a wave peak goes by, is called frequency by scientists and engineers. They measure it in hertz, which is how many wave peaks go by in one second. People can hear sounds that range from about 20 to about 17,000 hertz.
The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound
Pitch is the perception of the frequency of sound. For this perception no propagation through the air is necessary, for instance in case of bone conduction, or pressing your against a door. Usually, however, propagation takes place through air, and is the notion of wavelength relevant: it is immediately connected to frequency. [I disregard the influence of sound velocity; it varies little and can be neglected here.]
But the perception is based on frequency, not on wavelength.
What is pitch of a sound?
Pitch can be taken as the measure of sound frequency expressed in terms of Hertz. Higher the frequency, higher the pitch. All kinds of sound produces some waves that are measured with respect to the frequency it carries. Pitch can also be expressed as the position of a musical note in a musical scale. So note in the lower side is a low pitch sound and vice versa.
Following points may be noted:
Each musical note has an unique frequency hence each having different Pitch. This differentiate the nature of sound between Keys.
There are 7 ( 12 with sharp & Flats) different sounds due to seven different frequencies and if arranged in ascending order the pitch will be rising when we progress from a low key to high.
On eighth note of each key the frequency gets doubled. The result is increase in Pitch but without changing the nature of sound. This is called change in Octave.
Every higher octave will carry relatively higher pitch and frequency which are twice the frequencies
The frequency at which the airwaves are resonating (measured in Hertz: 1Hz means the object measured is vibrating/moving back and fourth once per second) is the pitch of sound and of course different sound have different pitches, that’s what music in example is all about: changing the pitch to create notes with which to compose melodies and harmonies
