Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies.

A quick definition: Combine the name of the pitch (letter) with the octave the pitch is in (number). This letter and number combination is the "scientific pitch notation" and indicates a precise pitch. For example, C4 = Middle C on the piano. C4 refers to this exact C, not a lower or higher C.

For example, if you strum the thinnest string on a guitar or strike a note to the far right of a piano keyboard, you will hear a relatively high pitch. If you strum the thickest guitar string or play the key farthest to the left on a piano keyboard, you will hear a relatively low pitch.

American Standard Pitch Notation (ASPN) provides labels for specific musical frequencies by combining a note name (such as C) with a subscript octave designation (such as 4). A pitch is a discrete tone with an individual frequency (e.g. C4), while a pitch class is less specific (e.g., C in general).

So in a nutshell pitch is how high or how low a specific note sounds to the human ear pitch is the frequency of vibrations. As they go through a sound wave.

The pitch of a sound is our ear's response to the frequency of sound. Whereas loudness depends on the energy of the wave. In general, the pitch is the reason behind the difference in voice quality of different individuals.

There are only seven note names (A, B, C, D, E, F, G), and each line or space on a staff will correspond with one of those note names. To get all twelve pitches using only the seven note names, we allow any of these notes to be sharp, flat, or natural. Look at the notes on a keyboard.

There are only seven letters in the musical alphabet: a, b, c, d, e, f and g.

Western music typically uses 12 notes – C, D, E, F, G, A and B, plus five flats and equivalent sharps in between, which are: C sharp/D flat (they're the same note, just named differently depending on what key signature is being used), D sharp/E flat, F sharp/G flat, G sharp/A flat and A sharp/B flat.

The term pitch is most commonly used in British English, while the comparable term in Australian, American and Canadian English is playing field or sports field. For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles.
