(In much the same way, the term "10 degrees" can label both a temperature and the distance between two temperatures.) Only one of these labelings is sensitive to the (arbitrary) choice of pitch class 0. For example, if one makes a different choice about which pitch class is labeled 0, then the pitch class E will no longer be labeled "4".

Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar , or from plants, as in pine tar .
Pitch (music), the perceived frequency of sound including "definite pitch" and "indefinite pitch" Absolute pitch or "perfect pitch" Pitch class, a set of all pitches that are a whole number of octaves apart; Relative pitch, the ability to identify a given musical interval between two notes; Pitch accent, a form of accentuation in speech
Absolute pitch is the ability to perceive pitch class and to mentally categorize sounds according to perceived pitch class. [38] A pitch class is the set of all pitches that are a whole number of octaves apart. While the boundaries of musical pitch categories vary among human cultures, the recognition of octave relationships is a natural ...
A pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. "Pitch" is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen, also known as asphalt. At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
A common tone is a pitch class that is a member of, or common to, a musical scale and a transposition of that scale, as in modulation. [1] Six of seven possible common tones are shared by closely related keys , though keys may also be thought of as more or less closely related according to their number of common tones.
The chromatic circle, the outer level of Lerdahl's model of pitch-class space. In music theory, pitch-class space is the circular space representing all the notes (pitch classes) in a musical octave. In this space, there is no distinction between tones separated by an integral number of octaves. For example, C4, C5, and C6, though different ...
