Natural bitumen pitch, from the tar pit above the McKittrick Oil Field, Kern County, California. Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid ...
In modern Western music notation, a natural (♮) is a musical symbol that cancels a previous sharp or flat on a note in the written music. The natural indicates that the note is at its unaltered pitch .
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
Natural bitumen from the Dead Sea Refined bitumen The University of Queensland pitch drop experiment, demonstrating the viscosity of bitumen. Bitumen (UK: / ˈ b ɪ tʃ ʊ m ɪ n / BIH-chuum-in, US: / b ɪ ˈ tj uː m ɪ n, b aɪ-/ bih-TEW-min, by-) [1] is an immensely viscous constituent of petroleum.

Meaning respectively "measured song" or "figured ...
Pitch is a perceptual property that allows sounds to be ordered on a frequency-related scale, [1] 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. [2] Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre ...
In most cases, a sharp raises the pitch of a note one semitone while a flat lowers it one semitone. A natural is used to cancel the effect of a flat or sharp. This system of accidentals operates in conjunction with the key signature, whose effect continues throughout an entire piece, or until another key signature is indicated.
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.
