Kammerton

The German word "Kammerton" refers to a "pitch" or "tuning standard," specifically the note A (usually A4) at a frequency of 440 Hz, which is commonly used as a reference tone for tuning musical instruments. The term is derived from "Kamm" (comb) and "Ton" (tone), as tuning forks (which produce this standard when struck) are sometimes pronounced through their prongs, resembling the structure of a comb.

For similar concepts, you might encounter terms like "Stimmtöne" (tuning notes) or "Stimmung" (tuning).

The difference lies in that "Kammerton" specifically refers to the standard reference pitch itself, while "Stimmtöne" is more general and can refer to any note used during the tuning process. "Stimmung" pertains to the broader concept of tuning as it relates to adjusting various pitches and tones of instruments.
