What is doh?

"Doh" can refer to a few different things, so I'll provide information on a couple of the most common meanings:

1. D'oh! (Exclamation):

   • This is a catchphrase popularized by the character Homer Simpson from the American animated television show "The Simpsons." It is typically used to express frustration, realization of a mistake, or when something goes wrong. The expression has become so iconic that it was added to the Oxford English Dictionary in 2001.

2. The note "Do" in Solfège:

   • In music, "Do" (often spelled "Doh" in some regions) refers to the first note of the solfège scale, which is a system used to teach pitch and sight-singing. This system assigns syllables to the notes of the scale, with the first being "Do" (or "Doh"), followed by "Re," "Mi," "Fa," "Sol," "La," and "Ti."

Please let me know if you're referring to something else, and I can provide more specific information!
