cdecde

cdecde is a six-character string composed of the letters c, d, and e, arranged as c d e c d e. It is formed by repeating the three-letter sequence "cde" twice. There is no widely recognized definition for "cdecde" as a standalone term; its meaning depends entirely on context.

In music notation, letters such as C, D, and E can denote pitch classes. Interpreting the lowercase string as pitch names yields C-D-E-C-D-E, a simple melodic fragment that repeats the same three notes. In programming and data processing, "cdecde" can serve as a minimal, predictable input string for testing pattern recognition, parsing, or string handling routines, due to its regular repetition.

Variants of this pattern include any six-character string formed by doubling a three-character block, for example "abcabc" or "xyzxyz". The string "cdecde" is notable for using alphabetically consecutive letters in its three-letter base block.
