The Chinese word 柴可夫斯基 is formed by phonetically transliterating the Russian surname Tchaikovsky, using characters whose pronunciations approximate the original sounds: 柴 (chái) for "Tchai", 可 (kě) for "ke", 夫 (fū) for "fu", 斯 (sī) for "s", and 基 (jī) for "ky", creating a sequential sound-based representation.
