What is the same melodic idea starting on a different pitch?

A melodic idea that starts on a different pitch is often referred to as a "transposed melody." This involves taking the original melody and shifting all its notes up or down by a consistent interval while maintaining the same rhythm and contour. For instance, if the original melody starts on C and is transposed to start on D, every note would be raised by a whole step. This technique allows for variations while preserving the essence of the original melody.
