Enharmonic Equivalent

Two tones that sound the same but are named differently

In equal temperament (one of the modern musical tunings), enharmonic equivalent refers to "two notes with the same pitch", but they each have "two different names".

For example, in piano, the black key between C and D can be called C♯ or D♭. Although C♯ and D♭ have the same pitch, different names have different functions depending on the harmony and chord progressions.
