Enharmonic scale

An enharmonic scale refers to a musical concept where two notes, though written differently, are effectively the same pitch. For example, the note C♯ (C sharp) and D♭ (D flat) are enharmonically equivalent; they sound the same on a piano keyboard but are notated differently depending on the musical context. In the context of scales, an enharmonic scale can relate to the use of these equivalent note names or alterations.
