Enharmonic equivalent is a musical term, meaning the use of different note names for the same sound pitch. For example, on the piano keyboard the black key between C and D can be named C# or Db.
The figure below shows an example of an enharmonic equivalent on the guitar fretboard. The first string on the sixth fret is surrounded by A (fifth fret) and B (seventh fret). Therefore, we can have either an A# or a Bb on the sixth fret.
Enharmonic equivalents can also be found on the ukulele fretboard! Check out the example below. As you can see, the first string on the sixth fret is surrounded by D (fifth fret) and E (seventh fret). Therefore, we can have D# as well as Eb on sixth fret.
Taking into consideration the images above, here is a list of examples of enharmonic equivalents:
- C# / Db
- D# / Eb
- F# / Gb
- G# / Ab
- A# / Bb
