Enharmonic Intervals
Intervals that sound the same but are spelled differently.
Enharmonic Equivalence
Enharmonic intervals share the exact same pitch frequencies, but use different note names based on their musical context (e.g., C# vs Db).
Spelling Matters
The way an interval is spelled helps musicians understand its function and direction within a key. This will be explored in greater depth in other modules.
Summary
Enharmonic spelling is like using homophones in language; context dictates the correct spelling.
