About Ascending Intervals
An interval is the distance between two pitches. Ascending intervals measure the distance going up from a starting note. Understanding intervals is fundamental to music theory—they're the building blocks of scales, chords, and melodies. This tool focuses on calculating the correct note name (with proper enharmonic spelling) for any interval above a given pitch.
Why Enharmonic Spelling Matters
A major third above C is E, not Fb—even though they sound the same on a piano. Correct spelling matters because it reflects the interval's function in harmony. A diminished fourth (C to Fb) and a major third (C to E) are different intervals with different musical meanings, even if they're the same number of half steps.
How to Practice
Start by memorizing the intervals from C, then work through other starting notes. Think in terms of scale degrees: a major third is always the third note of a major scale. For altered intervals (augmented, diminished), modify the natural interval by a half step. Use the 60-second challenge to build speed.
Common Challenges
Double sharps and double flats often trip up students. Remember: an augmented fifth above G# is Dx (D double-sharp), not E. The letter name must reflect the interval number (fifths span five letter names).
