Press Play interval when you are ready.

Score: 0 / 0

What you are naming

Each question picks one interval from the list and a random starting note in a one-octave range around middle C. The first tone is the root. The second tone is the root plus that number of semitones. Frequencies use the session A4, which starts at 440 Hz.

This is a short drill, not a graded exam and not a claim about concert hearing. If the tones overlap your metronome, stop the session click first.

Worked examples

C to G is a perfect fifth, seven semitones. After you hear the pair, do you sing the second tone before you press a button?

A minor second is one semitone. It is the closest pair in the set. Can you tell it from a major second?

A perfect octave is twelve semitones. The two tones share a letter name. Does that make the answer easier than P4?

Questions

Why is the augmented fourth missing from the list?

The first drill keeps seven common names. The interval calculator can still name A4 / d5 if you type two pitches there.

Does the score leave the browser?

No. Refreshing the page returns the score to 0 / 0.

Ascending only?

Yes. The second tone is always higher than the first in this version.
