Ear Trainer
Practise identifying intervals by ear. Pick which intervals to drill, choose ascending / descending / harmonic, and the tool plays them for you.
Direction
Intervals to drill
5 intervals selected. Start with 4-6 to keep the quiz tractable.

Score: 0/0
Pick which intervals you want to practise above, then press Start quiz. The tool plays two notes — your job is to identify the interval between them.
About interval ear training
Identifying intervals by ear — telling a perfect 5th from a major 6th, an octave from a minor 7th — is the foundational skill behind transcribing melodies, sight-singing, jazz improvisation and basic music theory ear quizzes. Most music schools drill it in the first year of theory class. The trick is consistent repetition with focused subsets — practise three or four intervals at a time until they're rock-solid before adding more.
This tool plays a root note then a target note (or both at once for harmonic intervals) and asks you to identify the interval between them. Pick which intervals to include, pick the direction, and start the quiz. Score keeping is local — nothing is logged, the tally resets when you reload.
How to drill intervals
- 01
Pick a starter set
Start with major 3rd, perfect 4th, perfect 5th, major 6th and octave — the consonant intervals. Add the dissonant ones once you have those down.
- 02
Pick a direction
Ascending is the easiest place to start. Descending and harmonic are harder — work up to them.
- 03
Hit start, listen, click
Listen carefully. Click the interval you think it was. Use the replay button if you need it. Keep going until the percentage feels honest.

Ear trainer FAQ
What's a good starter subset?
Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Octave — the consonant intervals. Tritone and the seconds are the hardest, save them for once the consonants feel automatic.
Why triangle wave instead of piano?
Triangle is harmonically simple but not as harsh as sine. We may add a sampled-piano timbre in a future version. The interval relationship is what you're training, not the timbre.
How is harmonic different from ascending?
Ascending plays the two notes one after the other. Harmonic plays them at the same time. Harmonic is harder because the overtones interact and the brain doesn't get the time-spaced reference.
Are progress / streaks saved?
No — score is in-memory only and resets on reload. Keeps the tool simple.
