About This Interval Ear Trainer
An interval is the distance between two pitches, and hearing intervals accurately is the foundation of transcription, improvisation, and sight singing. This free trainer plays melodic intervals — ascending or descending — as well as harmonic intervals, where both notes sound at the same time, and asks you to name what you heard.
How to use it
Press Listen (replay as often as you need), then choose the interval name, from minor second up to the octave. You get instant feedback with the correct answer, and an optional tonal anchor keeps your ear grounded in a key. In the settings you can switch note naming (A–G, fixed Do, or movable Do), change the instrument sound, and adjust the pitch range to match your comfort zone.
Level progression
You start with a small set of strongly contrasted intervals. Consistent correct answers unlock new intervals step by step, while repeated mistakes temporarily narrow the set so you can rebuild accuracy before the difficulty rises again.
FAQ: How long until I recognize intervals reliably?
Most learners hear clear progress within two to four weeks of ten-minute daily sessions. Linking each interval to a reference melody you already know — a perfect fourth with the wedding march, for example — speeds things up considerably.
