About This Sing-Intervals Trainer
Recognizing an interval is half the skill — producing one is the other half. This free trainer plays a root note and names an interval; your job is to sing the target note that completes it. Real-time pitch detection listens through your microphone and tells you immediately whether to aim higher or lower.
How to use it
Enable your microphone, listen to the root, and sing the requested interval above it. The live feedback guides you onto the note; hold it steady to confirm. Replay the root whenever you need to re-anchor your ear, and use a comfortable octave for your voice.
Level progression
Begin with small, singable intervals such as major seconds and minor thirds, then work outward toward fourths, fifths, sixths, and the octave. Because you must produce the pitch, not just name it, progress here transfers directly to sight singing and improvisation.
FAQ: Can I hum instead of singing?
Yes — humming, singing on a vowel, or even whistling all work, as long as the microphone can pick up a clear, steady pitch. Everything is analyzed locally in your browser; nothing is recorded or uploaded.
