01
Listen
A piano, guitar, or sine tone plays the interval, scale, or chord.
Now on iPhone
Hear the space between notes.
Intervals is ear training for people who play. Daily lessons, drills for the ones you mix up, and a microphone that checks if you can sing it back.
02
Name it
Pick the answer. Mixed-up drill comes back to the ones you miss.
03
Sing it
Match the pitch with your voice. The app listens on the microphone.
