Melodies and chords are made of intervals, so hearing them speeds up everything else.
Recognize leaps in a tune and play them back without hunting for notes.
Knowing how a 4th or 6th should sound makes pitching new melodies easier.
An interval is the distance between two pitches, counted in semitones. A minor 3rd spans three semitones, a perfect 5th spans seven and an octave spans twelve. Ascending and descending intervals of the same size sound different, so practice both directions.
Harmonic intervals, where both notes sound at once, test your ear for consonance and dissonance. Perfect 5ths and octaves blend smoothly, while 2nds and 7ths rub against each other. Reference songs give each interval a memorable hook to recall during the quiz.
Unison, 4th, 5th and octave sound open and stable.
2nds, 3rds, 6ths and 7ths come in major and minor sizes, one semitone apart.
Six semitones, exactly half an octave, with a famously tense sound.
Begin with the beginner preset of major 2nd, major 3rd, perfect 4th, perfect 5th and octave. Add minor intervals once you score above 80 percent.
Linking an interval to the opening of a song you know gives you an instant memory cue until the sound becomes familiar on its own.
Yes. The lower note is chosen at random across about an octave and a half, so you learn the interval rather than a fixed pitch.
Both notes are played at the same time instead of one after the other.
