Every note lives in relation to another — and the distance between them is where the magic happens. Some gaps whisper, some shout, some pull you home. Explore how intervals stretch across the stave and how they ring in your ear, from tight half-steps to soaring octaves.
Intervals are the heartbeat of music. They’re the tiny sparks and wide-open skies between notes. Stack them close and you get tension, pull them apart and you get release. Scales are nothing but intervals in a row, chords are intervals stacked into towers, and melodies are intervals set in motion. Learn to feel these spaces, and you start to hear music not as notes on a page but as living shapes and colors.
Intervals are music’s invisible geometry. On the page they’re lines and spaces apart; in sound they’re flavors — sweet, tense, open, or resolved. Learn to see their shapes on the stave, hear their colors by ear, and connect the two into one instinct. Practice spotting the spacing and playing them on the keyboard.
Open Notation Trainer →Intervals are the leaps and steps that give music its shape. A tiny half-step can make your skin crawl, while a wide leap feels like flying. Spin through seconds, thirds, fifths, and octaves — and learn how each jump changes the mood of a melody. Hear them, sing them, and type the right answer. Train your ear to recognize intervals instantly.
Open Ear Trainer →Intervals aren’t just theory — they’re the shortcuts your brain uses to recognize, sing, and play music with confidence. Once you know their shapes and sounds, every score becomes easier to read and every melody easier to catch. The best part? You don’t need hours of practice — just a few minutes a day with the trainers above. Jump in, listen, play, and let intervals become second nature. Your ear — and your hands — will thank you.
