Interval Ear Trainer

Interval Ear Trainer (iET) is an interval ear training app for musicians: helping you recognize intervals faster, more reliably, and more instinctively. ★Build a precise ruler for your ears. For beginners, clearly distinguishing the distance and quality between two notes is essential for understanding melody, tonal context, and harmonic function. iET goes beyond quizzes: it identifies frequently missed intervals, pairs you confuse, and other weak spots, then turns them into focused drills you can start immediately. You can tailor the pitch range, answer mode, and practice focus to your level and needs, then drill specific interval sounds. Especially useful for: • Beginners and independent learners • Learners who struggle to hear melodic leaps or are thrown off by changes in timbre or register • Pianists, guitarists, and other instrumentalists who want their ears to keep up with their fingers • Singers who struggle with pitch or want to sharpen their melodic listening skills • Anyone who wants to build a reliable ear for foundational intervals such as major thirds, minor thirds, perfect fifths, and octaves Intervals give your ears a ruler for pitch distance; tonal awareness gives you a map of where the music is going. iET helps you sharpen that ruler first, laying a solid foundation for melodic dictation, harmonic listening, improvisation, arranging, and performance. ★Key Features • Free Practice Set the question range to suit your level and goals, and choose melodic, harmonic, or mixed interval practice. Beginners can answer by interval number alone to develop a sense of distance, then progress to full interval names and qualities such as major, minor, perfect, augmented, and diminished. • Training Lists Get started with built-in Starter Templates, or create, edit, and categorize your own practice sets. Begin with a small set of intervals, build consistency, then gradually expand the range. The full version supports Training List import and export. Teachers can also create and export goal-specific lists for students to import on their own devices. • Answer Analysis Review your practice history and track accuracy, frequently missed intervals, and pairs you tend to confuse, so you can see how your skills change over time. The full version adds more history ranges and custom filters. • Weakness Drills From your analysis results, start targeted drills for missed or confused intervals with one tap, or add those intervals to a Training List with one tap. • Visual Aids Switch among note names, staff notation, piano keyboard, and guitar fretboard views. The fretboard supports five positions and custom inlay patterns, so the on-screen fretboard more closely resembles your own guitar and makes it easier to connect each interval you hear with fretboard positions and fingering. • Sing-Back and Pitch Guidance Enable the microphone for real-time, on-device pitch guidance during sing-back practice, linking what you hear with what you sing and strengthening pitch memory. • Local-First Practice records stay on your device.
