How good is your musical ear? Find out – and train it a little better every day. Sonaris turns ear training into a game: short training sessions, real piano sound, and a score that shows how your ear develops. Whether you're learning an instrument, singing in a choir, producing music, or simply curious – this is where you train the skill that music is really about: listening closely. FOUR CHALLENGES, ONE GOAL • Order tones by pitch – Hear several tones and arrange them from high to low. Three difficulty levels, from beginner to pro level with quarter tones. • Interval training – Two tones play: how many semitones apart are they? The supreme discipline of ear training. • Absolute pitch – A tone plays, you find the key. On the piano keyboard or directly on the staff. • Find the error – A chord is shown, but the pianist plays one note wrong. Can you hear which one? THE HEARING SCORE Your progress in one number: the Hearing Score (0–1000) measures your skill across all challenges – not how much you play, but how well you hear. Rise from Beginner through Music Ear and Golden Ear to Absolute Pitch, and compare with friends and family. TRAIN SMART • Short sessions of 5 rounds – perfect for in between • Tiered hints when you get stuck • Per-challenge statistics show your progress over time • Real piano sound instead of sterile sine tones KIDS MODE A dedicated child-friendly mode with big symbols and simple comparison tasks – with parental gate and no personalized ads. 10 LANGUAGES English, German, French, Spanish, Italian, Portuguese, Chinese, Japanese, Korean, and Arabic.
