How good is your musical ear? Find out โ 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 โ this is where you train the skill that music is really about: listening closely. FOUR CHALLENGES, ONE GOAL โข Order tones by pitch โ Hear several tones and arrange them from high to low. Three difficulty levels, from beginner to pro level with quarter tones. โข Interval training โ Two tones play: how many semitones apart are they? The supreme discipline of ear training. โข Absolute pitch โ A tone plays, you find the key. On the piano keyboard or directly on the staff. โข Find the error โ 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 (0โ1000) measures your skill across all challenges โ 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 โข Short sessions of 5 rounds โ perfect for in between โข Tiered hints when you get stuck โข Per-challenge statistics show your progress over time โข Real piano sound instead of sterile sine tones KIDS MODE A dedicated child-friendly mode with big symbols and simple comparison tasks โ with parental gate and no personalized ads. 10 LANGUAGES English, German, French, Spanish, Italian, Portuguese, Chinese, Japanese, Korean, and Arabic.
