Full description

How long does it take you to identify an interval on the staff? Or read a note? Intervalos is your ear-training and sight-reading coach: build speed and accuracy with progressive visual exercises, made for musicians who want to read sheet music with more fluency and confidence. TWO TRAINING MODES • Intervals — identify the distance between two notes on the staff. Master all 13 musical intervals, from unison to the octave. • Notes — read individual notes on the staff at speed. From anchor notes to full fluency across two octaves. SUPPORTED CLEFS Practice in your instrument's clef: • Treble clef — violin, flute, right-hand piano • Bass clef — double bass, tuba, left-hand piano • C clef — viola, trombone, French horn LEVEL-BASED PROGRESSION 5 interval levels and 5 note levels, unlocked one at a time: • Tutorial with theory explanations and real music notation • Mini-quiz at the end to confirm what you learned • Adaptive algorithm: the intervals you miss most show up more often • Placement test for players who already have some background PRACTICE MODES • Timed: 1, 2, or 5 minutes — track how you improve over time • Free: no time limit, go at your own pace • Custom: choose exactly which intervals or notes to practice • Difficulty presets: Beginner, Intermediate, and Advanced STATS AND TRACKING • Correct answers, mistakes, and average response time • Best session saved by mode and duration • Improvement trend across sessions WHO IS IT FOR? • Students of solfège, music theory, or sight-reading • Instrumentalists who read sheet music: piano, violin, guitar, flute, viola… • Conservatory and music school students • Teachers looking for practical exercises for their classes Start with 1 minute a day. The difference in your sight-reading will follow.

What's new
