Notzart

Note trainer with mic โ€” play a note, Notzart recognizes it instantly. Notzart turns your phone into a music-reading coach. A note appears on the staff; you play it on your real instrument; the microphone listens, the algorithm compares the pitch, and you get a green flash for a correct answer or a gentle red one for a miss. No typing, no buttons โ€” just play. Designed for beginners and pre-conservatory students, equally useful for adults brushing up on score-reading. SIX INSTRUMENTS Piano, Guitar (6-string, 19 frets), Bass Guitar (4-string, E1 to G4), Flute (C4 to C7), Violin and Cello. Each gets its own optimised microphone preset and a dedicated screen โ€” keyboard, fretboard or intonation light. REAL MUSIC NOTATION Treble, bass, alto and baritone clefs. Whole, half, quarter, eighth, 16th and 32nd notes with proper note heads, beamed eighths and sharps/flats drawn next to the notes. Bar lines, time signatures, dots, ties, fermatas โ€” the staff looks like the real thing because it is. SONGS TRAINER โ€” 35 BUILT-IN MELODIES From Twinkle Twinkle and Mary Had a Little Lamb to Greensleeves, Vincent (Starry Night), Auld Lang Syne, Hava Nagila, Brahms Lullaby and Minuet in C โ€” six different keys (C, G, D, F major; A, D, E minor) so you practice every accidental that matters in early sight-reading. Each song is broken into 8 progressive stages: right-hand fragments, full right hand, left hand fragments, full left hand, right at tempo, left at tempo, both hands manual, both hands at tempo. The staff scrolls glass-smooth under a fixed playhead, the beat clock waits for your first note before starting, and you can jump bar by bar at any moment. CHROMATIC TUNER A separate Tuner tab with a cents meter, animated needle, green/yellow/red zones, and open-string references for guitar, bass, violin and cello. Tune your instrument before you practice โ€” no app-switching. FOUR LANGUAGES, THREE NOTE SYSTEMS English, Russian, Italian, Spanish. Pick Do Re Mi or C D E or Russian solfege for note names โ€” independent of UI language. OCTAVE-ACCURATE The pitch detector returns the correct octave too โ€” C4 and C5 are never confused. Choose which octaves to practice in Settings and narrow the range to your current level. METRONOME 2/4, 3/4, 4/4 and 6/8 time signatures. BPM 30 to 240, visual beat dots, audible tick that won't fight your instrument. STATS AND HISTORY Top 8 best practice sessions are saved automatically with date, accuracy percentage, streak and counts of correct and wrong answers. All data stays on your device. PRIVACY No account. No analytics. No ads. Microphone audio is processed live in memory and never recorded, stored or transmitted. Kuka Soft notzart.kuka-soft.com mail@kuka-soft.com
