Full description
"I panic when I see chords..." "I can read Treble Clef, but Bass Clef is hard..." Solve these problems with vivo, a sight-reading training app that supports Chords—a rare feature in the market! Perfect for piano students and anyone wanting to read sheet music fluently. Improve your sight-reading skills in just 1 minute a day. 🎹 vivo Features 1. Supports Chord Reading!

Gamified "Note Calculation" "Quarter Note + Eighth Note = ?" A unique calculation mode where you add up note values (lengths). Understanding note durations correctly helps you build a solid foundation for Rhythm Sense, essential for performance. 3. Comprehensive Music Theory Covers essential musical knowledge beyond just reading notes. • Key: Identify the key from the key signature. • Closely Related Keys: Understand the circle of fifths and key relationships. • Intervals: Identify degrees between two notes (e.g., Major 3rd, Perfect 5th). • Time Signature: Basics of rhythm and meter. 4. Customize to Your Level • Clefs: Treble Clef, Bass Clef • Difficulty: Easy to Hard • Accidentals: Sharp, Flat on/off Suitable for beginners to intermediate learners wanting to solidify their foundation. 5. Track Your Growth Check your daily learning history with the Calendar (Records) function. Seeing your consistency helps you realize "I can read better!" and keeps you motivated.
