About

Vibrato Mastery

Read full description

Vibrato Mastery is a real-time vibrato analysis app designed primarily for violin, viola, cello, and double bass players, from a functional basic vibrato all the way up to an already great vibrato. It can also be used with other sustained-pitch instruments through the neutral profile, but it is not designed for voice. See what your vibrato is actually doing as you play, with clear feedback on speed and amplitude: • Speed, measured in Hertz (Hz) • Amplitude, measured in cents (±) Built from first principles, Vibrato Mastery focuses on the essential elements behind controlled and expressive vibrato: rhythm, speed, amplitude, consistency, control, and refinement. To get the most out of the app, read the in-app Guide before practicing. It explains how to understand the feedback and use the app correctly. KEY FEATURES: REAL-TIME VIBRATO ANALYSIS Get instant visual feedback while you play. See your vibrato speed and amplitude clearly, without relying only on feel or guesswork. OPTIONAL DIGITAL BOOKS The built-in Store includes optional Vibrato Mastery digital PDF books for violin, viola, cello, and double bass. Each book provides structured exercises based on the same method, for players who already have a functional basic vibrato, all the way up to an already great vibrato, and want a deeper path of refinement. CLEAR VISUAL FEEDBACK The interface is simple and easy to read at a glance, so you can stay focused on your instrument while still understanding your vibrato. Stop wondering whether your vibrato is improving. Know it. Download Vibrato Mastery today and begin your true path to greatness.
