Vibrato Trainer is the only metronome built around a new understanding of how vibrato actually works. Based on original research by Michael Van Bebber, Vibrato Trainer reveals that vibrato is not a fixed speed — it is a rhythmic subdivision of the musical pulse. As tempo changes, the correct vibrato subdivision changes predictably across six distinct tempo zones. This app maps that relationship for you automatically. Set your tempo, and Vibrato Trainer shows you exactly which subdivision your vibrato should follow — and lets you hear and feel it in real time. Features: - Tempo-synced vibrato metronome from 50–400 BPM - Automatic vibrato subdivision mapping across 6 tempo zones - Tap tempo - Time signatures: 4/4 · 12/8, 3/4 · 9/8, and 2/4 · 6/8 - Separate volume controls for beat click, vibrato click, and pitch tone - Piano keyboard for pitch reference (C3–C6) - Four waveforms: sawtooth, square, triangle, sine - Visual dot animation synced to vibrato rhythm For singers, string players, wind players, brass players, and jazz musicians.
