The Korg VPT-1 is a vocal pitch training tool that displays your singing pitch in real time on a clear LCD screen. Designed for vocalists, choir members, and music students, it helps develop pitch accuracy by providing immediate visual feedback as you sing. A built-in mic captures your voice, and a reference tone function lets you hear target pitches. Training Modes The display shows your sung note name and octave along with a meter indicating sharp or flat deviation. Practice with the reference tone to match specific pitches, or sing freely while monitoring accuracy. The compact size makes it easy to use during vocal warmups and practice sessions.
