When a quiet section is maintained for a certain period of time, the Stable (locked) status is displayed → You can even visually experience the process of your ears stabilizing. Directly check the variation in vibrato pitch with the pitch trajectory. ▣ An instrument tuner covering strings, guitar, and ukulele. Dedicated tuning modes are provided for each instrument, including guitar, ukulele, violin, viola, cello, and double bass. Designed to visually display the target pitch/position for each string, even beginners can easily gauge which string to raise and lower by how much. The K-Tuner is not a tuner that simply "roughly matches pitch," but rather a practice tool that actually improves your skills. ▣ A Smart Metronome that Develops a Sense of Rhythm The metronome, along with pitch practice, provides an all-in-one music practice experience.
