This Clip-on Violin Tuner makes it super easy to tune your violin strings.

The digital display shows the note you're currently tuned to, and the handy meter shows how sharp/ flat the note is, allowing adjustments to be made quickly and easily, making this very suitable for beginners.

Of course, it can be used for any instrument, and we've also had success clipping this onto a music stand to use for scale and intonation exercises.
