You can tune your violin using the standard A440 tuning or classical Bach time tuning using the real violin sound. You can also tune your violin using a frequency from 428 hertz to 452 hertz as the A note.
With A440 and harmonic tuning, you can play the single pitches G, D, A and E with a real violin sound. From 428 hertz to 452 hertz tunings you can play the pitches G, D, A and E with a sine wave generator.
The program tells you quickly and precisely with the accuracy of a tenth-semitone step when the violin is in tune.
You can also use the program to tune other instruments such as guitar or ukulele.
