How to tune your musical instrument to a particular frequency?

The easiest way is to adjust the frequency produced by any instrument to the right pitch.

For example, in Guitar, the E string vibrates at the frequency of 329.63Hz. If you pluck the first string, the software shows 329.6Hz and show the E4 note.
Looking at the physics of a vibrating string, the lowest frequency produced by any instrument is called the fundamental frequency.  The fundamental frequency is also known as the first harmonic of the instrument.  329.63 Hz is the fundamental frequency of the E string.
