The online tuner is chromatic and uses your microphone.
Therefore, it allows you to tune any musical instrument : guitar, bass guitar, ukulele, banjo, mandolin, violin, viola, cello, double bass...
It analyzes the sound captured by the microphone then displays the nearest note to this sound and the distance between them.
If only central green bar appears this means that the sound played is perfectly in tune with the displayed note.
If several green bars appear but no yellow bar, then the sound played is still in tune with the displayed note.
However, whenever yellow bars appear, the sound played isn't in tune with the displayed note.
For tuning your instrument, you have to know the name of the note and its octave (example : E2).
To help you, many tunings are listed : guitar, 12 string guitar, bass guitar, 5 string bass guitar, 6 string bass guitar, 4 string banjo, 5 string banjo, mandolin, ukulele, violin, viola, cello, double bass.
Act on your instrument so that the note displayed is the one you want to tune to.
Then continue to act on your instrument so that no yellow bar is displayed.
Select "guitar" tuning in the tuner.
The notes corresponding to each string appear : E2 A2 D3 G3 B3 E4.
Pick low E string (fat string) which must be tuned to the E2 note.
If the note displayed is not E2 but another one lower (respectively higher), tighten (respectively loosen) the string till tuner displays E2.
Once done, continue to adjust the string so that no yellow bar is displayed.
Repeat this process with the other strings.
