2. tuning.

IMPORTANT. Please note this tuner uses a vibration sensor, not a microphone. Therefore it is necessary for the clip to remain in contact with a vibrating surface. Singing, for example, will not activate the tuner; this is normal.

Before tuning your instrument you have to prepare the job, making sure you know what end result you want to obtain.

for example: for the guitar the standard tunings of the open strings are e a D G B e ( from low (thickest string) to high (thinnest string), “open tuning” meaning no fingers on the fretboard.

for the bass the tuning is e a D G from low to high for the ukulele the most common tuning is G C e a for the violin the tuning is GDae once you are ready to start the tuning:

1. Please clip the tuner onto a proper position of the instrument

(the more it vibrates the better it is), and turn the display for easy observation.

2. switch on the tuner.

3. select the kind of instrument you wish to tune.

4. if you have never used a tuner before, go to point 5, if you are familiar with tuners then you have probably discovered all the functions as they are automatic.

5. for stringed instruments it is always prudent to start from a situation where the strings are definitely too loose.

Choose a string and gradually increase the pitch until you find the note in the display that you want to obtain. then the needle will indicate if the pitch is still too low when it is on the left side or too high when it is on the right side. if the needle is in the middle the whole screen will turn green. this means the string is in tune. repeat for all strings. seeing as the neck will adapt to the force of the strings, it may be possible that you need to tune all the strings a couple of times. also keep in mind that strings tend to stretch, especially when they are new.

if you don’t feel confident with this method, then it might be a good idea to switch to chromatic mode. this way you can follow the increasing pitch with successive notes so that you understand the direction in which you are moving.

for instruments other than stringed ones you should use the chromatic mode and refer to the manual of the instrument or look on the web to find a way to tune the instrument.

the tuning procedure is the same. You produce a note. read on the tuner what note it is and decide if you must tune it higher or lower. again, when the needle is in the middle and the screen lights up green, the tone corresponds exactly to the note on the display.
