Tuning the guitar
There are many ways of tuning the guitar, yet, the easiest and most suitable one for the beginner is 'Unison' which its rules are shown belows.
1. When tighter strings or higher sound are required, then, pegs will be turned by the thumb and the left fingertip in such a way inclining toward player's body and turns it outward direction if a lower sound is demand.
2. The pitch of the 5th string is supposed to be the same as the LA sound or the 34th sound in a way the DO sound of piano is used as the first sound.
3. Tuning the 5th string to the LA or A sound which this could be compared to standard sound as a tuning fork or an accurately tuned piano.
4. Tuning the 6th string to the 5th open string or the two notes either by pressing the string at the V bar (Roman numbers are used for an international record of the guitar).
5. Then, pressing the left finger on the 5th string of the V case, this sound is the same pitch for tuning the 4th open string.
6. Pressing the 4th string of the V case and tuned to the 3rd open string.
7. Pressing the 3rd string of the IV case and tuned to the 2nd open string.
8. Pressing the 2nd string of the V case and tuned to the first open string.

The 6th open string sound will be the octave and the 4th string sound when placing the left finger on the 4th open string and 5th open string at the II bar. While pressing the 3rd string of the II bar by the left finger will give you the sound of the octave and the 3rd string.
The 4th open string causes the sound of the octave and the 2nd string of the III case as the 3rd open string will give the sound of the octave and the first string of the III case. The 3rd open string will give the sound of the octave and the first string of the III case.
The 2nd open string gives the sound of the 8 two notes and the 5th string of the II case. The first open string brings the sound of the octave and the 4th string of the II case and also 2 octaves with the 6th open string.
These also could be checked as follows.
1. The 6th open string and the 5th string of the VII case give an octave.
2. The 5th open string gives the sound of the octave and the 4th string of the VII case.
3. The 4th open string gives the sound of the octave and the 3rd string of the VII case.
4. The 3rd open string gives the sound of the octave and the 2nd string of the VIII case.
5. The 2nd open string and the first string of the seventh case will be an octave.
6. The second open string and the sixth string of the second case will also be an octave.
7. The second open string and the fifth string of the second case give an octave.
8. And finally, the first open string and the sixth open will be two octaves.
