Guitar Tuning is one of the techniques for pitch adjustment for each string of the guitar which makes use to accomplish a prescribed arrangement of notes form the open string. There are various methods which being used for tuning guitar which are as follows,
It is mostly popular on a 6-string guitar. The note arrangement that compromises of the following:
1st string having note e' tune to frequency 329.6 Hz
2nd string having note b to frequency 246.92 Hz
3rd string having note g 196.0 Hz
4th string having note d 146.8 Hz
5th string having note of 110Hz
6th the lowest having note E 82.4 Hz.
Some notes that need to be keep in mind while tuning the Guitar are:
It is an equal tempered instrument.
Guitar is one of the transporting instruments. The pitch sounds one octave, lower than it is notated. The pitches which are referred then referred standard pitch a'= 440 Hz. Letter names table reflect pitch in Helmholtz pitch notation. In some parts of Germany, the B natural symbol is transformed in to letter H.
There are different pattern which are denoted as E-A-d-g-b-e'. Standard tuning is evolved to give a good cooperation between simple fingering for many chords. It has capability to play common scales with minimal left hand movement. The division of the first e' and second b strings. The notes of the chromatic scale which has to be played with each of the four fingers of the left hand which control one of the first four frets. It gives a symmetry and intelligibility to fingering patterns. Separate the second b and third g-string is by four-semitone interval. It breaks the fingering pattern of the chromatic scale and in this way, it makes symmetry. It make easy to used chords and scales. It gives diversity in fingering possibilities.
Open string note arrangement compromises are called as alternative tuning that is very different from standard tuning. Most of the Guitarist used to make this note arrangement that makes helps to exploit unique chord voicing and sonorities that result form them. Many chord shapes are related with standard tuning. This chord becomes a lot easier to play the guitar this way. Alternative stringing need different tuning but also it need to be re-stringing with the string that is better suited for open string note.
Rock Music tunings make the power chords easier to play and or to make the sound "heavier". Dropped D method is generally used by metal and rock bands. It gets also used by folk musicians. It can be played with single finger while putting on the lowest three strings. It gets used highly in classical guitar music. Some guitarists use to use a capo on the second fret. While using this they continue playing power chords without any darker sound by the D tuning.
Dropped C tuning is same as dropped D. lets look at drop C tuning be C-A-d-g-b-e'. Technically it is being called as Dropped D tuned down one whole step" is normally called as Dropped C.
