How do you change the pitch of stringed instruments?

Answer 1

You change the pitch of a guitar string by altering the tension. This is done by turning the 'machine head' which is the bit attached to the headstock (top of the guitar) where the strings attach. There should be 6 knobs sticking out. Turning these changes the picth of the string. Don't turn the string up too high or you'll break the neck.

Answer 2

Pitch is a function of string length and string tension. If the tension is increased or decreased by turning the tuning peg, the string's pitch will be raised or lowered. If the string's length is increased or decreased by fingering or the application of a capo, its pitch will be raised or lowered.
To affect the pitch of the guitar as a whole, prior to performance:

1. Use the tuning pegs to select the tuning of each string, and to make fine adjustments. This is usually too awkward to do during a performance, but it has been done
2. Use a capo to raise the pitch of all strings simultaneously, effectively shortening the guitar.

During performance, the pitch of a guitar string can be controlled by several techniques.

1. Fretting the string with the left hand effectively shortens the string and raises the pitch. This is the normal way that notes are made when playing.
2. "bending" the string by pulling it sideways with the left hand increases the tension and raises the pitch . This is typically used for microtonal effects in blues and Rock Music.
3. In Classical Music, the string is stretched with the left hand along the string's axis, resulting in microtonal effects (such as a vibrato)
4. A "tremolo bar" (really a misnomer) is a tool on some electric Guitars that simultaneously changes the tension on all strings during a performance, affecting the pitch.
5. When playing harmonic effects, the selection of the node point on the string will determine the pitch of the harmonic note.
6. Some musicians have been known to apply pressure to the headstock of the guitar, slightly bending the neck, and lowering the pitch for effect.
7. When executing a "pick scrape", the pitch of the noise is controlled by the speed of the pick.

Answer 3

The pitch of stringed instruments can be changed in 2 ways.

1. Change the tension of the string. Tightening it for higher pitch or loosening it for lower.

2. Shortening the length of string allowed to vibrate. This is usually accomplished by depressing the string on a fretboard. Shorter strings make higher pitched sounds.

Answer 4

By placing your finger on the string anywhere on the guitars neck.
There are two main methods for changing the pitch of a string.

Tension - The tension applied to a string will determine its pitch; the tighter, the higher. It is common to use this principle for tuning an instrument (although in rare instances like the dan bau it is used to change pitch when performing).

Length - The shorter a string is, the higher it will be (keeping tension the same). On instruments like the violin and guitar this is done using the fingers of the left hand by pressing on a specific place upon the string.

If you want to keep the tension and length the same, using a thinner string will also raise the pitch, though this is obviously a difficult way to fine-tune pitch.

Answer 5

With the tunning pegs at the head of guitar

the lowest string should be tuned to e

next string a

next string d

next string g

next string b

next string(the highest pitched one) e

Answer 6

By moving the placement of your' fingers up and down the fretboard or by changing the tunning of a string at the tunning machine.

Answer 7

Tighten or loosen strings
