Classical guitar technique finger) and plucking the string with the ring finger or thumb of the right hand. In the left hand, each finger is responsible for exactly one fret. For each hand-position of four frets, the left hand is stationary while its fingers move. Consequently, three hand-positions (of frets 1-4, 5-8, and 9-12) cover the 12-fret octave of each string. In common with other classical stringed instruments, classical guitar playing and notation use formal positions of the left hand. The 'nth position' means that the hand is positioned with the first finger over the nth fret. There are many exercises that can
String vibration or, perhaps more easily, by adjusting the machine heads, to obtain the same, or a multiple, of the AC frequency to achieve the same effect. For example, in the case of a guitar, the 6th (lowest pitched) string pressed to the third fret gives a G at 97.999 Hz. A slight adjustment can alter it to 100 Hz, exactly one octave above the alternating current frequency in Europe and most countries in Africa and Asia, 50 Hz. In most countries of the Americas—where the AC frequency is 60 Hz—altering A# on the fifth string, first fret from 116.54 Hz to
