All strings are numbered, so for example the string closest to the player of a twelve-string guitar is always string twelve, and never "string six secondary" or similar constructions. In the context of instruments that possess at least one multi-string course , a single string normally played on its own may also be called a course .
In most musical instruments, the tone-generating component (a string or resonant column of air) vibrates at many frequencies simultaneously: a fundamental frequency that is usually perceived as the pitch of the note, and harmonics or overtones that are multiples of the fundamental frequency and whose wavelengths therefore divide the tone-generating region into simple fractional segments (1/2 ...
Tuning is given for a typical single-keyboard, 5-octave instrument, for the main choir of strings. Only lowest and highest octaves are shown; intervening notes are tuned chromatically. Often tuning is in some musical temperament other than 12-tone equal temperament (common on modern pianos).
String gauge refers to the thickness and diameter of a guitar string, which influences the overall sound and pitch of the guitar depending on the guitar string used. [17] Some alternative tunings are difficult or even impossible to achieve with conventional guitars due to the sets of guitar strings, which have gauges optimized for standard tuning.
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
One end is pierced for the string; the other is squared off to fit in a tuning lever socket. The middle section, which would pass through the wood, is tapered. A variety of methods are used to tune different stringed instruments. Most change the pitch produced when the string is played by adjusting the tension of the strings.
New standard tuning (NST) is an alternative tuning for the guitar that approximates all-fifths tuning.The guitar's strings are assigned the notes C2-G2-D3-A3-E4-G4 (from lowest to highest); the five lowest open strings are each tuned to an interval of a perfect fifth {(C,G),(G,D),(D,A),(A,E)}; the two highest strings are a minor third apart (E,G).
A rotary switch is a switch operated by rotation. These are often chosen when more than 2 positions are needed, such as a three-speed fan or a CB radio with multiple frequencies of reception or "channels". A rotary switch consists of a spindle or "rotor" that has a contact arm or "spoke" which projects from its surface like a cam.
