Acoustic attenuation in water is frequency-squared dependent, namely =. Acoustic attenuation in many metals and crystalline materials is frequency-independent, namely =. [10] In contrast, it is widely noted that the of viscoelastic materials is between 0 and 2.
Eight-string classical guitars are generally tuned with two extra basses ([BD]EADGBE) that vary in pitch depending on the piece being played. Another common variation is to add an extra bass and treble string. The extra treble is almost always tuned to A, [citation needed] while the added bass string usually falls on A,B, or C.
The steel-string acoustic guitar typically has a scale slightly shorter than the classical instrument, the most common scales ranging between short scale (24 inches (610 mm)) and long scale (25.5 inches (650 mm)). Small travel guitars and guitars specifically designed for children can have even shorter scales.
The predecessor of today's six-string classical guitar was the five-string baroque guitar tuned as the five high strings of a six-string guitar with the A raised one octave. High C – E-A-d-g-c' Standard tuning with the B tuned a half step higher to C to emulate a six-string bass guitar, minus the low B.
Both of these systems, and the vast majority of music in general, have scales that repeat on the interval of every octave, which is defined as frequency ratio of 2:1. In other words, every time the frequency is doubled, the given scale repeats. Below are Ogg Vorbis files demonstrating the difference between just intonation and equal temperament ...
The classical guitar, also known as Spanish guitar, [1] is a member of the guitar family used in classical music and other styles. An acoustic wooden string instrument with strings made of gut or nylon , it is a precursor of the modern steel-string acoustic and electric guitars , both of which use metal strings .
