WebOn classical guitars, the size change is complicated by a change in density: the low density nylon strings get thicker from the E to B to G; then the higher density wire-wound nylon strings get thicker from D to A to E. The frequency can also be changed by changing the tension in the string using the tuning pegs: tighter gives higher pitch.

One key distinction between these terms is that pitch is relative (a matter of common agreement among musicians), while frequency is absolute (a precise, unambiguous measurement). Both describe how often air-pressure levels, or changes in the air's molecular density, repeat.

WebMar 24, 2024 · In layman's terms: bigger, heavier things generally have a lower resonant frequency, and smaller, lighter things generally have a higher resonant frequency. Roughly speaking, to humans this generally means bigger/heavier things sound lower pitched, and smaller/lighter things sound higher pitched. http://hyperphysics.phy-astr.gsu.edu/hbase/Waves/string.html

WebThe reason sound travels faster through water than through air is because water is so much less compressible (stiffer) than air that it more than compensates for the increase in density. Helium and air are both gases with very similar compressibility so the much lower density of helium causes sound waves to propagate about 2.7 times faster ... WebDensity is how much mass is present in a given unit of volume. Things that are more dense generally are thicker, more solid objects that do not allow as much for individual particle vibration....
