The actual frequency at which an object vibrates at is determined by a variety of factors. Each of these factors will affect either the wavelength or the speed of the object. From
frequency = speed / wavelength
a change of velocity or wavelength will result in a change in the natural frequency. The role of a musician is to control these variables to produce a given frequency from the instrument that is played. Consider as an example a guitar. T

frequency = speed / wavelength
a change of velocity or wavelength will result in a change in the natural frequency. The role of a musician is to control these variables to produce a given frequency from the instrument that is played. Consider as an example a guitar. There are six channels, each having a different linear density (the larger strings are denser on a per meter), a different voltage (which can be controlled by the guitar), and a different length (also controllable by guitarist) . The speed at which they move through the waves of channels depends on the medium properties – in this case, the sealing (pressure) of the chain and the linear density of channels. Variations in these properties would affect the natural frequency of the particular channel. The vibrating part of a particular channel can be shortened by pressing the string against one of the frets on the neck of the guitar. This change in the length of the chain would affect the wavelength of the wave and in turn the natural frequency at which a particular string vibrates. Control of the speed and wavelength in this manner allows a guitarist to control the natural frequency of the vibrating object (a string) and therefore producing musical sounds intended. The same principles can be applied to any string instrument – whether the harp, harpsichord, violin or guitar.
