The strings must be vibrating slowly but widely to create a low note.
The law of vibrating strings is the vibrational mode of a string that is stretched. The wavelength is twice the length of the string.
The three main sources of musical sound are vibrating strings, air columns, and membranes. Vibrating strings, found in instruments like guitars and violins, produce sound through their oscillation. Air columns, utilized in wind instruments such as flutes and trumpets, generate sound by the movement of air within the instrument. Membranes, like those in drums, create sound by vibrating when struck or played.
