Watch the sitar being played in the video, let's test your prediction based
on the video.

If the zither is pressed in two different positions supertied in figures (a) and (b)
which one do you think is louder?

Sitar as well as guitar is a musical instrument that uses strings as a source of sound. The sitar can
produce di erent notes by pressing certain parts of the string as it is plucked. The tone produced with
the simplest pattern is called the fundamental tone, then successively the wave pattern that is
formed produces the 1st overtone, the 2nd overtone, the 3rd overtone and so on. Read carefully the
description of the notes on the strings.
TONE WAVE EQUATIONS
A string with length L forms ⁄
λ So:
L = ⁄ λ then λ = 2LM Then the
fundamental frequency is,
