Hint: Jal tarang is an instrument which produces music due to percussion or gentle taps on cups which contain water of different levels. One of the cups are tapped using beaters or sticks and the other using fingers. These different levels of water produce beautiful and soothing sounds.
Jal Tarang roughly translates as water waves or waves in water. This is an ancient Indian instrument which is still in use. It works on the motion of sounds that are created or modified when water in the cup is disturbed. When the bowl filled with the water is tapped, there are vibrations produced. These vibrations travel through water and the surrounding like air for instance to create the soothing sounds. This sound is similar to the Feng Shui wind chimes.
Here, the water in the cup produces a low pitch or a low frequency sound, when struck. As the water in the cup is increased, the frequency or the pitch of the sound increases. This variation in sounds is used to produce music.
So, the correct answer is “Option D”.
The Jal Tarang has evolved from the ancient Gamelan and the gong which was made up of copper and various other alloys, when struck gently with a bamboo stick would produce soothing music.
Here, the striking of the surface causes vibration similar to tabalas and drums. Whereas other instruments used strings which cause vibration, like veena and guitars. The sangeet saar, the musical treat using jal tarang uses 22 cups filled with water and 15 porcelain or bronze cups to produce music.
