a. Method of Experiment.

From the fixed pitch of B as the lowest range on the Naga cup-violin, the musical notes of Do, Re and Mi (B, C sharp and D)were played on all the four present instruments of different tribes, Marok kongki, Nraiibu, Gongkih lahha and one fitted with strings of the western violin. The experiment was to measure the intensity of sound, degree of volume or the loud-ness amongst the instruments. As the particular Naga cup violin has a limitation of low volume and less possible pitches, which makes it un-reliable for modern songs or to fit in a particular song. All the pitch were recorded DO, RE and MI from the master pitch off B, with the help of Audacity audio recording application, after which the frequencies of each instrument were analyzed with the audio spectrum analyzer
