VISAYAS ARUDING The frame is held firmly against the performer's parted teeth or lips (depending on the type), using the jaw and mouth as a resonator, greatly increasing the volume of the instrument. The teeth must be parted sufficiently for the reed to vibrate freely, and the fleshy parts of the mouth should not come into with the reed to prevent damping of the vibrations. The note or tone thus produced is constant in pitch, though by changing the shape of his or her mouth, and the amount of air contained in it (and in some traditions closing the glottis), the performer can cause different overtones to sound and thus create melodies. The volume of the note (tone) can be varied by breathing in and out.
BUKTOT In the Southeast Asian archipelago island known as the Philippines, a buktot instrument is defined as a visayan stringed instrument. Each buktot has four strings, and each one creates a sweet and traditional sound which really captures the essence of the island and its people. The buktot is one of many classic Filipino instruments, including the lantoy. If you're curious about traditional musical instruments, you may be fascinated by the way they tend to vary from nation to nation and continent to continent.
