The Three Major Parts Of A Triangle
Punctuating most operatic concertos is a high note, a climactic “ting” so to speak. This high note is usually made by striking a triangle. The triangle is a percussion instrument made of a steel rod that is bent into the shape of either an isosceles or equilateral triangle. One of the corners of the triangle is gapped to allow the instrument to vibrate to make that distinct sound. The following are the major parts of a triangle.
1) The triangle's body
The triangle's body is made of a single rod of steel bent into a triangular shape. The brilliance of the tone is dependent on the contents of the steel and thus the purer is the steel the more brilliant is the tone. In the olden times, the gap between one of the corners had designs on them but now the equilateral (all sides equal in length) triangle is much more popularly used. The key difference is the size of the triangle and the measurement of the gap determines the tonal quality of the instrument. With a bigger gap, there is greater space allowed for the vibration of the instrument.
2) The wire or gut
The wire or gut is the means by which the triangle is suspended when held by the player. This piece of rope allows for the vibration of the triangle to be unimpeded. Usually made of twine or plastic to avoid the metal scraping on metal, this wire or gut suspends the triangle in mid air to allow the full dynamic of the vibration to be unimpeded. Oftentimes, the player puts the triangle on a hook with a stand and either strikes the outside part of the rod or strikes all three inner rods of the triangle. This allows for more flexibility for the player to strike the instrument.
3) The beater or wand
The beater or sometimes called the wand is also a steel rod, sometimes with a wrap of leather or rubber but none in the modern triangles. This is held by the player with the option to strike the triangle on any side, either on the outside or the inside. By striking all three sides from the inside, the triangle's vibrations resonate much more clearly and repeatedly. Usually, this is a warning call for all who would hear it.
The triangle is used in modern rock bands and in the more formal full orchestra. The brilliant tone punctuates the musical piece with its high playful notes. The triangle, though a percussion instrument, not only can be used to set the beat but also highlight the changes in harmonies and melodies.
The three parts of the triangle, the body, the gut and the beater, working together under the masterful hand of the player, serves to form part of the musical composition being played. The note would signify high emotion or stern warning when played for alarm. Thus the triangle is a versatile instrument which is easy to learn and with great value for those musical pieces.
