It is a type of idiophone. It is simply a long, cylindrical metal rod bent into an equilateral triangle, one corner of which is hung from a string and struck with a beater. It produces a high, clear sound, but since there is a slit in one corner of the triangle, it does not have a clear pitch. As an orchestral instrument, it can produce a loud sound by striking the base hard, or a tremolo by moving the beater back and forth inside the corner of the triangle. It is also an instrument that can produce a variety of other tones depending on the performer's ingenuity. A representative piece that makes effective use of this is Liszt's Piano Concerto No. 1 (premiered in 1852, commonly known as the "Triangle Concerto"). [Takanori Fujita] Each side is 15cm.

体鳴楽器の一つ。細長い円筒形の金属棒を正三角形に曲げただけのもので、その一角を紐(ひも)でつるし、打棒(ビーター)で打ち鳴らす。高くて透明な音を発するが、正三角形の一角に切れ目が入っており、明確なピッチをもたない。オーケストラの楽器としては、底辺部を強くたたいて大きな音を出したり、三角形の角の内側で打棒を往復させてトレモロを奏したりする。そのほかにも演奏者のくふうによって、さまざまな音色を創出することができる楽器である。なお、これを効果的に用いた代表的な曲に、リストのピアノ協奏曲第1番(1852初演。通称「トライアングル協奏曲」)がある。 [藤田隆則] 一辺15cm。下は打棒(ビーター)©ヤマハ"> トライアングル 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
