加拿大數(shù)學家發(fā)明新樂器:形似吉他 聲如洪鐘 |
|
新華社北京６月９日專電據(jù)美國《科學新聞》周刊網(wǎng)站日前報道，幾位加拿大數(shù)學家聯(lián)合發(fā)明了一種形似吉他，聲若洪鐘的新樂器。 據(jù)報道，新樂器名為“曲他”（ｔｒｉｔａｒｅ），外形酷似吉他，比吉他多兩個琴頸，六根弦呈Ｙ形。設計者是加拿大蒙克頓大學的數(shù)學家塞繆爾·高德特和克勞德·高蒂爾。 高德特介紹說，與普通吉他相似，曲他每根弦的上半部分也是從調(diào)音弦軸一直延伸至琴頸，但是下面很不同：曲他琴弦在一個沒有與琴體固定的節(jié)點開始分岔，分岔后的兩個弦段通向兩個新增的無品琴頸。 高德特說，普通琴弦發(fā)出帶有泛音的基本音頻，而曲他的音頻是基本音頻的整數(shù)倍。此外，曲他不僅能發(fā)出泛音，還能發(fā)出如同鐘和鑼等打擊樂器發(fā)出的和弦外音。根據(jù)不同的演奏方式，曲他的琴音中會包含或多或少的和弦外音。 美國物理學家和實驗樂器制造者本杰明·Ｗ·維戈達認為，目前利用計算機進行的音樂實驗非常之多，曲他也許會是最后一批完全依靠物理特性、沒有加入任何計算機因素的新樂器之一。 |
