A general term for musical instruments with keyboards, such as pianos and organs. Since there are various sound-generating mechanisms operated by the keys, it is a one-sided category in musical instrument classification. Keyboard instruments have relatively free sound-generating mechanisms, which makes it possible for large instruments such as organs to be played by one person, but they also have the disadvantage of making it difficult for the player to be closely involved with the instrument. Most instruments produce sound indirectly, and the player has no control over the tuning or sound change from onset to silence. However, there are some instruments, such as the accordion, whose performance is greatly influenced by actions other than key operation. On the other hand, because the relationship between sounds is easy to grasp visually, they play a major role in education and theoretical research. Other advantages include the ability to play multiple notes and chords in any combination, and the ability to play instruments with similar playing devices (such as the clavichord and harpsichord).

ピアノやオルガンなど、鍵盤をもつ楽器の総称。鍵によって動かされる発音機構はさまざまであるため、楽器分類上の項目としては一面的である。鍵盤楽器は、発音機構を比較的自由に設計できるため、オルガンのように規模の大きな楽器を1人で演奏することも可能になる半面、楽器に対する身体のかかわりが密になりにくいという欠点ももつ。発音が間接的であるうえに、音律や、発音から消音までの音の変化が演奏者の自由にならない楽器がほとんどである。ただしアコーディオンのように、鍵操作以外の動作に演奏が大きく左右される楽器もある。一方、音の関係が視覚的にとらえやすいため、教育や理論研究への役割が大きい。また、自由な組合せの重音、和音を鳴らせることや、類似の演奏装置の楽器(クラビコード、チェンバロなど)を演奏できることも利点になっている。 [前川陽郁] ©Shogakukan"> 代表的鍵盤楽器の発音機構 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 |
