〈論文〉連弾や２台ピアノから得られる効果的なピアノの上達―ソロとデュオ双方の取り組みで見える相乗効果―

[Abstract] Performing on a piano can give us satisfaction and joy when we can play well. But the practice that is needed to reach that point consists mainly of continuous, steady tasks which also require a lot of time and patience. I have experienced many cases in which students have gained resistance or hatred toward playing the piano before they have overcome those tasks. But even during those periods, I have had many students who showed progress after performing a duo/four-handed performance at an annual piano recital once a year. When students perform a dual/four-hand performance, often they will have improved their skills by adding synergy to their general practice. While a classical solo piano piece requires slow and steady effort in practice, a duo/fourhanded piece is often less difficult. Also, it requires less burden for each person to practice. But because it will be performed by two people, those melodies can turn into a significant piece, and they are even easy, students can experience a rich harmony of piano music, as well as the joy of performing with one another. As a result, such a process can lead students to feel that playing the piano is fun and encourage them to continue playing the piano. It will not only motivate them to practice more in general, but also the solo piece that they are practicing will also be favorably affected by it. And it will effectively improve their overall musical skills. Based on those experiences, and by looking back on my past 34 years of teaching piano, I will talk about the importance of duo/four-handed performances. [要約] ピアノを演奏するにあたり、弾けるようになると楽しく満足感を得られるが、スムーズに弾けるようになるまでの「練習」は、地道な作業で、かなりの時間と忍耐が必要となる。そして、その地道な「練習」を乗り越える前に、ピアノに対する抵抗感や嫌悪感を抱くケースを数多く経験してきた。そうした中、年に１度開催する「ピアノ発表会」で、ソロ曲と連弾もしくは2 台ピアノ曲の両方を演奏披露する事で相乗効果が生まれ、上達に結び付いていると思われる生徒を今まで数多く指導し育ててきた。地道な練習が多いクラシック曲を一人で演奏するソロ曲に比べ、連弾や２台ピアノは、一人あたりの難易度、練習量の負担が少ないにも関わらず、二人で一緒に弾く事で難易度が高くスケールの大きな曲へ変化し、ハーモニーの豊かさや二人で一緒に作り上げる喜びと満足感が得られる。その結果“ピアノを弾くことが楽しい” “ピアノがまた弾きたい”という意識を持ち、練習のモチベーションが上がり、同時に練習をしているソロ曲にも影響を与え、効果的にピアノの上達に結びつく。その経験を基に、ピアノを指導してきた３４年間を振り返りながら「連弾」「２台ピアノ」を教材に取り入れることの重要性を論じる。
