不是生命終點的告白,而是對未來的探索:安涅斯、沙馬尤聯手錄製《舒伯特:鋼琴四手聯彈》

  在鋼琴世界裡,「四手聯彈」始終是個邊緣但是關鍵的類型。它既不是鋼琴獨奏,也不同於雙鋼琴作品,而是兩名演奏者必須在同一台樂器上共享鍵盤與踏板,迫使演奏者放棄對樂器的完整控制權,學習與「另一半」傾聽與協調。這種「一個鍵盤,兩人共奏」的體裁,直到十八世紀後半葉才逐漸定型。一七七七年,英國音樂史學家、作曲家伯尼(Charles Burney)在倫敦出版「為兩名演奏者在同一架鍵盤樂器上而寫的奏鳴曲或二重奏」,讓「四手聯彈」首次成為一種落諸樂譜、可實際練習並演奏的音樂形式,也為後來莫札特與舒伯特把它推向藝術高峰鋪設平路。

  由挪威鋼琴家安涅斯(Leif Ove Andsnes)與法國鋼琴家沙馬尤(Bertrand Chamayou)聯手錄製的《舒伯特:鋼琴四手聯彈》(Schubert: Four Hands),正是一張以表現「兩名鋼琴獨奏家在同一台鋼琴共享聲部與控制權」為出發點的專輯。曲目集中在舒伯特一八二八年完成的鋼琴四手聯彈作品,包括F小調幻想曲,D. 940A小調快板《生命風暴》(Lebensstürme),D. 947E小調賦格,D. 952,以及A大調輪旋曲,D. 951。這是舒伯特生命的最後一年,專輯將把目光鎖定在這個關鍵的創作晚期,引領愛樂者深入探尋舒伯特在生命終點前,充滿張力且細膩的創作心境。

  談到這一年,後人經常為它抹上一層浪漫的色彩,彷彿每一首作品都預感死亡的迫近。然而,安涅斯與沙馬尤都對這種說法不表認同。他們認為舒伯特未必察覺自己已經接近生命終點,因為他在這一年還向奧地利作曲家與理論家塞赫特(Simon Sechter)請益對位法,積極精進自己的創作功力。這個背景,正好幫助我們理解這些作品的創作方向:與其說是情感上為人生做總結,不如說是舒伯特持續思考「音樂還可以怎麼寫」的成果。作品中可以清楚聽到多聲部同時運作,內聲部不再只是陪襯,而是積極參與音樂的推進;他對賦格與對位的興趣,也讓音樂結構變得更細緻而緊密。這些特點都顯示,此時的舒伯特並沒有把創作收斂到內省或簡化,而是持續往更複雜、更成熟的寫作方向前進。
  對長期以獨奏家身分活躍於舞台的鋼琴家而言,四手聯彈並不是獨奏能力的延伸,而是必須重新適應學習的過程。安涅斯形容,每一個人都只掌握一半的鍵盤,必須在極為有限的空間中重新調整自己對音量、觸鍵與時間感的處理。沙馬尤則以弦樂四重奏作比喻:負責低聲部時,右手的位置如同中提琴,必須同時承擔支撐結構與調節色彩的責任;擔任高聲部時,左手不再是習慣中的低音基礎,而是更接近第二小提琴的角色。這種身體角色與聲部配置,迫使鋼琴家跳脫獨奏慣性,用不同的角度思考作品。此外,踏板通常由負責低聲部的演奏者控制,但必須同時顧及兩個聲部,而非單一演奏者的需求。這些都使得四手聯彈成為一種極為親密、也極為脆弱的合奏形式,稍有不慎就會造成演奏上的不協調。

  除了曲目選擇,這張專輯的特點也來自兩位鋼琴家各自帶來的舒伯特經驗。安涅斯長年演出舒伯特的鋼琴奏鳴曲與藝術歌曲,對樂曲的長線推進與聲部間的幽微關係格外敏感。他曾經引用布蘭德爾(Alfred Brendel)對舒伯特音樂「夢遊感」的描述,認為舒伯特的音樂經常給人一種「真相近在咫尺,卻始終觸不可及」的感受。這讓安涅斯處理舒伯特晚期作品時,並不刻意透過戲劇化手段製造效果,而是傾向讓音樂自然展開。

  沙馬尤則不然。舒伯特始終是他無法完全輕易掌握的作曲家。也正因為如此,他在演奏舒伯特的時候,特別強調節制與結構的嚴謹。在他的獨奏經驗裡,舒伯特的音樂要求演奏者同時維持旋律的歌唱性與清晰的整體結構,而這兩者之間往往存在須要協調處理的拉鋸。沙馬尤傾向以穩定的節奏、清楚的聲部層次處理與整體架構的理性掌握,避免旋律情緒過度膨脹或失焦。正是這種理性的處理方式,使他在四手聯彈中,為音樂提供可靠的時間框架與聲部秩序,成為合奏穩定清晰的基礎。

  演奏這套曲目時,兩人的聲部分工是依曲目交換:F小調幻想曲與A大調輪旋曲由安涅斯擔任高聲部;《生命風暴》與E小調賦格則由沙馬尤擔任高音聲部。這種安排並非為了凸顯誰是主導者,而是讓兩位鋼琴家在旋律、內聲部與結構支撐之間輪流轉換角色。而從聆聽的角度來看,這種輪替方式打破高低聲部主從角色的刻板印象,使音樂更接近一場真正的對話。

  兩位鋼琴家的合作並非刻意安排,而是音樂道路上的自然交會。多年前,沙馬尤曾經因為手部問題向比利時鋼琴家提耶日(Jacques de Tiège)求助,而這位鋼琴家也正是安涅斯的老師。後來,安涅斯聽到沙馬尤為Erato錄製的舒伯特鋼琴獨奏專輯,對他的詮釋方式產生共鳴,於是二○一六年在挪威創辦羅森達爾室內樂音樂節(Rosendal Chamber Music Festival)時,邀請沙馬尤共同演出F小調幻想曲D. 940。後來兩人都形容那次合作經驗為「自然且動人」,也成為日後持續合作的起點。

  進入錄音階段後,兩人的合作默契轉化為更具體的工作協調。兩人都提到,四手聯彈的錄音並不是把舞台演出原封不動保留下來,而是一個不斷溝通與調整的過程。聲部如何平衡、踏板該如何運用、乃至於旋律與結構如何取捨,往往需要反覆討論與嘗試,每一處選擇,都必須同時顧及兩人的觀念、技術與其他詮釋考量。也正因如此,更顯得舒伯特的鋼琴四手聯彈作品,本質上更像是一種對話,而非單一情緒的堆疊。至此愛樂者可以明瞭,這張專輯提供一個理解舒伯特晚期創作的觀察視角:在繁複的多聲部交織中,音樂不再只是獨白,而是一場極其細膩、精巧、深刻的對話。裡面未必是舒伯特對終點的感懷,而是對未來的渴求與探索。

In the world of the piano, four-hand playing has always occupied a marginal yet crucial position. It is neither solo piano nor music for two pianos. Instead, two performers must share a single instrument—keyboard and pedals alike—requiring each to relinquish full control and to learn how to listen to, and coordinate with, the other. This form of music-making, often described as “one keyboard, two performers”, did not fully take shape until the latter half of the eighteenth century. In 1777, the English music historian and composer Charles Burney published Four Sonatas or Duets for Two Performers on One Keyboard Instrument, marking the first time four-hand music appeared as a notated, practicable genre. This laid the groundwork for Mozart and Schubert, who would later elevate it to an artistic peak.

Schubert: Four Hands, recorded by the Norwegian pianist Leif Ove Andsnes and the French pianist Bertrand Chamayou, is an album conceived precisely around this idea of “two piano soloists sharing a single instrument and its control”. The programme centres on Schubert’s four-hand works from 1828, the final year of his life: the Fantasia in F minor, D.940; the Allegro in A minor, D.947 (Lebensstürme); the Fugue in E minor, D.952; and the Rondo in A major, D.951. By focusing on this decisive late period, the album invites listeners to explore Schubert’s creative state of mind at the very end of his life—a world of heightened tension and extraordinary refinement.

Posterity has often cast this year in a romantic glow, as if each work were written under the shadow of impending death. Andsnes and Chamayou both resist this view. They argue that Schubert may not have been aware that he was nearing the end, noting that in this very year he sought instruction in counterpoint from the Austrian composer and theorist Simon Sechter—hardly the action of someone resigned to death. This context helps to clarify the direction of these works. Rather than a summing-up of life in emotional terms, they can be understood as the result of Schubert’s continuing exploration of how music might still be written. Multiple voices operate simultaneously; inner parts no longer serve merely as accompaniment but actively drive the music forward. His growing interest in fugue and counterpoint tightens the musical fabric and refines its structure. All of this suggests that Schubert was not withdrawing into introspection or simplification, but pressing on towards greater complexity and maturity.

For pianists long accustomed to the concert platform as soloists, four-hand playing is not simply an extension of solo technique but a process of re-learning. Andsnes describes how each performer controls only half of the keyboard and must recalibrate their approach to dynamics, touch, and timing within extremely limited physical space. Chamayou likens the experience to a string quartet: when playing the lower part, the right hand occupies the middle register, much like a violist, supporting structure while shaping colour; when taking the upper part, the left hand—no longer providing the bass foundation—assumes a role closer to that of a second violin. This redistribution of physical and musical roles forces pianists to abandon solo habits and rethink the music from a different perspective. Pedalling, usually controlled by the player responsible for the lower part, must serve both parts simultaneously rather than a single line. These factors make four-hand playing an intensely intimate and inherently fragile form of ensemble music, where the slightest misjudgement can disrupt the whole.

Beyond repertoire, the album also reflects the distinct Schubert experiences each pianist brings. Andsnes has long been immersed in Schubert’s piano sonatas and songs, developing a keen sensitivity to long-range musical flow and to the subtle interplay between voices. He has often cited Alfred Brendel’s description of the “sleepwalking” quality of Schubert’s music—the sense that truth is always close at hand yet never quite grasped. Consequently, Andsnes avoids overtly dramatic gestures in late Schubert, allowing the music to unfold naturally rather than forcing expressive effects.

Chamayou approaches Schubert differently. For him, Schubert has never been a composer who yields easily, and precisely for that reason he emphasises restraint and structural clarity. His solo experience has taught him that Schubert demands a careful balance between lyrical cantabile and architectural coherence—two impulses often in tension. Chamayou therefore favours steady tempo, clear voicing, and rational control of form, resisting emotional inflation or loss of focus. In the context of four-hand playing, this disciplined approach provides a reliable temporal framework and a clear ordering of voices, forming the stable foundation of the duo’s ensemble.

In this programme, the distribution of parts changes from work to work. Andsnes takes the upper part in the Fantasia in F minor and the Rondo in A major, while Chamayou assumes it in Lebensstürme and the Fugue in E minor. This arrangement is not designed to establish hierarchy, but to allow each pianist to alternate between melodic prominence, inner voices, and structural support. From the listener’s perspective, this rotation dissolves fixed notions of principal and subordinate parts, turning the music into a genuine dialogue.
Their collaboration was not the result of deliberate planning but of a natural convergence of musical paths. Many years ago, Chamayou sought help for a hand problem from the Belgian pianist Jacques de Tiège, who also happened to be Andsnes’s teacher. Later, Andsnes heard Chamayou’s Schubert solo recording for Erato and felt a strong affinity with his approach. When Andsnes founded the Rosendal Chamber Music Festival in Norway in 2016, he invited Chamayou to perform the Fantasia in F minor, D.940. Both pianists later described that experience as “natural and deeply moving”, and it became the starting point of their continued collaboration.

In the recording studio, this musical rapport took the form of detailed practical coordination. Both pianists emphasise that recording four-hand music is not a simple preservation of a live performance, but a process of constant discussion and adjustment. Decisions about balance between parts, pedalling, and the relative priority of melody and structure require repeated experimentation. Each choice must accommodate both players’ musical ideas, technical considerations, and interpretative aims. For this reason, Schubert’s four-hand works emerge not as accumulations of emotion, but as conversations in sound. The album thus offers a way of understanding Schubert’s late style: within intricate polyphonic textures, the music becomes not a monologue, but a subtle, finely wrought, and profoundly human dialogue—less a meditation on endings than a reaching forward towards what might still lie ahead.
