It is no understatement to state that Claire Booth is a national singing treasure. She would be too gracious to admit this, but the British soprano has played a leading role in classical music on these shores, particularly in league with composer and conductor Oliver Knussen as a leading exponent of new compositions.

Yet Booth’s pioneering spirit extends to music of the classical canon, and after Knussen’s sad death in 2018 her work has continued apace. In 2024 she has included a special emphasis on the music of Arnold Schoenberg, 150 years on from the composer’s birth. His music remains a challenge today – but as Booth revealed in an enjoyably candid chat, it is a challenge well worth accepting for the performer and ultimately the listener.

Before we discuss Booth’s new Pierrot Portraits album on Onyx Classics, where she is joined by Ensemble 360 to put Schoenberg’s melodrama Pierrot Lunaire in the context of composers inspired by the Pierrot, I ask her if she can remember her first encounter with Schoenberg’s music. It turns out to be a milestone she will never forget. “The first time I did Pierrot Lunaire, which was the first piece of Schoenberg that I did, was with Pierre Boulez at the Lucerne Festival. I was a young artist on the inaugural Festival Academy. The first year that they did that was just the Ensemble Intercontemporain and Pierre Boulez. Every instrumentalist had one student, so there was basically a student ensemble, the Ensemble Intercontemporain, Pierre Boulez and Hilary Summers, who was effectively the singing consultant. I was the student singer, so Pierre Boulez basically taught me Pierrot Lunaire! I sort of went, bowed at his feet and said, “Sprechtgesang – how do you do it?”, thinking this is the master of 20^th century composition, I’ll get this incredible insight – and he must have been about 70, I suppose, and he just looked at me and said, “You sing a bit, you speak a bit. That’s it.” And actually, he’s so right – because you just learn it like any other piece of music, and you do sing a bit and speak a bit! How you do that is up to you. Like a lot of very, very good musicians, they’re very keen to leave it up to the performer. He wasn’t a micromanager,  and when you’re working with really good people they assume you’re as good as them – I mean, the nice ones do. So he just let me get on with it, and those were the parameters.”

Does the straightforward approach remove a temptation to micromanage Pierrot Lunaire itself? “That’s interesting, because you definitely need to put a lot of time in, and by that, you might think, “Gosh, I’m micromanaging this”. But I can think of any Mozart aria that actually, if you pull it apart, you are micromanaging how you are working. There is a certain sense of micromanagement, but there’s quite a negative connotation with that phrase. With Schoenberg’s music people often get stuck in the realm of thinking very carefully and complexly, but ultimately we do that with all repertoire. After that, we free ourselves up and employ our musicality and our professionalism. Once you get to that stage with Pierrot, then it does feel very innate and characterful, you just have to have done the groundwork.”

Booth has worked with one of Pierrot’s legendary interpreters. “I remember Jane Manning told me, in the way that only Jane could, that she had given the most accurate rendition of the piece ever. She’s absolutely right that there is no excuse not to be accurate pitch-wise, but if you listen to someone like Erwin Schrott do Don Giovanni, when he’s singing the recitatives, he’s not caring about the individual notes – but there’s no way he doesn’t know the notes. He’s inhabiting it completely, and it’s such a wonderful way of listening to the freedom of it. You don’t want to get bogged down in the micromanagement of accuracy. You have to be accurate, but then you get to the next level.”

Schoenberg’s detail of colour in the score reaches descriptive heights with the voice and ensemble, colours that present themselves afresh with each listen. “Absolutely. Obviously there were other vocal pieces before Pierrot Lunaire that employed instruments, but I think Schoenberg really did break up the rule book in how he uses the instrumentalists and voice as one. You’ve got five instrumentalists playing eight instruments, and the singer playing three characters and the narrator in a myriad of different emotional states. The palette is so deft that if the performer understands the text in us, it’s a complete gift. The orchestration is so brilliantly witty, clever, charming and poignant – you know, there are echoes of Bach, Mozart, and elegiac and even aggressive qualities to it. Like all the best music there are no extraneous notes, and his decision to play the note in a certain way is just consummate to me. When people come to this new as an audience member, you might be thinking, “What have I let myself in for?” Within five minutes, though, you are in this sound world, and audiences delight in the sheer virtuosity of the world. As a performer you just have to dive right in, and if you really believe in what is written, it’s just mind blowing!”

Booth has also been recording Schoenberg’s early songs with pianist Christopher Glynn, in a compelling Expressionist Music album released earlier this year on Orchid Classics. It reveals the remarkable breadth to their compositional style. “When you listen to pop music you have the Coldplay sound, the U2 sound, and it’s their thing. But one of the reviews of the Expressionist Music disc said it sounds a bit like Mahler or Brahms. Well, what’s wrong with that? These were people in the musical, historical pedigree that he loved and revered. Why wouldn’t his sound world sound like that? I think one reviewer was almost disappointed that it didn’t all sound like Schoenberg. And you’re like, “What is Schoenberg? Is it a kind of construct that we’ve decided is difficult, atonal?” I think an audience’s appreciation of tonality and atonality now is different than it would have been 40 years ago. We’ve all listened to a lot more music, we don’t hear the jarring qualities that atonality maybe heralded within us. My granny might still think it sounds a little bit risque, but, I think we’re much more open to his world anyway.”

She adds some context. “It’s so important, I think, for everyone to recognize that Schoenberg was a product of his time. He didn’t just parachute in with a pistol aiming to blow a hole in everything. He was absolutely continuing as he felt the tradition, but in the way that the expressionist movement, was going he was continuing a movement by forward motion, taking things on a step. You’ve got folk songs, cabaret songs, love songs – he clearly was a man fascinated by a lot of different aspects of life, you know? He had enormous depth and breadth, and that comes across in his vocal music, in terms of his poetry choices. It also comes through in knowing the man – he was friends with Kandinsky and a tennis partner with Gershwin. The guy was a hoot!”

Booth has been working with the Arnold Schoenberg Center in Vienna – a fascinating resource and museum dedicated to the composer, where it is possible to witness a full scale mock-up of Schonberg’s Hollywood apartment. “I’ve been in touch with them over the last year”, she says, “and we’re going to sing there in December and stay in the apartment. We’re really delighted to have that sort of immersion. Even when you go on the website, with the amount of archival material, you can really geek out on it! I think it’s a shame that he’s been so synonymous with all that is difficult and complex about music when there are composers that have come since Schoenberg that have been far more impenetrable. He’s maintained this aura of unapproachability, which you see in the reticence of festivals and promoters to put on his music, even in this 150^th anniversary year, which I just don’t think is justified. So it’s wonderful to get opportunities to be reminded of kind of the breadth of his interests, and how he was a complete part of the kind of wider artistic movement in the 20^th century. He’s such a towering figure!”

Booth has explored a vast amount of new music in her performing career to date. Is there the same thrill of discovering new music as there was with Schoenberg? A prime example is Helen Grime’s Folk, a setting of verse by Zoe Gilbert for soprano and orchestra which she is preparing for performance as we talk. “I think that’s what’s so great about music. I am so on the back foot – in my first lesson at college, I heard this piece of music, and I lent to the next person and said, “This is the theme music to Trading Places!” And she said, “No, it’s the Overture to The Marriage of Figaro!” I know so little about music that I am still discovering so much now – the joy of discovering new music that’s in the canon, together with new music that’s being written now.” If what your question is leading to is the same kind of craft in new music as in Schoenberg then Helen (above) is a wonderful affirmation of that.

Booth elaborates on Grime’s qualities. She’s such a craftswoman, and such a great orchestrator. Not for nothing was Oliver Knussen such a big champion of her in her early days, and that’s one of the reasons we got to know each other. It feels special to be kind of continuing Ollie’s work with the composers he loved and rated, because he was such a meaningful figure to me. I wouldn’t want to speak too broadly about compositional trends in general. I think I’m very fortunate that I get to sing an awful lot of music by people that I particularly love. It’s easier to believe in music that you have an immediate connection to, and I’m lucky to have that. As a singer I’ve still got so much to learn, repertoire wise, and I’m still so curious in that.”

She cites her exploration of the songs of Mussorgsky, in league with her regular pianist Christopher Glynn. “I’d heard a couple of songs, but what an absolute deep dive. You wouldn’t think of him as a song composer! We know Songs And Dances of Death, but, that’s a group of five – and he wrote 60-70 songs! There are some absolute beauties in there, and no extraneous notes. His brilliant use of pace and orchestration – with only the piano – and the wonderful opportunities for female protagonists in his songs, which doesn’t come through so clearly in his operas. As a curious artist, that’s just brilliant. Five years ago I didn’t know any of that, and now I’m a bit of a guru. I think my love of music has maintained my curiosity for the repertoire that’s already out there, and hopefully that’s a way of marrying the two.”

Booth is struck by Mussorgsky’s originality. “When you listen to this writing, you think it’s Mahler or Wolf, and this guy was writing these songs in the 1840s-1850s. He really was ahead of his time. Ollie always did the Stokowski orchestration of Pictures at an Exhibition, with lots of bells! I think purists would say it’s less sophisticated than the Ravel, but there’s an earthiness and a gravitas to it, a sort of ridiculous element which he doesn’t shy away from. The piece is such a smorgasbord, and that’s the word I’ve tried to use with a lot of these retrospectives, and with Schoenberg too. It’s wonderful to be able to advocate for a composer’s breadth, because I think people have one or two pieces by somebody that they like, and that’s great, but that can lead to other things.”

With that in mind, the Pierrot Lunaire album places Schoenberg’s work in the context of a number of different and fascinating responses to the central character. “When you look at versions of Pierrot Lunaire, it’s always intriguing as to what people put it with. Usually it’s with another Second Viennese School composer, and I definitely didn’t want that. It did seem the figure of Pierrot himself is such a magnet for creatives. Schoenberg wasn’t even the only one to set the Hartleben translation.”

“Joseph Marx went in a completely different musical direction to Schoenberg. Kowalski, another Jewish composer of the early 20th century, was actually a lawyer who advocated for Schoenberg when he was having a problem with one of his publishers. He’s done 12 settings of those heart labor poems, but they’re not the same as the ones Schoenberg did. So even with Pierrot Lunaire, we think of it as this seminal work, and it’s wonderful to see how other people have set it. It’s nice to give people a taste of what other composers thought – and even with the Korngold aria, it is this beautifully elegiac piece and so haunting. It’s the ability of the Pierrot character to be so permeable. It’s called Portraits for a reason I suppose, we wanted to present as many different angles as possible.”

We move on to the demands Schoenberg makes on the voice itself. With such a wide range of dynamics and pitches, does the voice need special preparation? “I’ve always done quite a lot of different repertoire concurrently, and I do remember a performance of Pierrot Lunaire where I performed some Handel arias two days later, and I definitely suffered. I remember thinking I would have to schedule these things a bit better. As I’ve gone on in my career, without blowing my own trumpet, I find increasingly that it doesn’t seem to cost any more than singing anything else. I mean, I did some Mozart concert arias in Prague recently, 20 minutes of singing, and I was bloody knackered! If you can get past the complexity of the score and be quite a seasoned interpreter, there is a freedom that comes with knowing something incredibly well, which then allows you to give just the right amount. I’m doing various ‘Pierrots’ this season, and some of them will be next door to singing Debussy, Marx, these other vocal styles – and obviously you need to be ready for both, otherwise you’re short changing the audience.”

Talk turns again to the much-loved Oliver Knussen. What sort of legacy has he left with Claire, and more widely, with British music? “Happily, I’m part of a large family of people who spent time with Ollie and who he was a massive influence on. When I think about Ollie, and his music making, I think of incredible standards and incredible kindness – which extended to nurturing, sponsorship and facilitating of others’ work. He always put his own compositions second, and he really wanted to facilitate others music. He got to know Harrison Birtwistle, reasonably late in his life, but part of that was because I think he felt really second best to Harry, and he was a bit embarrassed. I heard him say he felt his music wasn’t well crafted enough.”

Humility was one of Knussen’s standout qualities. “He was incredibly modest. I was the recipient of so much of his listening, and I suppose the legacy is that I would like to achieve those same exacting standards in my work, the absolute knowledge about and love of the music, and musicality of a properly high standard. As a professional creative, it matters to me, and it mattered to him hugely. The commission with Helen Grime and also Zoe Martlew, this year, who was also an incredibly close friend of Ollie’s, means a lot. When I am involved I do try to remember kind of that Ollie was so generous in his time to advocate for others work. I like to think that he’d be pretty chuffed that I was working with Helen and Zoe in this way. I think he’ll be having a chuckle when Helen’s piece comes to life!”

She goes into more detail. “Ollie worked with quite a small number of musicians over and over, and the rehearsal process was very positive and open and facilitory. I’ve worked with plenty of eminent musicians where the room is not necessarily positive and quite dictatorial and exacting, and now my job is to deliver when somebody wants to be exacting. I really appreciated Ollie’s understanding that if you have booked the right people, they’re going to be good. Treating people with respect and confidence begets that, and having a positive vibe in the room might sound like an obvious thing, but it’s amazing how often that doesn’t happen. In today’s world there’s a lot of talk about this stuff, but I wouldn’t say that people have nailed how to do it. With Ollie, with his potentially intimidating presence, both physically and musically, he was always incredibly respectful and facilitating off of the artists that he worked with. So I hope that if I could generate half of the vibe that he did, I think I’m going the right direction.”
