Question: Found the following article online, use it to answer the question: What is the name of the best known non-vocal piece by Massenet?  Massenet was a fluent and skilful orchestrator, and willingly provided ballet episodes for his operas, incidental music for plays, and a one-act stand-alone ballet for Vienna (Le carillon, 1892). Macdonald remarks that Massenet's orchestral style resembled that of Delibes, "with its graceful movement and bewitching colour", which was highly suited to classical French ballet. The Méditation for solo violin and orchestra, from Thaïs, is possibly the best known non-vocal piece by Massenet, and appears on many recordings. Another popular stand-alone orchestral piece from the operas is Le dernier sommeil de la Vierge from La Vierge, which has featured on numerous discs since the middle of the 20th century.A Parisian critic, after seeing La grand' tante, declared that Massenet was a symphonist rather than a theatre composer. At the time of the British premiere of Manon in 1885, the critic in The Manchester Guardian, reviewing the work enthusiastically, nevertheless echoed his French confrère's view that the composer was really a symphonist, whose music was at its best when purely orchestral.  Massenet took a wholly opposite view of his talents. He was temperamentally unsuited to writing symphonically: the constraints of sonata form bored him. He wrote, in the early 1870s, "What I have to say, musically, I have to say rapidly, forcefully, concisely; my discourse is tight and nervous, and if I wanted to express myself otherwise I would not be myself." His efforts in the concertante field made little mark, but his orchestral suites, colourful and picturesque according to Grove, have survived on the fringes of the repertoire.  Other works for orchestra are a symphonic poem, Visions (1891), an Ouverture de Concert (1863) and Ouverture de Phèdre (1873). After early attempts at chamber music as a student, he wrote little more in the genre. Most of his early chamber pieces are now lost; three pieces for cello and piano survive.

The Méditation
