Musical imitations as their own form of art
Composers often play around by inhabiting an older style of composition. This seems to be particularly true of the modernists of the twentieth century. In part I suspect it's a way of demonstrating beyond question that they know exactly what they're doing, that what they normally write isn't just a bunch of random noise, no matter what you yahoos think.
Revivals as a way of getting into the essence of a style
Revivals often allow an artist an interesting perspective. Looking back, they can see more clearly the quiddity of a style, what makes it what it is, than practitioners at the time possibly could. In addition, there is no idiosyncratic patron, perhaps one who is an enthusiastic amateur performer on the flute or bassoon, breathing down their neck. Sometimes it is an homage in the form of habitation, of getting inside the mind of an admired predecessor. And sometimes it is just fun dance music, more an exercise in creative orchestration than anything else.
Hence works like Prokofiev's First Symphony, "the Classical Symphony", and Tchaikovsky's Fourth Orchestral Suite, "Mozartiana".
Cute and sometimes moving
I actually like a lot of this kind of work, and used to pick it up on used LPs. Much of the lighter side of it comes out in ballet suites based on Baroque composers, such as Thommasini's "The Good-Humored Ladies" (after Scarlatti) and Walton's "The Wise Virgins" (after Bach). and Beecham's "Love in Bath" (after Handel). Very light, but a great pleasure.
Also in the dance vein are a couple of Richard Strauss suites: "Divertimento" and "Dance Suite" (both after Couperin).
More melancholy and moving is a piece by the less-known Alfred Schnittke. of partly Volga German ancestry, who lived during the Soviet period. Suite in the Old Style is lovely. It is not in imitation of anyone in particular, just Baroque in general, and in fact is a reworking of various film work that he did, including for an animated children's film. There are many arrangements, some for chamber orchestra, some for cello and piano, but I favor the violin and piano version at the link. I particularly like the Vadim Guzman performance, but it does not seem to be available on YouTube.
Are there any stylistic revivals that you find particularly interesting?
Mine are mostly Moderns doing Baroque. Are there other combinations I should check out?
