A blog post from last week at On An Overgrown Path conceptualises classical music as a venn diagram with four elements: enlightenment, entertainment, education and engagement. The illustration plots a variety of figures from classical music at different places in this diagram, giving a neatly concise idea of their primary contributions to the genre.
Interestingly, Andre Previn is the only face to appear in the intersection of all four circles, which presents him as a more rounded musician than Beethoven. (Arguably, from this analytical perspective, he is – but you can just imagine the amused and self-deprecating murmur he would emit if accused of this.)
