German speaking nations give maximum importance to Piano and Violin instrumental music and hence maximum composers are commemed there.
Russian speaking countries give importance to Ballet as most popular art form but still you will find coins on some composers like A P Borodin, A N Scriabi, Hamza Hakimzadi Niyazi etc.
Belgium, most of which is Dutch speaking, favours painting as the art form of choice. Guitar playing Jean "Django" Reinhart is only music composer who ppears to havbe been commemed on a coin unless you include Maurice Maeterlinck, who works have been subject of opera, which is the art form of choice in french speaking part of Belgium ( as it is France).
Belgium is a reluctant issuer of commem coins, unlike its neighbour Luxembourg, which avails all opportunities. Let us see if i succeed in getting a coin issued on 200th birth ann. of Adolphe Sax, the inventor of Saxophone, next year.
Italian speaking areas prefer to go for sculpture, which incidentally happens to be my favourite form of art.
