Composer: (n) a person who writes music, especially as a professional occupation
In the classical field they refer to them as “the Masters.”
These are the folks who wrote symphonies, operas and other various styles of composition, which have endured to the present day.
Please understand, in their time, many of them received no attention, zero appreciation and often suffered criticism and poverty.
It would seem that their greatest accomplishment was that they died. Once they died, a sentimental streak went down the backbone of all the critics, and they began to view their music from a less cynical position.
So now we consider them geniuses–and we take the composers of our day and ostracize them, cheat them out of opportunity and often make them live in poverty (just so they can die quickly and have their music appreciated).
It is a bizarre system which seems determined to continue because it receives great funding.
