there is a big difference between a wedding pro key player and a pro player that playes in the high level .
Some wedding pro players i know are of the extreme highest level...
Its not where they play that determines their skill level..
Overhere its not easy to make a living in music, which makes some people choose for a combination of music(wedding player) and a different job like for example running a music shop or doing some studio work... the gigs are what brings in the majorrity of their money ..
While i know so called professional keyboardists that play in bands and the like that could barely play when their band stated out...while some wedding players studied music at the university..
No... its noabout where they play that determines their quallity, its allways about their training and how they play...
