Never played piano before required college piano proficiency classes. I would consider myself a beginner piano player.
Took up to a year of piano before college, along with college classes. I can play very simple accompaniments for my students, but need to use recorded accompaniments for anything more difficult.
Took several years of piano before college. I am a confident player and accompany most of my school groups. I may even play in other places such a church, family gatherings, etc.
I am a pianist. I have taken plenty of lessons, and can play about anything I need to support my band.
