I would say I am a low-professional-level pianist: I have many years of training and graduate degrees, and am capable of making a living at it and have done so in the past. But I never had the degree of aptitude or ability for obsessive focus such that I could have been a major professional performer (recordings, international concert schedule, teaching job at a top music school), so I turned more toward music scholarship, which suits me as a career very well. I still do play some in various personal/professional settings.
