How much of lounge pianists playing is from repertoire, and how much is improvised?

I'm unsure as to an arrival of correctly calculated percentage in discovery of how much improv is used during Pianistic lounge performances. A Pianist’s standard and familiar repitoire is the foundatiom for their hours-long accompaniment to a gathering.

Typically performed by myself is lighter fare from a sizeable Classical repitoire, with this repitoire generally not allowing improvisation unless a free form Cardenza is placed within the work, demarked “a piacere”, (or “at your pleasure”).

Improvisation may be of substantial use when a request is asked of me, with my counter intent being to offer the musical suitor a longer, more in-depth rendition of the song they've so desired.

How do I write a character’s physical description without it feeling unnatural and clunky? I’m able to describe their hair and body relatively easily because my writing puts emphasis on small movements and fidgeting, but I can’t describe faces.

Light Jazz and compositions of my personal construction do offer measures in which I may perform at my will. Improv has never been of notice to surrounding guests as they generally know not the proper entails of any work I sound into their ears.

Upon my musical duties having ceased for the evening, I may hold an impressive sum of money in my hands, which is a true honor.

Whether performing at Dinner parties, Engagement celebrations or a company’s Holiday gathering, the pleasantries of providing low-key background aires is mine.
