I have been asked to play in a private Seniors' Residence on a Sunday afternoon, in June. My 60-minute-program will consist of 6 pieces by Gurlitt (from opus 140), 6 pieces by Schumann (from opus 68), one piece by Mendelssohn, to be followed in a second part by various old American songs from around 1900 (ballads, waltzes and comic songs from silent movies), and, possibly, two short "encores".
Of course, I have to learn and 'maintain' this program everyday till the 'big day'. So, I just wondering what fee a professionally-trained pianist can ask for this type of program - which involves preparation and daily practice.
