One of the most fundamental elements of a freelance collaborative pianist's career is their pricing model. Should you charge for every hour worked or per project?

When playing for events such as student recitals, the wrong choice may mean either being taken advantage of or being perceived as overcharging. Mathias Meyer on Freelance Switch has just written an article on Hourly vs. Fixed Pricing for freelance professionals that should be required reading for all that tread this route.
As usual, comments are welcome.
