I practiced 6-7 times (for 30-45 minutes) in 10 days so that I would be ready to play the prelude and processional/recessional for a graduation last Saturday. For the prelude, I chose 4 songs that I used to play very well so they only needed some practice and polish. The only song that I had to learn was Pomp & Circumstance and, although marches are not my forte, executed it well.
