Do you have any performance guidelines?

When I first started composing, I mistakenly thought that everyone would intuitively understand how to perform my music, as it was so clear to me. I quickly learned that was not the case, and over the years, I have included more markings in an effort to share my feelings about the music and its performance. For me, having an expressive performance is paramount, so in a way, the markings are only guidelines. I hope each performer will find the best way to make the music leap off the page. Regarding metronome markings — these are guidelines as well. When I perform my own music, I can rarely stay in one tempo for even one measure.
