I don't gig and have no musical commitments. I just play for enjoyment, or, creatively speaking, because I can't help myself. And there are times when I don't feel like playing piano, either because I'm bored with what I sound like, or just feel like "why bother?". I also play guitar, so sometimes I get involved with that at the expense of the piano. Usually, I gravitate back to the piano, maybe because I've had an idea, or heard something that reminds me of something, or something else. But what really makes me want to sit down at the keys is listening to Bill Evans. Even though I don't play like Bill, and never will, sometimes I just feel like I want to make some of those sounds, the feeling that comes from creating a voice, maybe even a single chord. The goal at that point isn't to try and play like Bill, but to try and capture the essence of how Bill expresses a melody or phrase or combinations of notes over a chord. Once that impetus strikes, I'm good for while, until I get bored with my playing again.
