I've been writing some solo bass stuff for a while now ([Invalid or Expired Link Removed] shameless plug!) and my problem lies not with harmony, or writing melodies or even whacky techniques but with my timing. I feel like I am focusing so much on playing the write notes that I speed up and slow down in ways that aren't exactly...nice. Any pointers? (there are tempo changes that aren't condusive to metronomes in some of them)
