Iv'e been playing for 16 years and I cursed myself by never practicing with a metronone. Im in a improv.jazz/rock band(some players would shoot me for putting jazz and rock together) and I always screw up the timing!!! I have no problem with rythem but soloing I have a big problem playing in time.
So I just wanted to post some advice---ALWAYS pracice playing in time and when You do start to play with other people--listen to the music as a whole not just your-self!!
