Does anyone do this? I guess this would be more applicable for faster songs that have a lot of intricacies. Maybe you have a song that you normall play at 200 Bpm. and just to see where you need improvement as a band, go a head and try playing through the song at 140 or something. I've never done this, sounds like it would bee a good idea to make sure that everyone is hitting everything together, or if not. Everyone is not hitting the way they should. If ya can't play it slow you can't play it fast. Could you use this as a way of pointing out other peoples mistakes without them getting mad, or causing too much trouble? It would make sure everyone knows whether or not they are playing certain parts with the correct timing. Thoughts?
