Weekly rehearsals are going well, and the band is sounding tighter. I make sure we use a metronome when we practice so if anyone sways from the beat, they and feel it and get back on. It seems like a lot of the people in the class are inexperienced at playing with other musicians, and as a result the groups are lacking confidence as I saw when they performed their tunes for the class. I have noticed that the groups are tending to sound more together when rehearsing by themselves, another indication of stage-fright/pressure/embarrassment. Although, after mondays in-class performance I feel that most people still weren't happy with their performances, and that they will be giving themselves a kick in the ass :)
