Jam Session

We mean that the musicians all try to join in together, perhaps agreeing a tune that they know before starting off, perhaps someone playing something that they think others will know. Some of these have individual turns too, either by the discretion of the organizers or because someone starts something that no one knows! This often happens if someone starts singing. These sessions can call for a bit of sensitivity; musicians are seldom all of the same calibre and you may be required to be forgiving of poorer musicians or restrained if you can't play as well or brave if you want to improve your own playing!
