What if a person has just started playing a musical instrument; is it okay to join a jam session?
Of course! If they don’t know the tune, they can just play quietly on the outside of the jam. A more experienced musician might try to catch their eye to see if they would like to “take a break or a solo” on the tune. If the newer person is not comfortable, a subtle shake of the head “no” and everyone will understand that they are still learning.
