A music session support method which enables each of players in a music session which is performed via a network to immediately recognize whether or not the other players are in the state of being able to participate in the session. A session support apparatus 10 transmits sets of status information indicative of whether or not each of players is in a state of being able to participate in a session, and player identification information which identifies the players, to each of session terminals 20. Each of the session terminals 20 which have received the sets of status information and player identification information causes a touch display 24 thereof to display the status information for each of the players. The session support apparatus 10 acquires a set of status transition information indicating that a player of at least one of the session terminals 20 in which the detecting device has detected the performance preparatory operation has gone into the state of being able to participate in a session, and player identification information for a session terminal 20, from the session terminal 20. The session support apparatus 10 transmits the acquired set of status transition information and player identification information to the session terminals 20. Each of the session terminals 20 updates contents displayed on the touch display 24 thereof, based upon the status transition information and player identification information transmitted from the session support apparatus 10.
