Illustration is made, with reference to a ease study of airport landing congestion in the New York area, of how numerical solutions may be easily obtained for the transient behavior of nonstationary waiting lines characterized by Poisson arrivals, constant holding time, and service in order of arrival. In the case study only the mean arrival rate vanes as a given function of time, but the methods used as easily provide for variation also of servicing rate and of number of servers. Exact numerical values are sought and obtained only at intervals of the servicing tune While these times were short in the case study, so that little information is sacrficed, the method may be adapted to yield more frequent values in the case of long servicing times. Subject to this restriction, the entire probability distribution of the queue is calculated as the main numerical routine, from which the distribution of waiting time is directly obtained Use of a stored-program computer is simple, cheap, and especially effective under saturating arrival rates.

The article presents three case studies of intensive music therapy done on three different patients at the Music Therapy Center in New York City. The patients were referred to weekly individual sessions and participated in small-group musical activities and in art or dance programs. The treating psychiatrist indicated immediate goals on the Center's referral form which involves bringing changes in patients' behavioral modes or patterns, that enables them to function on a more mature level.
