In instruction in music, as in other related fields, the outstanding feature of the biennium 1916-1918 is the interference or readjustment occasioned by the European War. On the whole, although there has been some serious disarrangement, the direct or indirect benefits overbalance the losses. In the present rapid summary it will be convenient to mention (1) one or two lines of disturbance from war conditions; (2) several directions in which these conditions have induced novel efforts; and (3) certain points of discussion or progress not connected with war conditions. The following topics are covered: (1) Depletion in the number of teachers and pupils; (2) Some decrease among independent schools; (3) The transference of music teachers into Army work; (4) Military band development; (5) Camp singing and community music; (6) Discussions about standardization; (7) School credits for outside music study; (8) Other points of progress in public schools; and (9) Notable features in private instruction.
