The number of possibilities which may be found on any one ward is so great that only the most general kinds of use will be mentioned. Pediatric wards are frequently arranged so that the acutely ill are segregated, and this permits ward music at most times. Where patients are intermixed, the attending physician will make the decision. The importance of scheduling for children is enhanced by the fact that most children prefer their music loud, and this can be especially annoying to the sicker children. As a general rule it might be stated that with the progress from childhood to old age, the preference shifts from fast loud high-pitched music to softer and slower music. The speaker volume on the pediatric ward may be increased to gain the attention of some children, and drown out the crying of others. Children can listen to the same set of records almost endlessly. They prefer to hear music with which they are acquainted. They like songs with words. One reason for hospitalization is to get the patient away from the annoyances and noises of home. One of the modern noises is the radio. Most patients sleep and need more sleep than well people. In most hospitals certain hours of the day are chosen for rest in the hope that the patients will fall asleep. The usual period for daytime slumber is directly after lunch. The filling of the stomach is in itself a soporific. Warmth, darkness, and physical relaxation increase the tendency to sleep. Since there is no universally sleep-inducing music, music should be avoided at this time. It may keep some awake. If the patient is in a private room and is willing to be played to sleep it should be attempted. It must be remembered that if the music is sufficiently interesting or if the reproduction is poor or scratchy it may prolong wakefulness or even prevent sleep. At those times when slumber music is requested by the physician or the patient, a few common sense rules should be followed. For children vocal lullabies should be tried. Slumber music should not be played for more than fifteen minutes. If it has not been effective in that period, silence is indicated. Admission to a hospital usually means new eating and sleeping habits for the patient. The hours for each are frequently earlier than previously. Day-time naps and early “lights out” make it difficult for some to fall asleep promptly at night for the first few nights. Slumber music should take the form of restful music. The final fifteen minutes of the day should be given over to sweet melodies of old time favorites which may recall old pleasant memories and possibly place the patient in a “dreamy” mood of relaxation removed from the specious present and its worries. The operator of the sound control should gradually and imperceptibly reduce the volume so that the final moments are barely audible.
