Handed down: Research suggests prehistoric humans played the 'drum' from whatever material they found suitable, borrowing from our ancestral primate cousins.
During the last a few months, several groups have come up with interesting publications on how music affects the mind. The first is a report on March 1 from a group from Indiana University in the U.S., stating that
music may overcome delirium in critically ill patients. Such patients experience acute mental disturbance, with speech disorder and hallucinations. The researchers attempted to try music as a drug-free intervention in 117 such patients, and gave half of them music - either their own personally chosen music (PM), or relaxing slow tempo music (STM), and compared them with a control group which was not offered music. The music was offered to the experimental group for 1 hour, twice daily for a week, and their progress noted. Results revealed that such music delivery (PM or STM, either was OK) reduced the incidence of delirium.
When audio-books were offered instead of music, it did not help! The STM chosen had relaxing (60-80 beats per minute) classical music, native American flute sounds, or relaxing piano music — all preselected by a board-certified music therapist. They concluded that music is a useful non-pharmacological intervention for critically ill patients.
A little earlier was published a report in
Current Science (118(4), 612-620; 2020 ) from Dr. B. Geethanjali of SSN College, Chennai, and her colleagues, titled "Evaluating the effect of music intervention on hypertension". They did a randomised controlled assessment of 200 high-blood-pressure patients, measuring their
heart rate, respiratory rate (RR) and mean arterial pressure (MAP), and found that these parameters declined after music intervention for one month. The researchers chose to offer music intervention, along with the regular treatment, and chose the raga Hindolam (or Malkauns) — a pentatonic, 'low arousal', and pleasant one. (As we all know and experience, fast music and rhythms are 'high arousal', and excite us).
About this time also, the well known music therapist, Rajam Shankar of Hyderabad came out with a scholarly and well-researched monograph: "the healing power of music", with details on the kind of ragas that can be used in therapy, and a detailed description of as many as 35 known Carnatic music ragas (many common to Hindustani music too), and some case studies.
