growth hormone-releasing hormone (GHRH)
responding to music because vibrations from music stimulate plant growth hormones
This accounts for Growth Hormone Regulatory Hormone, also called Growth Hormone Releasing Hormone, and also GRHF (for Growth Hormone Regulatory Factor). This is one of the two hypothalamic hormones (or previously named 'factors') that, respectively, stimulate or inhibit the release of growth hormone from the pituitary gland. The other hormone that inhibits the release of growth factor is called Growth Hormone Releasing-Inhibiting Hormone (or factor).
