Book excerpt: ‘Neuro-management’ (‘NM’), classifies ‘Happiness’ into: ‘Smart Happiness’ that comes transiently with a smart release of the happiness neuro-chemical Dopamine; ‘Short-lived’ or ‘Short Happiness’ where the happy experience is retained a little longer and then gets stored in the long-term memory storage, retrievable on demand; and, finally, ‘Sustained Happiness’ which is long-lasting. ‘Bio-musicology’ is an offshoot of ‘NM’. It deals with the impact of music on body, brain, mind and soul. This book discusses, with diverse examples, how music can have ‘magical’ effects producing both ‘Smart’ and ‘Short’ varieties of happiness. The author believes that, if properly applied with clear understanding of the patient’s pathology and the impact of the sonic vibrations, music can also serve as ‘medicine’ and provide ‘Sustained Happiness’.
