دقّي يا مزيكا.. كيف تتلاعب الموسيقى بمشاعرنا؟
في هذه الحلقة من برنامج الدحيح مع أحمد الغندور، نبدأ من سؤال بسيط: لماذا تتكوّن الموسيقى من سبع نغمات؟ وكيف أصبح تردد 440 هرتز معياراً عالمياً لضبط الآلات الموسيقية؟نعود إلى فيثاغورس لنكتشف كيف وُلد السلم الموسيقي، ولماذا تبدو بعض الأصوات متناغمة وأخرى نشازاً، كما تكشف الحلقة كيف تتلاعب النغمات بالمشاعر والدوبامين لتصنع الحزن والفرح، وكيف نروِّض الترددات ونخلق الجمال من قلب النشاز، لنشكل ذائقتنا وثقافتنا الإنسانية الخاصة.
