Hi @Rahul0074, let me see if I can help out here!
I am afraid that i do not understand what you mean by "illumination bar music beat", please do elaborate as much as you can and I will do my best to assist you! Also if you could provide some information on which Xperia model you have and which version of android you are running, that would be great! To find this information, Find and tap Settings > System/About phone.
Please return with this information and I will do my best to assist you!
