Help with thread lib working with header files

[tony1420]

i have a header file that i made a class in, so i defined the class and such but when i try to use thread to access a function in the class

error C3867: 'TTT::music': function call missing argument list; use '&TTT::music' to create a pointer to member f:\c\tttclass\tttclass\main.cpp 33

not understanding that error as i have the function called music that does not take an argument

//in header file
class TTT{
public:
	void display(char position[row][column]);
	void music();
};


//in main.cpp


thread t1(play.music);
	t1.join;

thank you for your time
