Correct way of retrieving the variable singer?

After having declared a getter method in header and implementation file, why is the below method wrong?

NSString * singer = [song getSinger]

header file:

@interface Song : NSObject {
NSString *singer;
}

-(NSString *)getSinger;

implementation file:

@implementation Song 

-(NSString *)getSinger {
return singer
}

because in objective c, getter methods are named using the name of the variable itself, not getVariableName. So if i had a NSString variable called dog the corresponding getter method for that variable would be 

- (NSString *)dog {

}

not 

- (NSString *)getDog {


}
