Correct way of retrieving the variable singer?

Question

After having declared a getter method in header and implementation file, why is the below method wrong?
NSString * singer = [song getSinger]
header file:
```objective-c
@interface Song : NSObject {
NSString *singer;
}
-(NSString *)getSinger;
```
implementation file:
```objective-c
@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 {
}
```
