Re: Pakistani Singers
Yes there is something right or wrong in music. Something which matches with the overall song is right. Besides every instrument should be tuned, regardless what tune it is played on.
Commercial music is for others to listen to, so one cannot say I will do whatever I want.
P.S. Tuned instrument means it makes one note at a time when played or stirred. Not one and half or two noted. Otherwise it will clash with other instruments.
Those who understand music know this. Unfortunately many musicians do not pay attention but a lot do.
