Singing has anyone tried Karaoke and then tried to sing

[in a mo]

Has anyone sang with a Karaoke machine ,then tried to sing with a real musical instrument and found that they were singing out of tune .One of the reasons is that on a Karaoke machine there is a facility to change the pitch of the tuneing to match your voice,but when you try to sing with an instrument ,some people find it impossible to sing in tune ,this is because they are singing notes that are "Between the Cracks" for example on a Piano there are White and Black notes some people sing between the two
