Flat notes can indicate a limited singing range. If you feel like you can't hit a high pitch (even though you can hear it) then you may need to open up the top of your singing range.
Here are 3 clever tricks you can practice at home to help open up your vocal range.
Meow - Placed behind the nose, meow like a little kitten. Elongate the vowels each time. Once you've got a hang of it, practice sliding down pitch, into a lower voice.
Wheeee- Like when you're a child, being pushed on the swing. Wheeeeeeeee. Feel it resonate in your forehead and behind your noise.
'Witchy' Nasal Laugh - He, he, he, he heeee. With the back of your tongue sitting high, touching your velum (soft part in the roof of your mouth), start to mix- or bridge- between your speaking voice and upper head voice.
