I have listened to many good songs made by the members in this forum, and also read the comments they send together with the songs. Sometimes they say a variant of the following
"I know the vocal could be bether, but I am so tired of repeating myself and take retake after retake"
And of course it is dufficult. We sit alone in our small "studio" and try to sing like we are in front of an audience.
The next words is not mine, but written by a proffesional song teacher:

You are bored with the song. Distinguish this from being bored with COMMUNICATING THE SONG.
Performance requires vitality.

You have failed to understand, appreciate or project the meaning of the song. If you dont know the meaning of certain words or phrases- find out. Know what you are saying throughout the song.
Sing it from your personality.
End of sitat.

Also remember that you can syncopate some words, or maybe some words dont have to be sung at all. thy to resitate some of the words.

I think that it will be easier to make a decent vocal recording if we seperate the vocal into two cinds of moods.
First we are recirding the song the best we can to see if it works together with our arrangement, then we recording the vocal with this in mind that we are trying to COMMUNICATE THE SONG.

Best regards
