I sometimes sing from a song book that contains the lyrics between two staff lines that show the notation for a piano.
What I do is to try to listen only to the sound of the music so as to stay at the right location but this does not always work that well.
I have also tried to determine the current location within the song by looking at the notation and matching this with the song at the current point. This has not worked very well, partially because the music at times seems to move faster than than my interpretation and partially because some notation is not really clear to me.
What I wanted to ask is whether learning the notation would help in singing, or if this is more of a matter of me getting used to particular songs?
If learning notation can help in this, are there some particular aspects that would be especially beneficial to focus on (like maybe chords)?
