You’ve hit on one of my per peeves about most crowd sourced chord sheets…
For some reason, chords that may repeat for several measures are only shown once. I guess more experienced players can figure this out intuitively. But it’s a lot to ask for most beginners.
I certainly struggled with it. My solution was to pencil in ALL the chords - positioned over the EXACT syllable of the word where the chord changes (it’s very common for a chord change to happen in the middle of a word).
Another thing to watch out for - alignment of lyrics with chord changes is often only approximate. The chord is positioned exactly over the first word of a line on the sheet…but you listen to the song, and you can hear that the chord actually changes either before , during, or after that word.
The good news is that - much of the time - the chord will change on the “1” count of the measure. I usually approach a new song sheet by singing along to the recording, and doing a “4 finger tap” for 4/4 songs, or “3 finger tap” for 3/4 songs.
I tap a different finger for each beat in the measure For 4/4 … 1 - thumb, 2 - index, 3 - middle, 4 - ring.
I pay attention to which finger is down when I hear the chords change, and how that lines up with the lyrics, and mark up my chord sheet accordingly.
It’s a lot of work, but brings clarity from confusion. It’s also a good way to develop your ear. Been doing this for a couple of years now, and I can now quickly tell if a chord sheet is wrong, and sometimes even correct on the fly.
Another really good option is to use the Moises app. It does a pretty good job of identifying chords, and they recently fixed it so it actually shows the chord changes properly lined up with the measures. Moises also lets you slow down the song , add a metronome click , loop sections, and isolate vocals and instrument. These features are a huge help in figuring out songs and developing your ear.
