It seems there are too many notes in the treble clef below. The time signature is 4/4 yet there it starts with a quarter rest, then a dotted quarter, then 6 eighth notes. This adds up to more than four quarter notes. What does this mean? And what is the meaning of the eighth rest below the quarter rest at the beginning of the measure?
What you're looking at is two separate voices. In more complicated music, we sometimes write out two independent lines (or voices) on a single stave.
The first voice in this piece comprises the crotchet rest, followed by the quavers C+G, C+G tied to another C+G, then C, D and D again. This adds up to four crotchets.
The second voice comprises the quaver rest, the dotted crotchet E, the crotchet E, the quaver rest, and the G+E quaver that is tied into the next bar. This also adds up to four crotchets.
There is only a single voice on the bass stave.
The reason I know this, is because of the direction of the note stems. See how the first voice only has stems that point upwards? The second voice all points downwards. I know which rests to associate with each voice through the vertical positioning of the rests on the stave, and also because there's only one interpretation which will allow the bar to add up.
The music notation is correct, but possibly a bit odd if your not used to it. Seperated out it would look like this:
