Self-taught player here with very rudimentary knowledge of theory so please go easy on me! The notes highlighted in yellow are confusing me a bit, as they are the same note, but one is a minim and the other a crochet.
I feel like I should be playing the minim and hold it while I play the the next notes. Is this correct?
If yes, why is that same note written twice on the bass clef, as two seperate notes (a minim and a crochet)?
