I'm trying to learn to read music. Not easy to do when you can already play, and you are struggling to figure out if that dot is a C or a D and wait, was there a sharp back there?... I have no idea how a piano player can read two different lines at the same time, one for each hand, especially since the lines do not equate to the same notes... Anyway... What is the purpose of showing two tied notes in the notation? For example, two tied eighth notes, which is played as one quarter note. So, why not show a quarter note? This makes no sense to me. Also, I have seen some notation where, in a sequence of 4 sixteenth notes, the first note is shown tied to the third. Huh?!?!
