working on reading music and went back to GF1. I played the E on the open 6th string and then also on the 5th fret of the 5th string. They sound different to me. They are supposed to be the same note, right? If so, should they sound the exact same? I used my electronic tuner to test this. The guitar is in tune when I play the open 5th and 6th strings, but when I play the 5th string, 5th fret it's not an E note according to my ear or the tuner either (tuner says it reads as a D note, and not an "in tune" D either).

I've noticed some of my chords sound bad to me (don't know if they are, I am new to this and don't profess to have an "ear" - it just sometimes sounds bad, like the D chord).

Any thoughts? Could this just be the sound of an inexpensive beginner guitar? I did change strings for the first time about a week ago, but I can get the guitar in tune)
