Guitar

Im looking forward to mastering the guitar, a very nice instrument. just started today, and I totally suck. Im fingers are a bit to chubby, and my guitar is kinda out of tune, I mean, its not been played for, like, 5 years, and its not really mine.

Im trying to understand whats fret, and why the chords show in an upside-down manner.

Haiz...hope I can play one song, let along master it.
