Tone Deaf

The other day, Danny went out and bought a cheap little electric guitar. He was way excited and when I came home from work he asked if I would help him tune it. So he played a note on the computer and then on his guitar and I'd tell him to make it higher or lower. Most of the notes were 1 1/2 to 2 full steps too high or too low. I just figured he hadn't tuned it yet so I helped him out. Later that night we were talking and he said "Before you came home from work I had tuned the guitar about four different times." and i said "what?! Are you kidding me? Did you really think it was in tune when I had gotten home?" and he said "Yeah! I thought it sounded great! and then I'd go to play a chord and think it sounded awful. I thought each note was perfect." My poor husband. He is ridiculous tone deaf.
