Let's chat: Tune before you play:
When I was in high school I took a guitar class. The teacher was awesome! He was the orchestra teacher and the guitar teacher. He played all the instruments very well. My first year of Guitar he taught us all techniques and music theory (of which I don't remember much). The first weeks we learned about the notes, quarter notes, half notes, whole notes, rests, eight notes, time signature and a lot of other things. One of the most important lessons was hot to tune. We played the E note which is the sixth string and the lowest note. We would also have to sing the note to memorize the sound.
