Today i had a guitar lesson and at around 4:30 pm i walked to cadenza and met with my guitar teacher. I took out my guitar and got my music and then followed him into the room where the lesson was to take place. We started out tuning like we always do and my guitar was actually somewhat in good tune (it usually isnt). We started to play christensen 5ths and that was pretty easy because its just chords and once you know the chords you just gotta read the progression and your set. Then my guitar teacher wrote down the g major and a major and the a flat major and the g flat major scales. I also learned what a "core note" was, its the note which the scale was given its name for. And he told me that you can always tell what the core note is because the scale sounds unfinished if the core notes are excluded. Then we ran out of time I put away my guitar walked up some stairs and starting to walk home. (it was already dark by 5:00 pm!) i was amazed when i was walking home that it was dark.
