My Mandolin hobbie update!

I thought I needed to update my progress on my mandolin lessons. I bought a book and a DVD of the same teacher, and so far I have mastered 1 scale- G, 4 chords,G,C,D,A, and 3 songs, all in the key of G, Yankee Doodle, Worried Man Blues, and Wildwood flower. My Dad is so proud, he likes me to come by and "pick" with him. He wanted to play my mandolin so bad, I ended up ordering one for him. He loves to pick on it and it is fun to have someone else play along with me. I know Mom is probably tired of hearing the same song, along with all the mistakes I make. Dad plays his Martin Guitar while I play the melody and try to keep up. He just gets faster and faster, while I am struggling to hit the right string. I am surprise I have gotten this far. It is fun and a real challenge to do so many things at one time. Read the music, find the string, and do the fingering on the left hand, along with keep the tempo, and think about the words to the song. I love all kinds of music and this is just a way to enjoy the sound. Dad wants to have a picking at his house and let me play my one or two songs. I don't know if I am ready to jump into the middle of all these experienced men and women, I don't want them to think I am replacing any of them. This is my Dad's whole life. He looks forward to every opportunity to play with a bunch of people. I think I can take it or leave it. But for now, I am gonna give it a try.
