Hey my mom wouldn't let me play guitar because i already play piano clarinet and trombone so i made a deal and said if i showed her i was real good she will buy me a guitar. this is what i did

get some classical music try classical guitar tab or if you play electric try olga and get something easy

practice it

make it look and sound complicated by putting in easy hammer ons and pull offs and slides

try something by ace frehley if your mom doesn't play guitar it can look fast and complicated.

this took me two months it may seem along time but i got this awesome guitar.
