Doc... that happen to me last week.. hooked up with this Pastor that plays both bass and lead, been playing for years... he has played for Al Greeen and other Foks..but any who, was down at his church and was going over some songs..just playing around..*smilin* so he started to play "lead on me" so I started the song in ah major scale pos... (with my middle finger) so i would not have to shift my hand..as I was playin the song... he was like...NO THATS NOT RIGHT I WILL NOT LET YOU PLAY THE SONG WRONG..!!... now mind you, his whole thing for jump; was to play the song without shiftin my hand going from on note to the next... so I was like ..oook... He wanted me to start in the minor pos...fine with me.... so I played it in that position,and I was just gonna leave it at that... you know, His ah pastor, played with all types of fok.. but in my spirit I was like nawww I have to let him see that this is "wrong" or I should say wrong for me.. in that key and way he was showing me how to play the song..any who, it got ah lil heated..but he seen tha light...and was like "ok"....
