I don't know about anyone else but would like to know if anyone else has ever noticed this. I play mostly mandolin in bluegrass jams and when I sing I sing usually sing in the key of "A". When playing the uke I will try a song in that key and really have trouble with hitting the notes. I am having a bit of trouble finding a good singing chord for the uke. Do any of you have this problem? What is your easiest chord to sing in?
