I received my Lanikai LU-21 Soprano Ukulele yesterday and was eager to start playing it. After trying and failing at the guitar, I figured a ukulele would be easier and fun to try. I tuned it up gCEA with my new Lanikai electronic tuner. I tried my first song (Row, Row, Row Your Boat) with the C and G7 chords and I just can't do the G7. Can you tell me what fingers to put on which strings/frets for the G7? I keep trying and trying to do it but I have trouble especially with putting my fingers on the 1st and 3rd strings on the same fret I believe. This is my first song to try and I don't want to get disappointed already. I tried the C chord but I just don't know if it sounds right. With an instrument that hasn't been played much, do the strings sound off? Do you press down the strings all the way? Maybe I am pressing the strings too hard. Thanks!
