Is it common to have a hard time learning to strum with a pick? When I use my thumb everything is smooth and I can hear the song and the rythymn but when I use a pick I just hear a bunch of rough noise with no rythymn ? I have layed ukulele for about 3 years and so use to just playing chords and rythymn strumming with my thumb. I do not know if that has anything to do with it but I feel I need to solve this issue
