Watch the No, Not One - 4 online guitar lesson by Richard Kiser from Gospel Fingerstyle Guitar
The first thing you need to learn in this song as in all the songs in this course is the melody. You want to remember that your fingers as singing the lyrics so stay tight on the melody. If you over play or paint too many extra chops and riffs in the song, you stand the chance of losing the listener because can't follow the melody. On this tune, the melody will follow the chord structure in one or more inversion of each chord. I will use two formations of the "D" chord in the lead line. When I play a two string harmony part as in the "No Not One phrase", the harmony notes are played on the 7th fret position of the "D" and then the 5th and 6th fret position of the "A", as they are played on the 2nd and 3rd strings.They are actually 2/3rds of the triad in each chord. Remember to use the middle and ring finger of the right hand to play these notes as you keep the thumb alternating the bass line. When you play the verse the second time, you can add a little more syncopation between bass and lead notes to give some variation. You can also add an extra chop or two in the second verse to add variation. Don't be afraid to deviate from my arrangement a bit to make it your own.
