This Rolling Backup for Before I Met You is a great study for using rolls as backup in a song with waltz feel. The roll patterns end up being slightly different from songs in standard timing. Check out the banjo tablature, you'll use some forward rolls - TIMTIM, and also a forward backward roll - TIMTMI. As you can see, these roll patterns end up being 6 note patterns, instead of the 8 note patterns that are used in common timing.
If you notice, in each measure there is a 6 note roll pattern, followed by a single note and 2 pinches. This helps us create a solid and reliable rhythmic rolling pattern you can use to roll through the whole tune. Use the focus feature to listen to and practice measure 1. Do this and you will have the picking pattern you can use for the entire song. The only other thing you'll need to work on is switching to the C chord and D7 chords.
The A section is the verse, and the B section is the chorus. After getting down the basic arrangement, check out the licks. There you can explore variations by using different roll patterns and more authentic Scruggs style banjo vocabulary. Again, use the focus feature to listen to and practice these licks individually. Use the tempo slider to listen at speed at which you can understand them and play them. What works for one measure of G will work for another. For example, the lick for measure 1 will also work for measures 3, 5, 8, 10, 11, etc. Because the same chord is being played in those measures as well.
