In this 15/16 example, we'll be using 16th notes exclusively as we play a few arpeggios.
I'd recommend using alternate picking while you play this, and also starting on a downstroke with each measure. However, watch out for the last note in each measure. Since the last note in each measure is a downstroke, and the first note in each measure is also a downstroke, that means when you go from one measure to the next you'll have to do 2 downstrokes in a row to keep the picking pattern going.
