Jigs are in 6/8 time, with two beats divided into two groups of three eighth notes, so alternate picking doesn’t really work for jigs. Instead, in traditional Irish music the players of plectrum instruments (guitar, tenor banjo, mandolin, bouzouki) usually pick jigs with a down-up-down, down-up-down pattern, which creates a groove that works well with 6/8 time. Slip jigs, which are in 9/8 time, are also played with the down-up-down pattern. Flynn gives you a few scale exercises you can use to practice jig picking.
