This Weekly Workout is titled Rhythm Rudiments, which will teach you to use drum practice patterns to hone your picking technique and create new sounds. From Sean McGowan’s introduction:
The practice habits and routines of skilled, competent drummers are among the most organized, disciplined, and comprehensive of any musician. In this installment of Weekly Workout, we’ll take a look at a few of the more common drum rudiments and apply them to the guitar, specifically to picking, strumming, and fretting patterns. By adapting some or all of these patterns into your playing— especially for lead work—you can expect to develop some serious rhythmic acuity, pick speed, and new phrasing ideas.
The Weekly Workout is a series of exercises made up of interesting technical workouts that will get your fretting- and picking-hand fingers working in different ways, and offer musical studies that will help you visualize and explore the fingerboard. In every lesson, you'll get a different exercise to work on for each week of the month, as well as a few extra variations and extended practice ideas. Although we're presenting these as weekly exercises, there are numerous ways you can approach them, of course. Do whatever feels right for you.
