DIY Uke Learning: Ukulele Aerobics: A 40-Week, One-lick-per-day Workout Program for Developing, Improving, and Maintaining Ukulele Technique is a comprehensive course that introduces everything from moveable chords and flatted fifths to the mysterious 7#9 chord. The succinct, clearly laid-out, daily lessons compose a series of weekly workouts, each focusing on chord vocabulary, strumming techniques, fingerstyle tips, a scale exercise, and pointers on using legato, licks, and riffs.
