Aimed at intermediate to advanced players, this musical exercise is based around major and minor 7th arpeggios, so it’s not only a useful workout for your hands, it’s actually fun to play and sounds great. In particular, it’s a perfect exercise for co-ordinating your picking thumb and fretting hand, before working up speed and adding your remaining picking fingers on the higher strings. As Scott mentions, you’ll want to concentrate on gently “grazing” the strings as you build up speed to ensure this is a flowing, sweet-sounding workout!
