Watch the Finger Stretcher online guitar lesson by Jasper Mortier from 50 Blues Bass Licks You Must Know

All those little struggles I showed you in lick 39 can mess up your groove and can injure you, because you're forcing those tiny muscles and tendons. So you should try to get those struggles out of the way; both for you own health and your timing. A lot of people don't have control over the amount of muting they apply. Due to a lack of technique a certain part comes out muted in a arbitrary manner. This is mainly because it just takes a moment to shift from one note to another. And it takes a while to position your left hand fingers to be ready for the next note.Without knowing it, you might already have put your right hand finger on the string to be ready to pick the next note. If you’re not aware of this, it will limit your possibilities. Practice this sustaining of the notes - or tying the notes together - for instance while practicing scales. Try I-III-II-IV etc. and back or VIII-VI-VII-V etc. over a major scale. Later on do this over two octaves, with different intervals. Create your own exercises!
