Watch the The Hard Mute Bounce (in E) online guitar lesson by Freekbass from 50 Freekbass Licks You MUST Know
This E minor pentatonic lick shows how you can create more feeling and groove in your playing by how you attack the neck with your left hand. By not fully pressing on the neck you create almost a clavinet or horn type feel.
Giving the notes and feel a more staccato feel help to make them punch more through the groove and other instruments when you are playing along, so your line does not get lost in the mix. You are still attacking at full force with your right hand, but with your left, you are not fully pressing down.
