Watch the Off Beat Tension online guitar lesson by Tom Dempsey from 30 Jazz Arpeggio Licks You MUST Know
The Maj7b5 chord has a distinctive tension associated with the presence of the b5 interval. This is what gives it a very unique character that is both grounded and unsettling at the same time. In this example, we play an idea based out of this sound that is played over a bossa groove. Here too we bring in rhythmic tension in the syncopated manner that we play the lick. This is a trademark aspect of the rhythmic sound of Brazilian music and one that you should become comfortable with.
