Watch the Add The Maj 3rd: Over Dom online guitar lesson by Rob Garland from The Guitarist's Pentathlon

For this demonstration I'm using Cm pentatonic with added major 3rd (the note E) against a C7 vamp. Bending from the b3rd to the major 3rd brings out a bluesy quality whilst hammering on from the b3rd to the major 3rd lends itself to a jazzier type of sound.
