Watch the Chords online guitar lesson by Dmitry Lisenko from Percussive Acoustic Bass (Foundry)
Chords are made up of least 3 notes sounded together. The chords on bass are usually played without the 5th interval. When we play full chord in a low register, it sounds a bit dirty. If we take off the 5th interval, it sounds much better. Often chords are played with the right hand, and intervals only with the left hand as there are only 2 notes.
