There are many resources for practicing scales and arpeggios on the cello, but there are extremely few for practicing chords. Understanding chords on the cello can be a very useful skill for cellists for a variety of reasons, the most obvious of which is that chords appear a number of times in the cello repertoire. In addition, understanding chords
—helps you to think harmonically,
—helps you to better analyze music,
—improves your ability to sight-read and to play arpeggios and double-stops,
—helps the fingers of your left hand to work better together as a team, and
—facilitates composition and improvisation.
