A chord is a group of three or more notes played together. Chords are commonly played by guitarists and keyboard players etc. On the bass guitar, chords are played one note at a time. This is called an arpeggio. The most important chords to learn are the major chord (e.g., C major) and the minor chord (e.g., D minor).
These chords are based upon the major scale. C is a shorthand way of writing C major. It applies to all major chords. Dm is a shorthand method of writing D minor. It applies to all minor chords. The examples below are commonly used arpeggios. It is important to memorize these arpeggios as they will become very useful in playing country bass. These arpeggios start on the root note.
