An arpeggio breaks up the notes of a chord such that they are played one by one, rather than all at once, to create a chordal pattern.
Arpeggios are often used to accompany melodies (from Mozart to pop) or to add texture and depth to a piece of music.
For example, the minor perfect chord of C is built on the notes C, E♭, and G (which are 1, ♭3, and 5).
This exercise presents melodic contexts for the notes in a perfect minor chord. It will help you immerse yourself in the emotion color of minor chords.
To get the most out of this exercise, sing the arpeggio of the perfect minor chord while paying particular attention to the minor third (3♭). This is what gives the chord its color. You can then change the starting note to explore the chord's inversions. For example: 1, 3♭, 5 and then 3♭, 5, 1 etc.
