Arpeggios

This week I am introducing you to arpeggios.
Arpeggios are just the notes of the chord played in a row. If we extend our triad with another third we get four note chords, very popular in jazz.
So the harmonization of the major scale changes as follows:

I maj7, II min7, III min 7, IV maj7, V7(dominant), VI min7, VII m7b5
